Description

Technical Field

[0001] The present invention relates to the technical field of electrical digital data processing in architecture, and particularly to a method and system for building project cost management based on electronic information. Background Art

[0002] Building project cost management refers to a series of scientific management work such as predicting, planning, controlling, accounting, analyzing, and assessing the project cost at each stage of a building project (including decision-making, design, bidding, construction, and completion acceptance, etc.). The main purpose is to ensure that the project is completed with high quality within the budget, and at the same time improve the investment efficiency.

[0003] Building project cost management has always been one of the key issues in the construction industry, involving multiple links such as project budget, cost control, and settlement audit. With the maturity of computer technology, database technology, and communication technology, especially the application of technologies such as cloud computing, big data, and artificial intelligence, the informatization level of the construction industry has been significantly improved. For example: in cost management, establishing a BIM (Building Information Modeling) of the project based on the electronic information of the building project can realize the synchronous management of design changes, construction progress, and cost, so as to more accurately predict and control the project cost.

[0004] Among them, adjusting the thickness of components (i.e., the basic components of a building or structure) is a commonly used optimization means for controlling the project cost in building project cost management. For example, for a building floor slab, the thicker the thickness of the floor slab, the higher the material costs such as steel bars and concrete consumed during the construction of the floor slab, and the greater the self-weight of the floor slab, which increases the load on related components such as ground beams and columns supporting the floor slab, so the costs of related components such as ground beams and columns will also increase accordingly. In the existing design methods, manual calculation and two-dimensional drawing are usually used to adjust the thickness of components in the building to control the cost. However, this method is difficult to conduct a comprehensive structural analysis and optimization. Therefore, the design when adjusting the thickness of components is often not accurate and comprehensive enough, and does not fully consider the impact on other components when adjusting the thickness of components, and there are problems with the balance between safety and economy.

[0005] Therefore, how to improve the balance between safety and economy in building project cost management is an urgent problem to be solved at present. Summary of the Invention

[0029] The above part introduced the content of the exemplary implementation environment of applying the technical solution of this application. Next, continue to introduce the building project cost management method based on electronic informatization of this application.

[0030] To solve the problem of how to improve the balance between safety and economy in building project cost management in the prior art, the embodiments of this application respectively propose a building project cost management method based on electronic informatization and a building project cost management system based on electronic informatization. The following will describe these embodiments in detail.

[0031] Please refer to Figure 2 ,Figure 2 The flowchart of a building engineering cost management method based on electronic informatization provided by an embodiment of the present invention. This method can be applied to Figure 1 the shown implementation environment. It should be understood that this method can also be applicable to other exemplary implementation environments and be specifically executed by devices in other implementation environments. This embodiment does not limit the implementation environment applicable to this method.

[0032] As Figure 2 shown, in an exemplary embodiment, the building engineering cost management method based on electronic informatization at least includes steps S210 to S240, which are introduced in detail as follows: In step S210, obtain the building information model corresponding to the target building, and the building information model is established based on the engineering electronic information of the target building.

[0033] Among them, the target building refers to the specific building project that needs cost management and optimization.

[0034] Among them, the building information model (BIM) refers to a three-dimensional building model established based on digital technology, which contains all the detailed information of the building, such as geometric shape, material properties, etc.

[0035] Among them, the engineering electronic information refers to the data and documents used to construct the BIM, including but not limited to design drawings, construction plans, bill of materials, etc.

[0036] In step S220, extract the load transfer path and load value in the building information model, and based on the load transfer path and load value, establish a load transfer tree diagram of multiple components in the target building.

[0037] Among them, the load transfer path describes the force transfer route between different components in the building structure.

[0038] Among them, the load value is the quantified value of various forces applied to the building structure, such as wind force, snow load, etc.

[0039] Among them, the component refers to the basic unit that makes up the building structure, such as beams, columns, slabs, etc.

[0040] Among them, the load transfer tree diagram is a visualization tool used to represent how the load is transferred through each component in the building structure.

[0041] In step S230, analyze the influence of the thickness change of the component corresponding to each node in the load transfer tree diagram on the components corresponding to other nodes within a preset range, and determine the thickness change evaluation corresponding to each component.

[0042] Among them, a node refers to a point in the load transfer tree diagram, representing the connection point between one or more components.

[0043] Among them, the thickness change of a component refers to the change amount of the thickness of a certain component, which may affect its bearing capacity and cost.

[0044] Among them, the thickness change evaluation is to evaluate the impact of the thickness change of a certain component on the safety and economy of the entire building structure.

[0045] In step S240, based on the thickness change evaluations corresponding to the respective components, the adjusted thicknesses of the respective components are determined, and the construction cost of the target building is optimized based on the adjusted thicknesses.

[0046] Among them, the adjusted thickness of a component is the optimal thickness determined according to the thickness change evaluation.

[0047] Exemplarily, assume there is a multi-story office building project. First, establish the BIM of this office building, including engineering electronic information such as design drawings and material specifications of all floors. Next, extract the load transfer paths and load values of each floor slab and column from the BIM, and draw a load transfer tree diagram based on this. Then, analyze how the thickness change of the component corresponding to each node in the tree diagram (such as a certain column) affects the surrounding components (such as adjacent floor slabs). If increasing the thickness of a certain column can reduce the stress concentration problem of other components but will increase the cost, a comprehensive evaluation will be carried out to determine the optimal thickness. Finally, based on these adjusted thicknesses, optimize the construction cost of the entire building.

[0048] As can be seen from the above steps S210 to S240, in the solution proposed in this embodiment, by obtaining the building information model established based on engineering electronic information, various detailed information of the building can be integrated, including geometric shape, material properties, load conditions, etc.; by extracting the load transfer paths and load values in the building information model and establishing a load transfer tree diagram, the load transfer relationship between each component can be intuitively displayed, which not only improves the accuracy of analysis but also facilitates the identification of key paths and potential risk points; by analyzing the impact of the component corresponding to each node on other nodes within a preset range when the thickness changes, these impacts can be quantified and a thickness change evaluation can be generated, which helps to more scientifically evaluate the safety and economy of different thickness adjustment schemes; by comprehensively considering the impact of the thickness change of each component on other components, the safety of the overall structure is ensured, thereby reducing the cost of related components while maintaining the overall stability of the structure; according to the thickness change evaluation, select the optimal thickness adjustment scheme to minimize the material cost and construction cost, reduce unnecessary over-thick design, avoid wasting resources, and at the same time ensure that the structural performance meets the requirements.

[0049] In an embodiment of the present application, the engineering electronic information includes building design dimensions, component types, component specifications, component quantities, material specifications, and material unit prices. The building information model includes building model geometric information, component performance data, construction methods, material types, and procurement information.

[0050] Among them, the building design dimensions are the physical dimension parameters of the building, including but not limited to length, width, height, etc., and are used to define the specific scale of the building; the component types are used to describe different types of structural units in the building, such as beams, columns, walls, slabs, etc.; the component specifications are used to specifically describe the dimensions and technical requirements of each component, such as cross-sectional dimensions, steel bar configurations, etc.; the component quantities refer to the quantities of specific types of components, which help to quantify the materials and costs required for the building; the material specifications are the specific technical standards of building materials, such as concrete strength grades, steel grades, etc.; the material unit prices are the prices per unit volume or weight of materials and are used to calculate the project budget. Among them, the building model geometric information is the three-dimensional geometric data in BIM, including the building's external shape and internal space layout; the component performance data are the performance indicators of each component in terms of force, such as load-bearing capacity, durability, etc.; the construction methods are the technical solutions describing how to implement the building project, including the construction sequence, process flow, etc.; the material types are the lists of all different types of materials used in the project, such as concrete, steel, glass, etc.; the procurement information is the relevant information about material suppliers, delivery times, transportation methods, etc.

[0051] Exemplarily, assume that a bridge is being designed. First, it is necessary to determine the design dimensions of the bridge (such as the total length, span, etc.), as well as the required component types (such as bridge piers, bridge decks) and their specifications (such as cross-sectional dimensions, steel bar arrangements). Then, count the quantities of various components and determine the specifications (such as concrete strength grades, steel grades) and unit prices of the materials used. Based on this engineering electronic information, a detailed BIM can be constructed, which includes accurate building model geometric information, the performance data of each component (such as compressive strength), the construction methods adopted (such as in-situ casting method or prefabricated assembly method), the material types used (such as cement, sand and gravel, steel bars), and procurement information (such as suppliers, expected arrival dates).

[0052] In this embodiment, by recording in detail information such as the design dimensions of the building, the types, specifications, and quantities of components, fine control of the construction project is achieved, which helps improve work efficiency and accuracy; by clarifying the material specifications and unit prices and combining with the quantities of components, the direct cost of the project can be accurately calculated, facilitating cost control and optimization; through the detailed geometric information of the building model and the component performance data, potential risk points can be identified at an early stage, preventive measures can be taken, and the possibility of later modifications and rework can be reduced; by providing a comprehensive and consistent information platform, communication and collaboration between different professional teams are facilitated, and misunderstandings and conflicts are reduced; by reasonably planning the types of materials and procurement information, the effective utilization of resources is promoted, which conforms to the concept of green buildings and promotes sustainable development; based on detailed data support, the management can make more scientific and reasonable decisions to ensure the smooth progress of the project.

[0053] In an embodiment of the present application, extracting the load transfer path and load value in the building information model, and based on the load transfer path and load value, establishing a load transfer tree diagram of multiple components in the target building, includes: Through a pre-configured finite element analysis module, performing a load analysis on the building information model to obtain the load transfer path of the load in the multiple components and the load value on the load transfer path; Taking each of the components as a node, taking the load transfer path between the nodes as a directed edge, taking the self-weight of the component as the value of the node, and taking the load value as the weight of the directed edge, to complete the establishment of the load transfer tree diagram, where the order of the nodes is the order corresponding to the components from top to bottom in the building information model.

[0054] Among them, in construction engineering, when controlling the cost by adjusting the thickness or removing components, the load-bearing situation of the components is crucial for whether the thickness can be adjusted. For key load-bearing components, adjusting their thickness may have a greater impact on other components and even deteriorate the safety performance of the building. Therefore, first obtain the load-bearing situation of each component in the current building.

[0055] Among them, the finite element analysis module is a numerical simulation tool used for mechanical analysis of structures. By dividing the structure into multiple small units (i.e., "finite elements"), calculating parameters such as stress and strain of each unit, so as to evaluate the behavior of the entire structure.

[0056] Among them, the load analysis is a specific analysis type performed in the finite element analysis module, used to determine the responses of each component in the building structure under different loads, such as stress distribution and deformation conditions.

[0057] Among them, a directed edge, in graph theory, represents the connection between two nodes and has a direction. In this embodiment, the directed edge represents the direction and path of load transfer from one component to another.

[0058] Among them, the self-weight of a component refers to the weight of the component itself and is a constant load that must be considered in structural design.

[0059] Among them, the value of a node, in the load transfer tree diagram, the value of a node can represent certain attributes or states of the component corresponding to the node, such as self-weight.

[0060] Among them, the weight of a directed edge, in graph theory, the weight of an edge usually represents a certain measurement standard, which here refers to the load value on the load transfer path.

[0061] Among them, when performing load analysis on the building information model through a pre-configured finite element analysis module to obtain the load transfer path of the load in the multiple components and the load value on the load transfer path, a preset finite element analysis tool can be used to analyze the structure in BIM, identify how the load is transferred between each component, and calculate the specific load value on each transfer path.

[0062] Exemplarily, assume that a multi-story residential building is being designed. Refer to Figure 3 , Figure 3 , which is the schematic diagram of building load transfer provided by an embodiment of the present invention. As Figure 3 shown, in the building load transfer of this multi-story residential building, the components include components such as waterproofing, cast-in-place concrete roof slab, roof beam, frame column, etc. The load relationship between these components is marked by arrows. To ensure the safety and economy of the structure, it is necessary to analyze its load transfer path in detail. First, a three-dimensional model of this residential building is created in BIM software, including the design dimensions, material specifications, etc. of all floors, beams, columns, walls and other components; then, a pre-configured finite element analysis module (such as ANSYS, SAP2000, etc.) is integrated in the BIM environment. During load analysis, various loads acting on the building are defined, such as dead load (self-weight), live load (people, furniture, etc.), wind load, snow load, etc.; the finite element analysis module is started to perform load analysis on the model, calculate the stress and deformation conditions of each component under these loads, and at the same time generate the load transfer path and its corresponding load value. When establishing the load transfer tree diagram, each component is regarded as a node, such as a column, a beam, a floor slab, etc.; according to the finite element analysis results, the load transfer path is used as a directed edge, and a specific load value (i.e., weight) is assigned to each edge. For example, the load transferred from a certain column to its underlying foundation is 500 kN; the nodes are arranged in the order from top to bottom in the building information model to form a complete load transfer tree diagram.

[0063] In this embodiment, through the finite element analysis module, the load transfer path in the building structure can be accurately simulated and analyzed, avoiding the errors that may be brought by traditional manual calculations; based on the detailed load analysis results, the performance of each component under different loads can be comprehensively evaluated to ensure the overall safety of the structure; the load transfer tree diagram provides an intuitive tool to help engineers quickly understand and identify the critical path and potential risk points, facilitating the optimization design; by integrating the finite element analysis module through the BIM platform, the efficient collaboration among different professional teams (such as structural engineers, architects, construction management personnel) is promoted, reducing communication barriers and information loss; by accurately analyzing the load conditions of each component, the thickness of the component and other design parameters can be reasonably adjusted on the premise of ensuring the structural safety, realizing the effective control of costs.

[0064] In an embodiment of the present application, analyzing the influence of the thickness change of the component corresponding to each node in the load transfer tree diagram on the components corresponding to other nodes within a preset range, and determining the thickness change evaluation corresponding to each of the components, includes: Analyzing the association relationship between the components corresponding to each of the nodes in the load transfer tree diagram and other components connected in the thickness direction, and merging the nodes according to the association relationship to obtain a new load transfer tree diagram; According to the positions of the components corresponding to each of the nodes in the new load transfer tree diagram and the number of all components connected to the components corresponding to each of the nodes, analyzing the influence range of the thickness change of the component corresponding to the node on the components corresponding to other nodes, and obtaining the diffusion coefficient corresponding to each of the nodes; According to the load transfer situation of the components corresponding to each of the nodes in the new load transfer tree diagram and the diffusion coefficient corresponding to each of the nodes, analyzing the influence of the thickness change of the component corresponding to the node on the performance stability of the components corresponding to other nodes, and obtaining the thickness change evaluation corresponding to the components corresponding to each of the nodes.

[0065] Among them, due to the different relevant situations and load-bearing situations of each component and other components, when adjusting the thickness of each component, the degree of adjustability is different. For example, for a connecting component connecting multiple components or a component bearing loads from multiple sources, if its thickness is adjusted, it may affect the states of multiple other components, resulting in the adjustment of the dimensions and other attributes of multiple other components, and the large changes brought increase a lot of design costs. Therefore, when considering adjusting the thickness, for the components related to more components, the priority of adjusting them is lower to avoid increasing too much design cost.

[0066] Among them, the thickness direction refers to the measurement in the direction of the minimum dimension of the component, usually the direction perpendicular to the surface of the component. For example, the thickness direction of a floor slab is the direction perpendicular to its plane.

[0067] Among them, the correlation between the components corresponding to each node in the load transfer tree diagram and the other components connected in the thickness direction describes the mechanical and structural relationship between a certain component and the other components directly or indirectly connected to it in the thickness direction. For example, the relationship between a floor slab and the beam supporting it.

[0068] Among them, by merging the nodes according to the said correlation, through analyzing the correlation between components, nodes with similar or close connections can be merged into one node, simplifying the load transfer tree diagram for more efficient subsequent analysis.

[0069] Among them, the position of the component corresponding to each node in the load transfer tree diagram is the position of each node in the tree diagram, indicating the relative position of the component corresponding to the node in the entire building structure (such as from top to bottom, from inside to outside, etc.).

[0070] Among them, the number of all components connected to the component corresponding to the node is the number of other components connected to the component corresponding to each node, reflecting the importance and influence range of this component in the network.

[0071] Among them, the influence range of the thickness change of the component corresponding to the node on the components corresponding to other nodes is the range of influence of such a change on other components when the thickness of a certain component changes, which can be quantified by the diffusion coefficient.

[0072] Among them, the diffusion coefficient corresponding to the node is a numerical index used to measure the degree of influence of the thickness change of the component corresponding to a certain node on other nodes. The larger the value, the wider the influence range.

[0073] Among them, the load transfer situation of the components corresponding to each node in the load transfer tree diagram is used to describe the specific role of the components corresponding to each node in the load transfer path, including the amount of load transferred and its distribution.

[0074] Among them, the influence of the thickness change of the component corresponding to the node on the performance stability of the components corresponding to other nodes can analyze how the thickness change of a certain component affects the performance indicators such as the bearing capacity and deformation of other components, and evaluate the stability of the overall structure.

[0075] Exemplarily, assume that a multi-story office building is being designed and it is desired to optimize cost management by adjusting the thickness of certain components. This multi-story office building has several columns and floor slabs on each floor. Use the finite element analysis module to generate an initial load transfer tree diagram, where each node represents a component (such as a column, floor slab), and the edges represent the load transfer paths. Analyze the association relationship between the component corresponding to each node and the other components connected to it in the thickness direction. For example, the relationship between the floor slab on a certain floor and the four columns supporting it. If the functions of these columns are similar and the load transfer paths are similar, they can be combined into one node to simplify the tree diagram. According to the new simplified load transfer tree diagram, calculate the position of the component corresponding to each node and the number of all components connected to it. For example, the top floor slab is connected to four columns, and each of these four columns is connected to the floor slab on the next lower floor. Based on this information, calculate the diffusion coefficient corresponding to each node and evaluate the influence range of the thickness change. Conduct a detailed analysis of the load transfer situation of the component corresponding to each node to determine its role in the load transfer path. For example, how much load is transferred from the top floor slab to the four columns, and how much load is then transferred from these columns to the floor slab on the next lower floor. Assume that the thickness of the top floor slab is increased by 10%, recalculate the load transfer path, and analyze the impact of this thickness change on the performance stability of the components corresponding to other nodes (such as columns, floor slab on the next lower floor). For example, increasing the floor slab thickness will increase the load on the columns, and it may be necessary to adjust the cross-sectional dimensions of the columns to ensure their load-bearing capacity.

[0076] In this embodiment, by analyzing the influence of the thickness change of a component on other components, it is possible to accurately identify which components' thickness adjustment will have a greater impact on the overall structure, so as to carry out targeted optimization design. Using the diffusion coefficient and the load transfer situation, comprehensively evaluate the impact of the thickness change on the entire building structure to ensure that no new risk points are introduced while adjusting the thickness. Combine nodes with similar functions or close associations to simplify the load transfer tree diagram, reduce the calculation complexity, and improve the analysis efficiency.

[0077] In an embodiment of the present application, analyzing the association relationship between the components corresponding to each node in the load transfer tree diagram and the other components connected to them in the thickness direction, and combining the nodes according to the association relationship to obtain a new load transfer tree diagram includes: For the component corresponding to any one of the nodes, obtain the number of load source components of the component and the other components connected to it in the thickness direction, and the number of load transfer components of the component and the other components connected to it in the thickness direction; Compare the number of load source components with the number of load transfer components to obtain an association degree, and the association degree is used to indicate the association relationship; Merge two components whose degree of association is greater than the preset degree-of-association threshold to obtain the new load transfer tree diagram.

[0078] Among them, when constructing the load transfer tree diagram, each component is taken as a node. However, in an actual building, many components are not independent. For each component and the components connected to it in the thickness direction, when the thickness of one component changes, it may cause the thickness of other components to change accordingly. Therefore, when considering adjusting the thickness, the associated components need to be considered together. Analyze the association relationship in the thickness direction of each component to merge the strongly associated component nodes for subsequent analysis.

[0079] Among them, the number of load source components refers to the number of other components that are directly or indirectly connected to the component corresponding to a certain node in the thickness direction and transfer loads to this component. For example, the number of load source components received by a certain column from the floor slab and the wall.

[0080] Among them, the number of load transfer components refers to the number of other components that are directly or indirectly connected to the component corresponding to a certain node in the thickness direction and transfer the loads out. For example, the number of load transfer components that a certain column transfers the loads to the foundation and other support structures.

[0081] Among them, the degree of association is a numerical index calculated by comparing the number of load source components with the number of load transfer components, and is used to measure the tightness of the association between two components. The higher the degree of association, the stronger the mutual dependence between these two components.

[0082] Among them, the preset degree-of-association threshold is a preset value used to determine which components have a high enough degree of association to be merged into one node. It is usually determined according to specific engineering requirements and empirical data.

[0083] Exemplarily, for two connected components, when the situations of the loads received from the upper level and the loads applied to the lower level by the two components are more consistent, then when the thickness of one of the two connected components changes, it often affects the thickness change of the other component, and these two components are strongly associated. When analyzing the load change caused by the thickness change, if the strongly associated components are analyzed in isolation, it may lead to inconsistent changes between the two, which does not conform to the actual situation. Therefore, taking the i-th component as an example, obtain each component connected to this component in the thickness direction and analyze its association relationship.

[0084] Exemplarily, the representation of the degree of association between the i-th component and the j-th component connected to it in the thickness direction can be: Among them, Represents the degree of association between the i-th component and the j-th component connected in its thickness direction; Represents the Sigmoid function, which is used for linear normalization in this embodiment; Represents the number of loads from the same component received by the i-th component and the j-th component connected in its thickness direction (i.e., the number of load source components with the same source); Represents the total number of load source components for all sources of the i-th component and the j-th component connected in its thickness direction. The same component is only counted once; Represents the number of times the load of the i-th component and the j-th component connected in its thickness direction is transmitted to the same component at the next level (i.e., the number of load transmission components with the same transmission target); Represents the total number of load transmission components with the same transmission target for the i-th component and the j-th component connected in its thickness direction; and Adding 1 later is to prevent the denominator from being zero.

[0085] Among them, and can represent the association relationship between the i-th component and the j-th component connected in its thickness direction. When these two values are larger, it means that the i-th component and the j-th component connected in its thickness direction are strongly associated.

[0086] Exemplarily, the preset association degree threshold is 0.8. Two components with an association degree greater than 0.8 are strongly associated. Merge all strongly associated component nodes and update the load transmission diagram of the current building. Merging the strongly associated component nodes can avoid inconsistent situations and ensure the accuracy of the analysis.

[0087] In this embodiment, by merging component nodes with high correlation, the load transmission tree diagram can be significantly simplified, reducing the computational complexity and workload, and improving the analysis efficiency. The merged nodes can more accurately reflect the interaction between components in the actual structure, avoiding errors caused by overly detailed division, and improving the overall analysis accuracy. The simplified load transmission tree diagram is easier to identify key paths and potential risk points, helping engineers make more scientific and reasonable thickness adjustment decisions to ensure the safety and economy of the structure.

[0088] In an embodiment of the present application, analyzing the influence range of the thickness change of the component corresponding to each node on the components corresponding to other nodes according to the positions of the components corresponding to each node in the new load transmission tree diagram and the number of all components connected to the components corresponding to each node, and obtaining the diffusion coefficient corresponding to each node includes: For any of the said nodes, take all the nodes with zero in-degree in the new load transfer tree diagram as starting points, and determine the number of nodes traversed by all paths between each starting point and the node. Take the largest number of nodes as the maximum depth of the node, and the maximum depth is used to indicate the position of the component corresponding to the node. Combine the maximum depth and the number of all components connected by the component corresponding to the node to determine the diffusion coefficient corresponding to each node.

[0089] Among them, when controlling the construction project cost by adjusting the thickness of components, components with less influence on other components are often preferred. If the number of connecting components of a node is larger, it means the structure related to this node is more complex. If a node is more downstream in the load transfer diagram, it means the load borne by this node is more complex, and the priority as an adjusted component is lower. The diffusion coefficient of each node can be obtained through the number of all components connected by the component corresponding to the node and the position of the node in the load transfer diagram.

[0090] Among them, in graph theory, the in-degree of a node refers to the number of edges pointing to this node. In the load transfer tree diagram, a node with zero in-degree means a node that no other component directly transfers load to it.

[0091] Among them, the starting point refers to all nodes with zero in-degree in the load transfer tree diagram. These nodes usually represent the initial load sources (such as floors, roofs, etc.).

[0092] Among them, the number of nodes traversed by all paths between the starting point and the node is the total number of nodes passed through on all possible paths from each starting point to the target node. This value is used to calculate the maximum depth.

[0093] Among them, the maximum depth is the number of nodes included in the path with the largest number of nodes passed through among all paths from the starting point to the target node. It reflects the relative position of the node in the entire structure.

[0094] Among them, the diffusion coefficient is a numerical index used to measure the influence range of the thickness change of the component corresponding to a certain node on other nodes, and it can be determined by combining the maximum depth and the number of all connected components.

[0095] Exemplarily, taking the k-th node as an example, first obtain the position of the k-th node in the load transfer diagram. Taking all the nodes with an in-degree of 0 in the load transfer diagram as the starting points, obtain the number of nodes that need to be traversed for all the paths between each starting point and the k-th node (if there is no path between the starting point and the k-th node, it is recorded as -1), and take the maximum value among all the node numbers as the maximum depth of the k-th node. The smaller the maximum depth, the more upstream the k-th node is in the load transfer diagram. Then, in combination with the number of components connected by the component corresponding to the node, obtain the diffusion coefficient.

[0096] Exemplarily, the expression of the diffusion coefficient of the k-th node can be: Among them, is the diffusion coefficient of the k-th node; represents the linear normalization function; represents the maximum depth of the k-th node; represents the number of all components connected by the component corresponding to the k-th node.

[0097] Among them, The magnitude of reflects the influence range on the surrounding components of the component corresponding to each node when the thickness of the component corresponding to each node changes. The smaller the value of, the smaller the influence range of the k-th node.

[0098] In this embodiment, by calculating the maximum depth and the diffusion coefficient, the influence range of the thickness change of a certain component on the entire structure can be accurately evaluated. This helps to identify the critical paths and potential risk points, ensuring the safety and economy of the design. A quantitative method is provided to evaluate the influence of the component thickness change, helping engineers make scientific and reasonable optimization decisions. For example, on the premise of ensuring the structural safety, reasonably adjust the component thickness to reduce the material cost.

[0099] In an embodiment of the present application, analyzing the influence of the thickness change of the component corresponding to the node on the performance stability of the components corresponding to other nodes according to the load transfer situation of the components corresponding to the nodes in the new load transfer tree diagram and the diffusion coefficients corresponding to the nodes, and obtaining the thickness change evaluation of the components corresponding to the nodes, including: For any node in the new load transfer tree diagram, obtain all the load transfer paths where the node is located; According to all the load transfer paths, determine the number of load transfer paths, the load value, and the number of nodes passed between the node and any upstream node; Determine the influence coefficient of the node on any upstream node by combining the number of load transfer paths, the load value, the number of nodes passed through, and the diffusion coefficient corresponding to each node between the node and the upstream node. The influence coefficient is used to indicate the influence of the thickness change of the component corresponding to the node on the performance stability of the component corresponding to any upstream node. Determine the thickness change evaluation corresponding to each node by combining the influence coefficients of the node on all the upstream nodes.

[0100] Among them, when the thickness of the component changes, it may also affect the performance stability of the adjacent components on the load transfer path. The adjacent components may further spread this influence to the components adjacent to them, thereby generating a butterfly effect. When changing the thickness of the component, the resulting performance impact will take the node with the thickness change as the diffusion origin and affect the nodes on all load transfer paths where the node is located. The thickness change evaluation of each node can be obtained according to the load transfer situation of each node and the diffusion coefficient of each node.

[0101] Among them, the number of load transfer paths refers to the number of all possible load transfer paths between a node and any of its upstream nodes. Each path represents the specific route of the load transfer from one component to another component.

[0102] Among them, the load value is the specific load value on each load transfer path, indicating the magnitude of the force transmitted on this path. These load values are usually calculated by the finite element analysis module.

[0103] Among them, the number of nodes passed through is the number of all nodes passed through on a certain path between a node and any of its upstream nodes. This value reflects the number of intermediate components involved in the load transfer process.

[0104] Exemplarily, obtain all the load transfer paths where the k-th node is located. Taking the k-th node to the r-th node upstream of it as an example, analyze the influence coefficient of the k-th node on the r-th upstream node. Among them, the expression of the influence coefficient of the k-th node on the r-th upstream node can be: Among them, represents the influence coefficient of the k-th node on the r-th upstream node; represents the Sigmoid function, which is used for linear normalization in this embodiment; represents the number of load transfer paths between the k-th node and the r-th node; represents the k-th node receiving the load value on the m-th load transfer path from the r-th node; Denotes the number of nodes passed by the th load transfer path between the kth node and the rth node (when calculating this number of nodes, the kth node needs to be included, but the rth node is not included); Denotes the diffusion coefficient of the hth node passed by the th path between the kth node and the rth node, where when h = 0, it represents the kth node.

[0105] Among them, The larger the value of, the greater the load indicates. When the thickness of the node changes, it is more likely to affect the performance stability of the components corresponding to other nodes.

[0106] Obtain the influence coefficient of the kth node on all its upstream nodes, and then obtain the thickness change evaluation of the component corresponding to the kth node according to the influence of the kth node on all its upstream nodes.

[0107] Exemplarily, the representation method of the thickness change evaluation of the component corresponding to the kth node can be: Among them, Denotes the thickness change evaluation of the component corresponding to the kth node; Denotes the exponential function with the natural constant as the base. In this embodiment, The model realizes inverse proportional normalization; Denotes the total number of upstream nodes of the kth node; Denotes the influence coefficient of the kth node on the rth node upstream of it.

[0108] Through the above method, the thickness change evaluations of all nodes can be obtained. The smaller the thickness change evaluation of a node, the greater the influence of the node on the performance stability of the surrounding nodes. Therefore, when adjusting the thickness of the component corresponding to this node, the adjustment amplitude should be smaller.

[0109] In this embodiment, by analyzing in detail the number, load value, and number of nodes passed by each load transfer path, the influence degree of the thickness change of a certain component on other components can be accurately evaluated. This helps to identify key paths and potential risk points, ensuring the safety and economy of the design. Combining the diffusion coefficient and the influence coefficient, comprehensively evaluate the influence of the thickness change of the component on the performance stability of the entire structure. This systematic analysis method can avoid the global incoordination problem caused by local optimization and improve the safety of the overall structure.

[0110] In an embodiment of the present application, determining the adjusted thickness of each component based on the thickness change evaluation corresponding to each component includes: Obtain the current thickness and the minimum thickness requirement of each component; Compare the current thickness with the minimum thickness requirement to obtain a thickness difference; Based on the thickness difference and the thickness change evaluation, determine the adjusted thickness of each component.

[0111] Among them, the current thickness refers to the thickness of a component in the existing design or the initial design. This is based on the value recorded in the current engineering design document and reflects the current design state of the component.

[0112] Among them, the minimum thickness requirement is the minimum thickness value that each component must meet according to building codes, standards, and safety requirements. This value is usually determined by a structural engineer based on load analysis, material properties, and other factors to ensure the safety and durability of the structure.

[0113] Exemplarily, obtain the strength standard of each component by referring to relevant regulations, and obtain the minimum thickness requirement of each component in the current building model according to the force-bearing situation of each component in the BIM model. Then, adjust the thickness of the components corresponding to each node based on the thickness change evaluation.

[0114] Exemplarily, the adjusted thickness of the component corresponding to the kth node can be expressed as: Among them, represents the adjusted thickness of the component corresponding to the kth node; represents the current thickness of the component corresponding to the kth node; represents the minimum thickness requirement of the component corresponding to the kth node; represents the thickness change evaluation of the component corresponding to the kth node.

[0115] Among them, represents the thickness difference of the component corresponding to the kth node. The greater the thickness difference, the greater the adjusted thickness.

[0116] In this embodiment, by comparing the current thickness with the minimum thickness requirement in detail and combining the thickness change evaluation, it is possible to accurately identify which components can have their thickness adjusted while ensuring safety. This method avoids overly conservative designs and realizes the effective utilization of resources. When adjusting the thickness of components, the impact on other components is fully considered to ensure the safety and stability of the overall structure. This helps to prevent overall disharmony problems caused by local optimization and improves the safety factor of the project. Reasonably reducing unnecessary over-thick designs reduces the material usage and construction costs. For example, in the above example, appropriately reducing the thickness of columns and floors can save a large amount of concrete and steel, thus reducing the total project cost.

[0117] In an embodiment of the present application, optimizing the construction cost of the target building based on the adjusted thickness includes: Determine the material cost saved for each component according to the adjusted thickness; For the component with the largest saved material cost, adjust the thickness according to the adjusted thickness; Update the building information model according to the component with the adjusted thickness; For the updated building information model, perform iterative calculations to adjust the thickness and adjust the thickness of the components until the adjusted thickness of each component is less than a preset adjustment threshold.

[0118] The material cost saved for a component refers to the cost savings brought by the reduced material usage through adjusting the component thickness. This is usually calculated based on the current thickness, adjusted thickness of the component, and the unit price of the material.

[0119] When determining the material cost saved for each component according to the adjusted thickness, after determining the adjusted thickness of each component, calculate the change in its material usage and estimate the corresponding material cost savings accordingly.

[0120] When adjusting the thickness of the component with the largest saved material cost according to the adjusted thickness, those components that can bring the largest material cost savings through thickness adjustment can be preferentially selected for optimization adjustment to achieve significant cost reduction.

[0121] When updating the building information model (BIM) according to the component with the adjusted thickness, the adjusted thickness of the component can be updated to the BIM to ensure that all design documents and simulation analyses are based on the latest data.

[0122] When performing iterative calculations to adjust the thickness and adjust the thickness of the components for the updated building information model until the adjusted thickness of each component is less than a preset adjustment threshold, after each adjustment, recalculate and evaluate the structural performance, and repeat this process until the adjusted thickness change of all components reaches an acceptable small range (i.e., less than the preset adjustment threshold), thereby ensuring that the optimization process converges to the optimal solution.

[0123] Exemplarily, after obtaining the adjusted thickness of each component, calculate the material cost saved for each component according to the adjusted thickness of each component, select the component with the largest saved material cost, and modify its thickness. Update the modified thickness information into the BIM model, and update the change of the load condition in the current building model after adjusting the thickness of the component. Re-obtain the adjusted thickness of each component after adjusting one component, and select the component to be adjusted again. Multiple iterations can be performed to adjust the thicknesses of multiple components to control the cost. The preset adjustment threshold is 0.01 m. When the adjusted thicknesses of all components are less than 0.01 m, stop the iteration (at this time, the benefits of optimizing the thicknesses of all components are relatively low).

[0124] Exemplarily, after completing the iterative adjustment of the components, a cost table of the adjusted model can also be generated, which contains the cost details of each building material. By comparing the adjusted cost table with the initial cost table before adjustment, the optimization rate of each material can be obtained.

[0125] Exemplarily, the expression method of the cost optimization amount of Material A can be:[[]] Exemplarily, the expression method of the optimization rate of Material A can be:[[]] Mark the cost optimization amount and the optimization rate of each building material in the adjusted cost table, and record the cost optimization amount and the optimization rate as 0 for the unoptimized materials, then the electronic information-based construction project cost management can be realized.

[0126] In this embodiment, by calculating the material cost savings of each component in detail and preferentially adjusting the component with the largest material cost savings, the total project cost can be minimized to the greatest extent on the premise of ensuring structural safety. The iterative calculation method is adopted to gradually adjust the component thickness and re-evaluate the structural performance to ensure that the optimization process converges to the optimal solution. This method improves the design efficiency and reduces the time and workload of repeatedly modifying the design. After each adjustment of the thickness, update the relevant information in the BIM in a timely manner to ensure that all design documents and simulation analyses are based on the latest data. This dynamic update mechanism helps to improve the accuracy and reliability of the design.
