Description

Technical Field

[0001] The present invention relates to the technical field of electrical digital data processing of buildings, and in particular to a construction engineering cost management method and system based on electronic informationization. Background Art

[0002] Construction project cost management refers to a series of scientific management tasks such as forecasting, planning, controlling, accounting, analyzing and evaluating project costs at various stages of a construction project (including decision-making, design, bidding, construction and final acceptance). 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] Construction project cost management has always been a key issue in the construction industry, involving multiple aspects such as project budgeting, cost control, and settlement audits. With the maturity of computer, database, and communication technologies, particularly the application of cloud computing, big data, and artificial intelligence, the level of informatization in the construction industry has been significantly improved. For example, in cost management, the use of BIM (Building Information Modeling) based on electronic construction project information can achieve the simultaneous management of design changes and construction progress and costs, thereby more accurately predicting and controlling project costs.

[0004] Adjusting the thickness of components (the fundamental building blocks of buildings or structures) is a common optimization method for controlling construction costs in construction project cost management. For example, the thicker the floor slab, the higher the cost of materials like steel and concrete used in its construction. Furthermore, the thicker the slab, the greater its deadweight, which increases the load on supporting components like beams and columns, leading to a corresponding increase in their costs. Existing design methods typically use manual calculations and two-dimensional drawings to adjust the thickness of building components to control construction costs. However, this approach struggles with comprehensive structural analysis and optimization, resulting in inaccurate and incomplete designs for adjusting component thickness. The design fails to fully consider the impact of thickness adjustments on other components, creating challenges in balancing safety and cost efficiency.

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

[0069] The above section introduces the contents of an exemplary implementation environment for applying the technical solution of this application. Next, we will continue to introduce the construction project cost management method based on electronic informationization of this application.

[0070] In order to solve the problem of how to improve the balance between safety and economy in construction project cost management in the existing technology, the embodiments of this application respectively propose a construction project cost management method based on electronic informationization and a construction project cost management system based on electronic informationization. These embodiments will be described in detail below.

[0071] See also Figure 2 , Figure 2 A flow chart of a construction project cost management method based on electronic information technology provided by an embodiment of the present invention, which can be applied to Figure 1 It should be understood that the method can also be applied to other exemplary implementation environments and specifically executed by devices in other implementation environments, and this embodiment does not limit the implementation environment to which the method is applicable.

[0072] like Figure 2 As shown, in an exemplary embodiment, the construction project cost management method based on electronic information technology includes at least steps S210 to S240, which are described in detail as follows:

[0073] In step S210, a building information model corresponding to a target building is obtained, where the building information model is established based on engineering electronic information of the target building.

[0074] Among them, the target building refers to the specific construction project that requires cost management and optimization.

[0075] Among them, Building Information Modeling (BIM) refers to a three-dimensional building model built based on digital technology, which contains all the detailed information of the building, such as geometric shape, material properties, etc.

[0076] Among them, engineering electronic information refers to the data and documents used to build BIM, including but not limited to design drawings, construction plans, bills of materials, etc.

[0077] In step S220, the load transfer paths and load values ​​in the building information model are extracted, and based on the load transfer paths and load values, a load transfer tree diagram of multiple components in the target building is established.

[0078] Among them, the load transfer path describes the force transfer route between different components in the building structure.

[0079] Among them, the load value is the quantitative value of various forces applied to the building structure, such as wind force, snow pressure, etc.

[0080] Among them, components refer to the basic units that constitute the building structure, such as beams, columns, and slabs.

[0081] Among them, the load transfer tree diagram is a visual tool used to show how the load is transferred through various components in the building structure.

[0082] In step S230, the thickness change of the component corresponding to each node in the load transfer tree diagram is analyzed, and the impact on the components corresponding to other nodes within a preset range is analyzed to determine the thickness change evaluation corresponding to each component.

[0083] A node is a point in the load transfer tree diagram, representing a connection point between one or more components.

[0084] Among them, the thickness change of a component refers to the change in the thickness of a component, which may affect its load-bearing capacity and cost.

[0085] Among them, thickness change evaluation is to assess the impact of thickness changes of a certain component on the safety and economy of the entire building structure.

[0086] In step S240, based on the thickness change evaluation corresponding to each of the components, the adjusted thickness of each of the components is determined, and the construction cost of the target building is optimized based on the adjusted thickness.

[0087] Among them, the adjusted thickness of the component is the optimal thickness determined based on the thickness change evaluation.

[0088] For example, consider a multi-story office building project. First, a BIM is created for the office building, including electronic engineering information such as design drawings, material specifications, and other information for all floors. Next, the load transfer paths and load values ​​for each floor slab and column are extracted from the BIM, and a load transfer tree diagram is drawn based on this information. Next, an analysis is performed to determine how changes in the thickness of the component corresponding to each node in the tree diagram (for example, a column) affect surrounding components (such as adjacent floor slabs). If increasing the thickness of a column can reduce stress concentration in other components but increase costs, a comprehensive evaluation will be conducted to determine the optimal thickness. Ultimately, based on these adjusted thicknesses, the cost of the entire building is optimized.

[0089] As can be seen from the above steps S210 to S240, in the solution proposed in this embodiment, by obtaining a building information model established based on engineering electronic information, various detailed information of the building, including geometric shape, material properties, load conditions, etc., can be integrated; 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 the components can be intuitively displayed, which not only improves the accuracy of the analysis but also facilitates the identification of critical 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; based on the thickness change evaluation, the optimal thickness adjustment scheme is selected to minimize material cost and construction cost, reduce unnecessary over-thickness design, avoid waste of resources, and ensure that the structural performance meets the requirements.

[0090] In one 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;

[0091] The building information model includes building model geometry information, component performance data, construction methods, material types, and procurement information.

[0092] Among them, building design dimensions are the physical size parameters of a building, including but not limited to length, width, height, etc., which are used to define the specific scale of the building; component types are used to describe different types of structural units in a building, such as beams, columns, walls, slabs, etc.; component specifications are specific descriptions of the dimensions and technical requirements of each component, such as cross-sectional dimensions and reinforcement configuration; component quantity refers to the number of components of a specific type, which helps quantify the materials required and costs for a building; material specifications are specific technical standards for building materials, such as concrete strength grade and steel type; material unit price is the price per unit volume or weight of material, which is used to calculate the project budget;

[0093] Among them, the building model geometry information is the three-dimensional geometric data in BIM, which includes the building's appearance and internal space layout; the component performance data is the performance index of each component in terms of force, such as bearing capacity, durability, etc.; the construction method is a technical plan that describes how to implement the construction project, including the construction sequence, process flow, etc.; the material type is a list of all different types of materials used in the project, such as concrete, steel, glass, etc.; procurement information is related information such as material suppliers, delivery time, and transportation methods.

[0094] For example, imagine designing a bridge. First, the design dimensions (e.g., total length, span, etc.) of the bridge must be determined, along with the types of components (e.g., piers, decks) and their specifications (e.g., cross-sectional dimensions, reinforcement layout). Next, the number of components must be counted, and the material specifications (e.g., concrete strength grade, steel grade) and unit prices determined. Based on this electronic engineering information, a detailed BIM can be constructed, including precise building model geometry, component performance data (e.g., compressive strength), construction methods (e.g., cast-in-place or prefabrication), material types (e.g., cement, sandstone, rebar), and procurement information (e.g., supplier, expected delivery date).

[0095] In this embodiment, by thoroughly recording information such as the building design dimensions, component types, specifications, and quantities, fine control of the construction project is achieved, which helps to improve work efficiency and accuracy; by clarifying material specifications and unit prices, combined with the number of components, the direct cost of the project can be accurately calculated, facilitating cost control and optimization; through detailed building model geometry information and component performance data, potential risk points can be identified early, preventive measures can be taken, and the possibility of later modifications and rework can be reduced; a comprehensive and consistent information platform is provided to facilitate communication and collaboration between different professional teams, reducing misunderstandings and conflicts; reasonable planning of material types and procurement information promotes the effective use of resources, conforms to the concept of green building, and promotes sustainable development; based on detailed data support, management can make more scientific and reasonable decisions to ensure the smooth progress of the project.

[0096] In one embodiment of the present application, extracting the load transfer paths and load values ​​from the building information model and establishing a load transfer tree diagram for multiple components in the target building based on the load transfer paths and load values ​​includes:

[0097] Performing load analysis on the building information model using a pre-configured finite element analysis module to obtain load transfer paths in the plurality of components and load values ​​on the load transfer paths;

[0098] The load transfer tree diagram is established by taking each component as a node, the load transfer path between the nodes as a directed edge, the dead weight of the component as the value of the node, and the load value as the weight of the directed edge, wherein the order of the nodes corresponds to the order of the components from top to bottom in the building information model.

[0099] In construction projects, when adjusting thickness or removing components to control construction costs, the load borne by the components is crucial to determining whether thickness adjustments can be made. Adjusting the thickness of critical load-bearing components can significantly impact other components, even compromising the building's safety. Therefore, the load conditions of each component in the current building must be determined.

[0100] The Finite Element Analysis module is a numerical simulation tool used to perform mechanical analysis on structures. It divides the structure into multiple small units (i.e., "finite elements") and calculates parameters such as stress and strain for each unit, thereby evaluating the behavior of the entire structure.

[0101] Among them, load analysis is a specific type of analysis performed in the finite element analysis module, which is used to determine the response of each component in the building structure under different loads, such as stress distribution, deformation, etc.

[0102] In graph theory, a directed edge represents a connection between two nodes and has a directionality. In this embodiment, a directed edge represents the direction and path of load transfer from one component to another.

[0103] Among them, the deadweight of a component refers to the weight of the component itself, which is a constant load that must be considered in structural design.

[0104] Among them, the value of the node is in the load transfer tree diagram. The value of the node can represent certain properties or states of the component corresponding to the node, such as self-weight.

[0105] Among them, the weight of the directed edge is in graph theory. The weight of the edge usually represents a certain metric, which here refers to the load value on the load transfer path.

[0106] 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, the preset finite element analysis tool can be used to analyze the structure in the BIM, identify how the load is transferred between the various components, and calculate the specific load value on each transfer path.

[0107] For example, suppose a multi-story residential building is being designed. Figure 3 , Figure 3 This is a schematic diagram of building load transfer provided by an embodiment of the present invention. Figure 3 As shown in the figure, the load transfer for this multi-story residential building involves components such as waterproofing, cast-in-place concrete roof panels, roof beams, and frame columns. The load relationships between these components are indicated by arrows. To ensure the safety and economic efficiency of the structure, a detailed analysis of the load transfer paths is required. First, a 3D model of the residential building is created in BIM software, including the design dimensions and material specifications of all floors, beams, columns, walls, and other components. Then, a preconfigured finite element analysis module (such as ANSYS or SAP2000) is integrated into the BIM environment. During load analysis, the various loads acting on the building are defined, such as dead load (self-weight), live load (people, furniture, etc.), wind load, and snow load. The finite element analysis module is then launched to perform load analysis on the model, calculating the stress and deformation of each component under these loads. The load transfer paths and their corresponding load values ​​are also generated. When establishing a load transfer tree diagram, each component, such as a column, beam, or floor slab, is considered a node. Based on the results of finite element analysis, the load transfer path is treated as a directed edge, and each edge is assigned a specific load value (i.e., weight). For example, a column transfers a load of 500 kN to the foundation below it. The nodes are arranged from top to bottom in the building information model to form a complete load transfer tree diagram.

[0108] In this embodiment, the finite element analysis module can accurately simulate and analyze the load transfer path in the building structure, avoiding the errors that may be caused 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 critical paths and potential risk points, facilitating optimized design; the integration of the finite element analysis module through the BIM platform promotes efficient collaboration between different professional teams (such as structural engineers, architects, and construction managers), reducing communication barriers and information loss; by accurately analyzing the load conditions of each component, the component thickness and other design parameters can be reasonably adjusted while ensuring structural safety, thereby achieving effective cost control.

[0109] In one embodiment of the present application, analyzing the thickness change of a component corresponding to each node in the load transfer tree diagram and its impact on components corresponding to other nodes within a preset range to determine a thickness change evaluation corresponding to each component includes:

[0110] Analyzing the association relationship between the component corresponding to each node 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;

[0111] According to the position of the component corresponding to each node in the new load transfer tree diagram and the number of all components connected by the component corresponding to each node, the influence range of the thickness change of the component corresponding to the node on the components corresponding to other nodes is analyzed to obtain the diffusion coefficient corresponding to each node;

[0112] According to the load transfer conditions of the components corresponding to each node in the new load transfer tree diagram and the diffusion coefficient corresponding to each node, the influence of the thickness change of the component corresponding to the node on the performance stability of the components corresponding to other nodes is analyzed, and an evaluation of the thickness change of the component corresponding to each node is obtained.

[0113] Due to the varying relationships between components and the loads they bear, the degree of adjustment available for thickness adjustment varies. For example, adjusting the thickness of a connecting component that connects multiple components or bears loads from multiple sources can affect the state of multiple other components, requiring adjustments to their dimensions and other properties. This significant change increases design costs. Therefore, when considering thickness adjustments, prioritize components that are interconnected with multiple components to avoid excessive design cost increases.

[0114] The thickness direction refers to the measurement of the component in the direction of its smallest dimension, usually perpendicular to the surface of the component. For example, the thickness direction of a floor slab is perpendicular to its plane.

[0115] The association 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 component and other components directly or indirectly connected in the thickness direction, for example, the relationship between a floor slab and its supporting beams.

[0116] The nodes are merged according to the association relationship. By analyzing the association relationship between components, similar or closely related nodes can be merged into one node, thereby simplifying the load transfer tree diagram and making subsequent analysis more efficient.

[0117] 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, which represents 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.).

[0118] 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 the component in the network.

[0119] 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 influence range of the thickness change of a component on other components, which can be quantified by the diffusion coefficient.

[0120] Among them, the diffusion coefficient corresponding to the node is a numerical indicator used to measure the degree of influence of the thickness change of the component corresponding to a node on other nodes. The larger the value, the wider the influence range.

[0121] 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.

[0122] 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 be used to analyze how the thickness change of a component affects the performance indicators such as the bearing capacity and deformation of other components, and evaluate the stability of the overall structure.

[0123] For example, suppose you are designing a multi-story office building and want to optimize construction costs by adjusting the thickness of certain components. Each floor of this multi-story office building has several columns and floor slabs. Use the Finite Element Analysis module to generate an initial load transfer tree diagram, where each node represents a component (such as a column or floor slab) and edges represent load transfer paths. Analyze the relationship between the component corresponding to each node and the other components it connects to along the thickness direction. For example, consider the relationship between a floor slab on a particular floor and the four columns supporting it. If these columns have similar functions and similar load transfer paths, they can be merged into a single node to simplify the tree diagram. Based on this simplified load transfer tree diagram, calculate the location of the component corresponding to each node and the number of components it connects to. For example, the top floor slab is connected to four columns, each of which is connected to the floor slab on the next floor. Based on this information, calculate the diffusion coefficient for each node to assess the impact of the thickness change. Detailed analysis is performed on the load transfer behavior of the component corresponding to each node to determine its role in the load transfer path. For example, what load does the top floor slab transfer to the four columns, and what load does these columns then transfer to the next floor slab? Imagine increasing the thickness of the top floor slab by 10%. Recalculate the load transfer path and analyze the impact of this thickness change on the performance and stability of other components at the nodes (such as columns and the next floor slab). For example, increasing the floor slab thickness will increase the load on the columns, and the cross-sectional dimensions of the columns may need to be adjusted to ensure their load-bearing capacity.

[0124] In this example, by analyzing the impact of component thickness changes on other components, it is possible to accurately identify which components' thickness adjustments will have a significant impact on the overall structure, allowing for targeted design optimization. Using diffusion coefficients and load transfer, a comprehensive assessment of the impact of thickness changes on the entire building structure is performed, ensuring that thickness adjustments do not introduce new risks. Nodes with similar functions or close connections are merged to simplify the load transfer tree, reducing computational complexity and improving analysis efficiency.

[0125] In one embodiment of the present application, analyzing the association relationship between the component corresponding to each node 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 includes:

[0126] For a component corresponding to any of the nodes, obtain the number of load source components between the component and other components connected in the thickness direction, and the number of load transfer components between the component and other components connected in the thickness direction;

[0127] Comparing the number of the load source components with the number of the load transfer components to obtain a correlation degree, wherein the correlation degree is used to indicate the correlation relationship;

[0128] Two components whose correlation degree is greater than a preset correlation degree threshold are merged to obtain the new load transfer tree diagram.

[0129] When constructing the load transfer tree, each component is considered a node. However, in real buildings, many components are not independent. For each component connected to its thickness, a change in the thickness of one component can cause changes in the thickness of other components as well. Therefore, when considering thickness adjustments, the associated components must be considered together. The thickness relationships of each component are analyzed to merge strongly associated component nodes for easier analysis.

[0130] The number of load source components refers to the number of other components directly or indirectly connected to the component corresponding to a node in the thickness direction that transfer load to the component. For example, the number of load source components that a column receives from the floor slab and wall.

[0131] The number of load-transferring members refers to the number of other members that a node's corresponding member directly or indirectly connects to in the thickness direction, transferring the load. For example, a column transfers load to the foundation and other supporting structures.

[0132] The degree of correlation is a numerical indicator calculated by comparing the number of load-generating components with the number of load-transmitting components. It measures the closeness of the relationship between two components. The higher the degree of correlation, the stronger the interdependence between the two components.

[0133] The preset correlation threshold is a pre-set value used to determine which components are sufficiently correlated to be merged into a single node. This threshold is typically determined based on specific project requirements and empirical data.

[0134] For example, for two connected components, the more consistent the loads they receive at the previous level and the loads applied to the next level, the more likely a change in the thickness of one component will also affect the thickness of the other, indicating a strong correlation between the two components. When analyzing load changes caused by thickness changes, isolating strongly correlated components can lead to inconsistent changes, which is inconsistent with actual conditions. Therefore, taking the i-th component as an example, we obtain each component connected to it along its thickness and analyze their correlation.

[0135] For example, the degree of association between the i-th component and the j-th component connected to it in the thickness direction may be expressed as follows:

[0136]

[0137] in, Indicates the degree of association between the i-th component and the j-th component connected to it in the thickness direction; Represents the Sigmoid function, which is used for linear normalization in this embodiment; It represents the number of loads from the same component that the i-th component and the j-th component connected to it in the thickness direction receive (i.e., the number of components with the same load source); The number of load source components representing all sources of the load from the i-th component to the j-th component connected to it in the thickness direction. The same component is counted only once. It represents the number of loads transferred from the i-th component to the j-th component connected to it in the thickness direction to the next-level identical components (i.e., the number of load-transferring components with the same transfer target); It represents the number of load transfer members with the same transfer target for the i-th member and the j-th member connected to it in the thickness direction; and The 1 is added at the end to prevent the denominator from being zero.

[0138] in, and It can represent the association relationship between the i-th component and the j-th component connected to it in the thickness direction. When these two values ​​are larger, it means that the i-th component is strongly associated with the j-th component connected to it in the thickness direction.

[0139] For example, a preset correlation threshold of 0.8 is used. Two components with a correlation greater than 0.8 are strongly correlated. All strongly correlated component nodes are merged, and the load transfer diagram for the current building is updated. This merging of strongly correlated component nodes avoids inconsistencies and ensures analysis accuracy.

[0140] In this embodiment, by merging highly correlated component nodes, the load transfer tree diagram can be significantly simplified, reducing computational complexity and workload, and improving analysis efficiency. The merged nodes more accurately reflect the interactions between components in the actual structure, avoiding errors caused by overly detailed divisions and improving the accuracy of the overall analysis. The simplified load transfer tree diagram makes it easier to identify critical paths and potential risk points, helping engineers make more scientific and reasonable thickness adjustment decisions, ensuring the safety and economic efficiency of the structure.

[0141] In one embodiment of the present application, the diffusion coefficient corresponding to each node is obtained by analyzing the influence range of the thickness change of the component corresponding to the node on the components corresponding to other nodes based on the position of the component corresponding to each node in the new load transfer tree diagram and the number of all components connected by the component corresponding to each node, including:

[0142] For any of the nodes, taking all nodes with zero in-degree in the new load transfer tree as starting points, and determining the number of nodes traversed by all paths between each starting point and the node;

[0143] The maximum number of nodes is used as the maximum depth of the node, and the maximum depth is used to indicate the position of the component corresponding to the node;

[0144] The diffusion coefficient corresponding to each node is determined by combining the maximum depth and the number of all components connected to the component corresponding to the node.

[0145] When adjusting component thickness to control construction costs, components with minimal impact on other components are often preferred. A node with a greater number of connected components indicates a more complex structure. A node located further downstream in the load transfer diagram indicates a more complex load and a lower priority for the component being adjusted. The diffusion coefficient for each node can be determined by the number of components connected to the node and its position in the load transfer diagram.

[0146] In graph theory, the in-degree of a node refers to the number of edges pointing to that node. In a load transfer tree diagram, a node with an in-degree of zero indicates that no other component directly transfers load to it.

[0147] The starting point refers to all nodes in the load transfer tree with zero in-degree. These nodes usually represent the initial load sources (such as floors, roofs, etc.).

[0148] The number of nodes traversed by all paths from the starting point to the node is the total number of nodes passed by all possible paths from each starting point to the target node. This value is used to calculate the maximum depth.

[0149] The maximum depth is the number of nodes in the path from the starting point to the target node that passes through the largest number of nodes. It reflects the relative position of the node in the entire structure.

[0150] Among them, the diffusion coefficient is a numerical indicator used to measure the impact of the thickness change of a component corresponding to a node on other nodes. It can be determined by combining the maximum depth and the number of all connected components.

[0151] For example, taking the kth node as an example, first determine the kth node's position in the load transfer diagram. Starting from all nodes with in-degree 0 in the load transfer diagram, calculate the number of nodes required to traverse all paths from each starting point to the kth node (if no path exists between the starting point and the kth node, this is recorded as -1). The maximum value of all node counts is taken as the maximum depth of the kth node. A smaller maximum depth indicates that the kth node is further upstream in the load transfer diagram. Then, the diffusion coefficient is calculated based on the number of components connected to the component corresponding to the node.

[0152] For example, the diffusion coefficient of the kth node may be expressed as:

[0153]

[0154] in, is the diffusion coefficient of the kth node; represents the linear normalization function; Indicates the maximum depth of the k-th node; Represents the number of all components connected to the component corresponding to the kth node.

[0155] in, The size of reflects the impact range of the surrounding components of each node when the thickness of the component corresponding to the node changes. The smaller the value of , the smaller the influence range of the kth node.

[0156] In this example, by calculating the maximum depth and diffusion coefficient, we can accurately assess the extent to which a component's thickness change affects the entire structure. This helps identify critical paths and potential risk points, ensuring the safety and cost-effectiveness of the design. This provides a quantitative method for evaluating the impact of component thickness changes, helping engineers make scientifically sound optimization decisions. For example, while ensuring structural safety, we can rationally adjust component thickness to reduce material costs.

[0157] In one embodiment of the present application, the load transfer status of the component corresponding to each node in the new load transfer tree diagram and the diffusion coefficient corresponding to each node are analyzed to determine the effect of the thickness change of the component corresponding to the node on the performance stability of the components corresponding to other nodes, thereby obtaining the thickness change evaluation of the component corresponding to each node, including:

[0158] For any node in the new load transfer tree diagram, obtain all load transfer paths where the node is located;

[0159] Determine the number of load transfer paths, load values, and the number of nodes passed between the node and any upstream node based on all the load transfer paths;

[0160] Determine the influence coefficient of the node on any of the upstream nodes based on the number of load transfer paths, load values, number of nodes passed through, and diffusion coefficients corresponding to each of the nodes. The influence coefficient indicates the influence of a thickness change of a component corresponding to the node on the performance stability of the component corresponding to any of the upstream nodes.

[0161] Combined with the influence coefficient of the node on all the upstream nodes, the thickness change evaluation of the component corresponding to each node is determined.

[0162] When a component's thickness changes, it can also affect the performance stability of adjacent components along the load transfer path. Adjacent components can further diffuse this impact to their neighbors, creating a butterfly effect. When a component's thickness changes, the resulting performance impact diffuses from the node where the thickness change occurs, affecting all nodes along the load transfer path. The thickness change evaluation for each node can be derived based on the load transfer status and diffusion coefficient of each node.

[0163] The number of load transfer paths refers to the number of all possible load transfer paths from a node to any of its upstream nodes. Each path represents the specific route by which the load is transferred from one component to another.

[0164] The load value is the specific load value on each load transfer path, indicating the magnitude of the force transmitted along that path. These load values ​​are usually calculated by the finite element analysis module.

[0165] The number of nodes passed is the number of all nodes passed along a path from a node to any of its upstream nodes. This value reflects the number of intermediate components involved in the load transfer process.

[0166] For example, all load transfer paths where the kth node is located are obtained, and taking the kth node to the rth node upstream as an example, the influence coefficient of the kth node on the rth node upstream is analyzed. The influence coefficient of the kth node on the rth node upstream can be expressed as:

[0167]

[0168] in, represents the influence coefficient of the kth node on its upstream rth node; Represents the Sigmoid function, which is used for linear normalization in this embodiment; represents the number of load transfer paths between the kth node and the rth node; Indicates that the kth node receives the Load values ​​on the load transfer paths; Indicates the number of nodes between the kth node and the rth node The number of nodes that the load transfer path passes through (the calculation of the number of nodes needs to include the kth node but not the rth node); Indicates the number of nodes between the kth node and the rth node The diffusion coefficient of the h-th node passed by the path, where h=0 represents the k-th node.

[0169] in, The larger the value, the greater the load. When the thickness of a node changes, it is more likely to affect the performance stability of the components corresponding to other nodes.

[0170] 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 based on the influence of the kth node on all its upstream nodes.

[0171] For example, the thickness variation evaluation of the component corresponding to the kth node may be expressed as follows:

[0172]

[0173] in, represents the thickness change evaluation of the component corresponding to the kth node; Represents an exponential function with a natural constant as the base. In this embodiment, The model implements inverse proportional normalization; Indicates the total number of upstream nodes of the k-th node; Represents the influence coefficient of the kth node on its upstream rth node.

[0174] Through the above method, the thickness change evaluation of all nodes can be obtained. The smaller the thickness change evaluation of a node, the greater the impact of the node on the performance stability of the surrounding nodes. Therefore, when adjusting the thickness of the component corresponding to the node, the adjustment range should be smaller.

[0175] In this example, by analyzing the number of load transfer paths, load values, and the number of nodes passed through, we can accurately assess the impact of a component's thickness change on other components. This helps identify critical paths and potential risk points, ensuring the safety and cost-effectiveness of the design. Combining the diffusion coefficient and influence coefficient allows for a comprehensive assessment of the impact of component thickness changes on the performance and stability of the entire structure. This systematic analysis approach avoids global inconsistencies caused by local optimization and improves the safety of the overall structure.

[0176] In one embodiment of the present application, determining the adjusted thickness of each component based on the thickness change evaluation corresponding to each component includes:

[0177] Obtaining the current thickness and minimum thickness requirement of each component;

[0178] Comparing the current thickness with the minimum thickness requirement to obtain a thickness difference;

[0179] The adjusted thickness of each component is determined based on the thickness difference and the thickness change evaluation.

[0180] The current thickness refers to the thickness of the component in the existing or initial design. This is based on the value recorded in the current engineering design file and reflects the current design status of the component.

[0181] The minimum thickness requirement is the minimum thickness that each component must meet based on building codes, standards, and safety requirements. This value is typically determined by structural engineers based on load analysis, material properties, and other factors to ensure the safety and durability of the structure.

[0182] For example, the strength standards for each component are obtained by consulting relevant regulations. Based on the stress conditions of each component in the BIM model, the minimum thickness requirement for each component in the current building model is determined. Then, based on the thickness variation evaluation, the thickness of the component corresponding to each node is adjusted.

[0183] For example, the expression of the adjusted thickness of the component corresponding to the kth node may be:

[0184]

[0185] in, represents the adjusted thickness of the component corresponding to the kth node; Indicates the current thickness of the component corresponding to the kth node; Indicates the minimum thickness requirement of the component corresponding to the kth node; Indicates the thickness change evaluation of the component corresponding to the kth node.

[0186] in, It represents the thickness difference of the component corresponding to the kth node. The larger the thickness difference, the larger the adjusted thickness.

[0187] In this embodiment, by comparing the current thickness with the minimum thickness requirement in detail and combining it with 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 design and achieves efficient use of resources. When adjusting the thickness of a component, its impact on other components is fully considered to ensure the safety and stability of the overall structure. This helps to prevent overall incoordination problems caused by local optimization and improves the safety factor of the project. Reasonable reduction of unnecessary over-thickness design reduces material usage and construction costs. For example, in the above example, appropriately reducing the thickness of the columns and floor slabs can save a lot of concrete and steel bars, thereby reducing the total cost of the project.

[0188] In one embodiment of the present application, the optimizing the construction cost of the target building based on the adjusted thickness includes:

[0189] Determining the material cost saved for each component according to the adjusted thickness;

[0190] For the component with the greatest material cost savings, the thickness is adjusted according to the thickness adjustment;

[0191] updating the building information model according to the thickness-adjusted component;

[0192] For the updated building information model, iterative calculation is performed to adjust the thickness, and the thickness of the components is adjusted until the adjusted thickness of each component is less than a preset adjustment threshold.

[0193] The material cost savings for a component refer to the cost savings from reducing material usage by adjusting the component thickness. This is usually calculated based on the component's current thickness, the adjusted thickness, and the unit price of the material.

[0194] Wherein, when determining the material cost savings of each component according to the adjusted thickness, after determining the adjusted thickness of each component, the change in its material usage is calculated, and the corresponding material cost savings are estimated accordingly.

[0195] Among them, for components that save the most material costs, when adjusting the thickness according to the thickness adjustment, those components that can bring the greatest material cost savings by adjusting the thickness can be preferentially selected for optimization adjustment to achieve significant cost reduction.

[0196] When updating the building information model (BIM) based on the components with adjusted thickness, the adjusted component thickness can be updated in the BIM, ensuring that all design files and simulation analyses are based on the latest data.

[0197] The updated building information model is iteratively calculated and adjusted for thickness, and the thickness of the components is adjusted until the adjusted thickness of each component is less than a preset adjustment threshold. After each adjustment, the structural performance is recalculated and evaluated. This process is repeated until the adjusted thickness 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.

[0198] Exemplarily, after obtaining the adjusted thickness of each component, the material cost saved for each component is calculated based on the adjusted thickness of each component, and the component with the largest material cost savings is selected to modify its thickness. The modified thickness information is updated to the BIM model, and the changes in the load conditions in the current building model after adjusting the thickness of the component are updated. The adjusted thickness of each component after adjusting a component is re-obtained, and the component to be adjusted is selected again. Multiple iterations can be performed to adjust the thickness of multiple components to control costs. The preset adjustment threshold is 0.01m. When the adjusted thickness of all components is less than 0.01m, the iteration is stopped (the benefits of optimizing the thickness of all components are low at this time).

[0199] For example, after completing the iterative adjustment of the components, a cost table of the adjusted model can be generated, which includes the cost details of each building material. By comparing the adjusted cost table with the initial cost table before the adjustment, the optimization rate of each material can be obtained.

[0200] For example, the cost optimization amount of material A may be expressed as follows:

[0201]

[0202] For example, the optimization rate of material A can be expressed as:

[0203]

[0204] Mark the cost optimization amount and optimization rate of each building material in the adjusted cost table, and record the cost optimization amount and optimization rate of unoptimized materials as 0, so that construction project cost management based on electronic information can be achieved.

[0205] In this example, by calculating the material cost savings for each component in detail and prioritizing the components with the greatest material cost savings, the total project cost can be minimized while ensuring structural safety. An iterative calculation method is used to gradually adjust component thicknesses and reassess structural performance, ensuring that the optimization process converges to the optimal solution. This approach improves design efficiency and reduces the time and effort required for repeated design revisions. After each thickness adjustment, the relevant information in the BIM is promptly updated to ensure that all design files and simulation analyses are based on the latest data. This dynamic update mechanism helps improve design accuracy and reliability.
