Description

Technical Field

[0001] This application relates to the technical field of load-bearing engineering projects for flower basket scaffolding, and more specifically, to a method and system for analyzing the load-bearing characteristics and deformation of flower basket scaffolding. Background Technology

[0002] Basket scaffolding is a common temporary support structure in building construction, widely used in high-rise building construction. However, existing technologies for stress analysis and deformation control of basket scaffolding still have shortcomings. They essentially do not address the system's stress characteristics and deformation analysis methods. Therefore, this invention aims to provide a comprehensive analysis method and system for optimizing the design and use of basket scaffolding. Summary of the Invention

[0003] This invention aims to provide a method and system for analyzing the stress characteristics and deformation of a flower basket scaffold. By establishing a three-dimensional finite element model and combining the load and boundary conditions of the actual working conditions, the method performs accurate stress and deformation analysis on the scaffold and optimizes the scaffold structure design based on the analysis results. This solves the problem that although existing technologies have proposed adjustable structures, they have not addressed the system's stress characteristics and deformation analysis methods.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A method for analyzing the stress characteristics and deformation of a flower basket scaffold, comprising the following steps: S1: Establish a three-dimensional finite element model of the flower basket scaffolding, including cantilever steel beams, diagonal tie rods, flower basket bolts, and anchor points; S2: Apply loads and boundary conditions according to the actual working conditions; S3: Calculate the stress distribution and deformation of each component through finite element analysis; S4: Optimize the scaffolding structure design based on the calculation results; In this process, based on the actual dimensions, material properties (such as elastic modulus and Poisson's ratio) and support conditions of the cantilever steel beam, a finite element model of the cantilever steel beam is generated using professional finite element modeling software (such as ANSYS and ABAQUS). This model needs to accurately simulate the structural characteristics of the cantilever steel beam, including its cross-sectional shape, dimensions, and connection methods.

[0005] Diagonal tie rods are crucial load-bearing components in basket scaffolding. When modeling them, factors such as length, cross-sectional area, material properties, and connection locations need to be considered. Finite element method (FEM) software can be used to generate FEM models of the tie rods and simulate their mechanical behavior under load.

[0006] Turnbuckles are important adjustment components in scaffolding, and their modeling is equally crucial. A corresponding finite element model needs to be generated based on the turnbuckle's geometry, material properties, and connection method. This model must be able to simulate the turnbuckle's adjustment function and mechanical behavior under stress.

[0007] Anchorage points are critical components connecting scaffolding to buildings or other structures. During modeling, it's essential to accurately simulate the location of anchorage points, constraints (such as fixed-end constraints, hinged-end constraints, etc.), and connection methods. This helps ensure the accuracy and reliability of the finite element analysis.

[0008] Preferably, in step S1, the stress calculation formula for the cantilever steel beam is: Where σ is the stress of the cantilevered steel beam, M is the bending moment, W is the section modulus, F is the tension of the tie rod, L is the cantilever length, E is the elastic modulus of the material, and I is the moment of inertia of the section. On the other hand, in the case of cantilever beams, since one end is fixed and the other end is freely extended, they will be subjected to bending moment, resulting in stress in the beam.

[0009] For a cantilevered steel beam with a rectangular cross-section, the formula for calculating its normal stress (bending stress) can be expressed as: in: It is the normal stress at a point on the beam cross section; It is the bending moment at the section where that point is located; It is the distance from that point to the neutral axis of the beam (in a rectangular section, this is the distance from the bottom or top of the beam to the neutral axis, depending on whether you are considering the tension zone or the compression zone). It is the moment of inertia of the beam section. For a rectangular section, its calculation formula is: ,in It is the width of the cross section. It is the height of the cross section.

[0010] However, in the case of cantilever beams, since the bending moment varies along the beam's length (especially in the cantilever section), more complex analyses are usually required to determine the bending moment distribution along the beam's length. This typically involves static analysis in structural mechanics, which may require the use of finite element methods or other numerical methods to obtain accurate results.

[0011] In addition, for steel beams, the yield strength of the material and other material-related properties must be considered to ensure that the design meets safety requirements.

[0012] In practical applications, engineers typically use specialized structural analysis software or tables and diagrams in manuals to assist in the calculation and design of cantilever steel beams. These tools provide simplified methods based on extensive testing and experience, enabling rapid and accurate assessment of beam stress and deformation.

[0013] Therefore, in summary It is a relatively good calculation method, taking into account multiple aspects. However, in practical applications, multiple calculation methods are used in combination. This is just a relatively preferred choice.

[0014] Preferably, in step S3, the formula for calculating the deformation of the tie rod is: Where ΔL is the deformation of the tie rod, F is the tension, L is the length of the tie rod, A is the cross-sectional area, E is the elastic modulus of the material, α is the coefficient of thermal expansion of the material, ΔT is the temperature change, and ν is Poisson's ratio.

[0015] In step S2, the loads include vertical loads, horizontal loads, and wind loads, and the boundary conditions include fixed-end constraints and hinged-end constraints.

[0016] Vertical loads mainly include the weight of the scaffold itself, the weight of materials placed on the scaffold, and the weight of construction workers and equipment.

[0017] These loads typically act vertically on the various components of the scaffolding and are the main factors causing vertical deformation and stress in the scaffolding.

[0018] Horizontal loads come from multiple sources, such as horizontal thrust during construction and horizontal forces caused by wind loads. Horizontal loads are crucial to the stability of scaffolding, especially in high-rise buildings or complex construction environments.

[0019] Wind load is an indispensable factor in scaffolding design, especially in open areas or areas with high wind speeds. The magnitude and direction of wind load may change over time, so the influence of dynamic wind load usually needs to be considered when performing finite element analysis.

[0020] In some embodiments, we actually calculate the self-weight of the flower basket scaffolding by using the density and volume of the flower basket scaffolding material in practice; Determine the load on construction personnel and materials based on the actual construction situation; Through formula Calculate the wind load; where P is the wind load. Let z be the wind vibration coefficient at a height of z. Let z be the wind pressure height variation coefficient at a height of z. The wind load shape coefficient for the flower basket scaffolding; This is the basic wind pressure.

[0021] Fixed-end restraints are typically applied to the bottom of scaffolding or at points where it connects to other structures.

[0022] At the fixed end, the displacement of the scaffolding is completely restricted, meaning that no movement or rotation in any direction is allowed.

[0023] Hinged end constraints allow the scaffolding to rotate in a specific direction, but restrict movement in other directions.

[0024] This type of constraint is typically applied to the connection points between the scaffolding and other structures, or to certain connection points within the scaffolding.

[0025] In finite element analysis, it is necessary to accurately simulate these loads and boundary conditions. This involves applying appropriate forces and constraints to the finite element model and setting reasonable analysis parameters. By accurately simulating these conditions, the accuracy and reliability of the analysis results can be ensured, thus providing strong support for the structural design of scaffolding.

[0026] In step S4, the design optimization includes adjusting the angle of the tie rod, increasing the number of anchor points, and optimizing the cross-sectional dimensions of the cantilever steel beam. Adjusting the angle of the tie rods has a significant impact on the stability and load-bearing capacity of the scaffolding. The angle of the tie rod determines its stress state; a proper angle allows the tie rod to more effectively bear and transfer loads.

[0027] By adjusting the angle of the diagonal tie rods, the stress state can be optimized, improving the overall stability and load-bearing capacity of the scaffolding. This helps reduce deformation and stress concentration during the stress process, thereby extending its service life.

[0028] In practice, the optimal angle of the diagonal braces needs to be determined through calculation and simulation based on the specific structure and stress conditions of the scaffolding. This angle is then adjusted by changing the connection points of the diagonal braces or adding additional connectors.

[0029] Increasing the number of anchor points is another effective way to improve the stability and load-bearing capacity of scaffolding. Anchor points are key components that connect scaffolding to buildings or other structures, and their number and location have a significant impact on the overall performance of the scaffolding.

[0030] Increasing the number of anchor points can more effectively transfer the load of the scaffolding to the building or other structures, thereby improving its stability. At the same time, this also helps to reduce deformation and displacement of the scaffolding during stress, ensuring its safety during use.

[0031] When increasing the number of anchor points, it is necessary to consider the structural characteristics of the scaffolding, its stress conditions, and the load-bearing capacity of the building or other structures. A reasonable layout and connection method should be used to ensure that the newly added anchor points function effectively.

[0032] Cantilevered steel beams are one of the key load-bearing components in scaffolding. By optimizing the cross-sectional dimensions of cantilevered steel beams, they can achieve better stiffness and stability while still meeting load-bearing requirements. This helps reduce deformation and vibration of the scaffolding during stress, thus improving its overall performance.

[0033] When optimizing the cross-sectional dimensions of cantilever steel beams, factors such as their stress state, material properties, and manufacturing process need to be considered. Through reasonable calculations and simulations, the optimal cross-sectional dimensions and shape can be determined to ensure that the cantilever steel beams can effectively bear and transfer loads.

[0034] A detailed optimization design scheme needs to be developed based on the specific conditions and stress requirements of the scaffolding, and its effectiveness needs to be verified through calculation and simulation.

[0035] A system for analyzing the stress characteristics and deformation of a flower basket scaffold, comprising: Model building module: Used to build a three-dimensional finite element model of the flower basket scaffolding; Load application module: used to apply loads and boundary conditions; Calculation and analysis module: used to calculate the stress distribution and deformation of each component; Results optimization module: Used to optimize the scaffolding structure design based on the calculation results; Data storage module: Used to store data.

[0036] The module constructs a three-dimensional finite element model of the flower basket scaffolding. This module includes the following components: a cantilever steel beam modeling unit, which generates a finite element model of the cantilever steel beam based on the input dimensions, material properties, and support conditions of the cantilever steel beam, accurately simulating the structural characteristics of the cantilever steel beam and providing a basis for subsequent analysis.

[0037] The tie rod modeling unit generates a finite element model of the tie rod based on its length, cross-sectional area, material properties, and connection location, simulating the mechanical behavior of the tie rod and providing support for stress analysis.

[0038] The turnbuckle modeling unit generates a finite element model of the turnbuckle based on its geometric dimensions, material properties, and connection method, simulating the turnbuckle's adjustment function and mechanical behavior.

[0039] The anchor point modeling unit generates a finite element model of the anchor point based on its location and constraints (such as fixed end or hinged end), simulating the constraint effect of the anchor point and ensuring the accuracy of the model's boundary conditions.

[0040] The calculation and analysis module is used to perform stress and deformation analysis on the established finite element model. This module includes: a stress calculation unit, which calculates the stress distribution of each component based on the finite element model and the applied load, identifies stress concentration areas, and provides a basis for structural optimization; and a deformation calculation unit, which performs deformation analysis calculations based on the finite element model.

[0041] The result optimization module includes a structural optimization unit and a parameter adjustment unit. The structural optimization unit adjusts the structural parameters of the scaffolding based on the stress and deformation analysis results, such as the angle of the diagonal braces, the cross-sectional dimensions of the cantilever steel beams, and the number of anchor points, to improve the load-bearing performance and stability of the scaffolding and reduce construction risks. The parameter adjustment unit adjusts the parameters of each component according to the optimization plan, such as the cross-sectional area of ​​the diagonal braces and the adjustment length of the turnbuckles, to ensure the feasibility of the optimization plan and improve construction efficiency.

[0042] The data storage module includes the following components: a model data storage unit, which allows users to view and modify the model at any time; a calculation result storage unit, which stores and retrieves calculation results to provide a reference for subsequent analysis and optimization; an optimization scheme storage unit, which stores and retrieves optimization schemes to facilitate users in comparing and selecting the optimal scheme; and the data storage module receives data from the model building module, the calculation and analysis module, and the result optimization module.

[0043] Compared with the prior art, the beneficial effects of the present invention are: 1. Based on the results of finite element analysis, this invention can identify stress concentration areas and areas of excessive deformation, thereby guiding the structural optimization design of scaffolding. By adjusting the angle of the diagonal tie rods, increasing the number of anchor points, and optimizing the cross-sectional dimensions of the cantilevered steel beams, the load-bearing capacity and stability of the scaffolding can be effectively improved, and safety risks during construction can be reduced.

[0044] 2. By establishing a precise three-dimensional finite element model and combining it with the loads and boundary conditions of actual working conditions, this invention can accurately simulate the stress state of the basket scaffolding during actual construction, thereby calculating the stress distribution and deformation of each component. This precise analysis method greatly improves the accuracy and reliability of stress characteristics and deformation analysis. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1: Application of the present invention in high-rise building construction: In the construction of a high-rise building, basket scaffolding was used as the external scaffolding. The specific implementation steps are as follows: Step 1: Establish a 3D finite element model. Based on the building structure and construction requirements, establish a 3D finite element model including cantilevered steel beams, tie rods, turnbuckles, and anchor points. Input parameters include: The cantilevered steel beam has a length L = 5 meters, a cross-sectional dimension b × h = 200 × 400 mm², a material elastic modulus E = 200 GPa, and a moment of inertia I = 1.33 × 10⁷ mm. 4 The length of the diagonal tie rod is L=3 meters, the cross-sectional area is A=1000mm², and the elastic modulus of the material is E=200GPa; the diameter of the turnbuckle is d=20mm, and the elastic modulus of the material is E=200GPa; the anchorage point constraint type is fixed end.

[0049] Step 2: Apply loads and boundary conditions. Vertical load: Weight of construction personnel and materials, applied as a uniformly distributed load of q = 2 kN / m². Horizontal load: Wind load applied as Fw = 0.5 kN / m². Temperature change: Consider a temperature difference ΔT = 20°C, and the material's coefficient of thermal expansion α = 1.2 × 10⁻⁵ / °C. Boundary conditions: One end of the cantilevered steel beam is fixed, and both ends of the diagonal tie rod are hinged.

[0050] Step 3: Calculate stress and deformation using finite element analysis software (such as ABAQUS). The results are as follows: Maximum stress of the cantilever steel beam σ = 180 MPa. Maximum deformation of the tie rod ΔL = 2.5 mm.

[0051] Step 4: Optimize Structural Design: Based on the calculation results, adjust the angle of the diagonal braces to 75°, increase the number of anchor points, and optimize the cross-sectional dimensions of the cantilever steel beams. After optimization, the maximum stress of the cantilever steel beams is reduced to 150MPa, and the maximum deformation of the diagonal braces is reduced to 2mm, significantly improving the stability and safety of the scaffolding.

[0052] First, a stress characteristic and deformation analysis system for a basket scaffold is developed. In the model building module, a three-dimensional finite element model is created using professional finite element modeling software (such as ANSYS) based on the actual dimensions and material properties of the basket scaffold. This model includes key components such as cantilevered steel beams, tie rods, turnbuckles, and anchorage points. During the modeling process, the structural characteristics and connection methods of each component need to be accurately simulated to ensure the accuracy of subsequent analysis. In this example, based on the actual dimensions and material properties of the basket scaffold, detailed parameters of the cantilevered steel beams, tie rods, turnbuckles, and anchorage points are recorded. Specifically, the length of the cantilevered steel beam is L = 5 meters, the cross-sectional dimensions are b × h = 200 × 400 mm², the material elastic modulus is E = 200 GPa, and the moment of inertia is I = 1.33 × 10⁷ mm². 4 The tie rod has a length L = 3 meters, a cross-sectional area A = 1000 mm², and a material elastic modulus E of 200 GPa. The turnbuckle has a diameter of 20 mm and a material elastic modulus E = 200 GPa. Anchor points are set as fixed-end constraints. A three-dimensional finite element model containing all the above key components was constructed using professional finite element modeling software (such as ANSYS). Special attention was paid to the structural characteristics and connection methods of each component during modeling to ensure the accuracy and reliability of the model.

[0053] Then, in the load application module, loads and boundary conditions are applied according to the actual working conditions. Loads include vertical loads (such as the weight of the scaffold itself, material weight, etc.), horizontal loads (such as horizontal thrust during construction, wind load, etc.), and wind loads. Boundary conditions include fixed-end constraints and hinged-end constraints, used to limit the displacement and rotation of the scaffold. These loads and boundary conditions need to be specifically set and adjusted according to the actual situation. Based on the actual situation during construction, vertical and horizontal loads were applied. Vertical loads mainly include the weight of the scaffold itself, the weight of construction personnel and materials, etc., applied as a uniformly distributed load of q = 2 kN / m². Horizontal loads include horizontal thrust and wind loads during construction, with wind load applied at F_w = 0.5 kN / m². Considering the thermal expansion effect of materials due to temperature changes, a temperature difference ΔT = 20°C and a material thermal expansion coefficient α = 1.2 × 10^-5 / °C were also input. Based on the actual constraints of the scaffolding, boundary conditions were set such that one end of the cantilever steel beam was fixed and both ends of the diagonal tie rod were hinged.

[0054] Next, in the calculation and analysis module, the established model is solved using finite element analysis software. The calculations yield results such as stress distribution diagrams and deformation diagrams for each component. These results visually demonstrate the stress distribution and deformation of the scaffolding during the stress process, providing a basis for subsequent optimization design.

[0055] Finally, in the results optimization module, the scaffolding design was optimized based on the analysis results of stress distribution and deformation. Measures such as adjusting the angle of the diagonal braces, increasing the number of anchor points, and optimizing the cross-sectional dimensions of the cantilevered steel beams were used to improve the load-bearing capacity and stability of the scaffolding. Simultaneously, specific optimization schemes needed to be developed considering factors such as the actual conditions of the construction site and construction efficiency, and their effectiveness was verified through calculation and simulation. Based on the results obtained from the calculation and analysis module, the scaffolding design was optimized as follows: Adjusting the angle of the diagonal braces: The angle of the diagonal braces was adjusted to 75° to improve their stress performance. Increasing the number of anchor points: By increasing the number of anchor points, we improved the overall stability of the scaffolding. Optimizing the cross-sectional dimensions of the cantilever steel beams: The cross-sectional dimensions of the cantilever steel beams were optimized to reduce their stress levels. After optimization, the maximum stress of the cantilever steel beams was reduced to 150MPa, and the maximum deformation of the diagonal braces was reduced to 2mm, significantly improving the stability and safety of the scaffolding.

[0056] Finally, a data storage module can be set up to store and manage model data, calculation results, and optimization schemes. This allows users to easily view and modify the model, retrieve and analyze calculation results, and compare and select the optimal solution. With the support of the data storage module, analysis efficiency and optimization effectiveness can be further improved.

[0057] Example 2: Application of the present invention in the construction of complex facade buildings: In the construction of a building with a complex facade, the scaffolding needs to adapt to different facade shapes. The specific implementation steps are as follows: Step 1: Establish a three-dimensional finite element model Based on the building facade shape, a three-dimensional finite element model including cantilevered steel beams, tie rods, and turnbuckles was created. The input parameters are the same as in Example 1, but the facade shape is more complex, requiring adjustment of the anchor point positions.

[0058] Step 2: Apply loads and boundary conditions. Vertical load: Apply a uniformly distributed load of q = 2 kN / m².

[0059] Horizontal load: Wind load is applied at Fw = 0.5 kN / m²; Temperature change: Temperature difference ΔT = 20°C; Boundary conditions: One end of the cantilever steel beam is fixed, and both ends of the diagonal tie rod are hinged.

[0060] Step 3: Calculate stress and deformation. The calculation results show that the maximum stress of the tie rod is σ = 220 MPa. The maximum deformation of the cantilever steel beam is ΔL = 3.2 mm.

[0061] Step 4: Optimize the structural design. Based on the calculation results, adjust the cross-sectional dimensions of the cantilever steel beams, increase the number of diagonal tie rods, and optimize the anchorage layout. After optimization, the maximum stress of the diagonal tie rods is reduced to 180MPa, and the maximum deformation of the cantilever steel beams is reduced to 2.8mm, ensuring the safety and stability of the scaffolding in complex environments.

[0062] First, in the model building module, a stress characteristic and deformation analysis system for a basket scaffold is used to create a three-dimensional finite element model based on the actual dimensions and material properties of the basket scaffold. This model includes key components such as cantilevered steel beams, tie rods, turnbuckles, and anchor points. During the modeling process, it is necessary to accurately simulate the structural characteristics and connection methods of each component to ensure the accuracy of subsequent analysis. In this example, based on the actual dimensions and material properties of the basket scaffold, the parameters of the cantilevered steel beams, tie rods, turnbuckles, and anchor points are recorded in detail. Specifically, the length of the cantilevered steel beam is L = 5 meters, the cross-sectional dimensions are b × h = 200 × 400 mm², the elastic modulus of the material is E = 200 GPa, and the moment of inertia is I = 1.33 × 10⁷ mm². 4 The tie rod has a length L = 3 meters, a cross-sectional area A = 1000 mm², and a material elastic modulus E of 200 GPa. The turnbuckle has a diameter of 20 mm and a material elastic modulus E = 200 GPa. Anchor points are set as fixed-end constraints. A three-dimensional finite element model containing all the above key components was constructed using professional finite element modeling software (such as ANSYS). Special attention was paid to the structural characteristics and connection methods of each component during modeling to ensure the accuracy and reliability of the model.

[0063] Then, in the load application module, loads and boundary conditions are applied according to the actual working conditions. Loads include vertical loads (such as the weight of the scaffold itself, material weight, etc.), horizontal loads (such as horizontal thrust during construction, wind load, etc.), and wind loads. Boundary conditions include fixed-end constraints and hinged-end constraints, used to limit the displacement and rotation of the scaffold. These loads and boundary conditions need to be specifically set and adjusted according to the actual situation. Based on the actual situation during construction, vertical and horizontal loads were applied. Vertical loads mainly include the weight of the scaffold itself, the weight of construction personnel and materials, etc., applied as a uniformly distributed load of q = 2 kN / m². Horizontal loads include horizontal thrust and wind loads during construction, with wind load applied at F_w = 0.5 kN / m². Considering the thermal expansion effect of materials due to temperature changes, a temperature difference ΔT = 20°C and a material thermal expansion coefficient α = 1.2 × 10^-5 / °C were also input. Based on the actual constraints of the scaffolding, boundary conditions were set such that one end of the cantilever steel beam was fixed and both ends of the diagonal tie rod were hinged.

[0064] Next, in the calculation and analysis module, the established model is solved using finite element analysis software. The calculations yield results such as stress distribution diagrams and deformation diagrams for each component. These results visually demonstrate the stress distribution and deformation of the scaffolding during the stress process, providing a basis for subsequent optimization design.

[0065] Finally, in the results optimization module, the scaffolding design was optimized based on the analysis results of stress distribution and deformation. Measures such as adjusting the angle of the diagonal braces, increasing the number of anchor points, and optimizing the cross-sectional dimensions of the cantilevered steel beams were used to improve the load-bearing capacity and stability of the scaffolding. Simultaneously, specific optimization schemes needed to be developed considering factors such as the actual conditions of the construction site and construction efficiency, and their effectiveness was verified through calculation and simulation. Based on the results obtained from the calculation and analysis module, the scaffolding design was optimized as follows: The structural design was optimized by adjusting the cross-sectional dimensions of the cantilever steel beams based on calculation results, increasing the number of diagonal tie rods, and optimizing the anchorage layout. After optimization, the maximum stress of the diagonal tie rods was reduced to 180 MPa, and the maximum deformation of the cantilever steel beams was reduced to 2.8 mm, ensuring the safety and stability of the scaffolding in complex environments.

[0066] Finally, a data storage module can be set up to store and manage model data, calculation results, and optimization schemes. This allows users to easily view and modify the model, retrieve and analyze calculation results, and compare and select the optimal solution. With the support of the data storage module, analysis efficiency and optimization effectiveness can be further improved.

[0067] The working principle of this invention is as follows: A method for analyzing the stress characteristics and deformation of a flower basket scaffolding, through the coordinated work of the following modules, achieves accurate stress analysis and deformation assessment of the flower basket scaffolding, and provides an optimized design scheme.

[0068] Furthermore, we can further refine the implementation cases in practice.

[0069] Based on the above, an intelligent analysis platform will be developed. This platform will automatically receive user-input parameters for the basket-shaped scaffolding (such as dimensions, materials, and connection methods) and automatically generate a 3D finite element model based on these parameters. Simultaneously, the platform can integrate advanced AI algorithms, such as machine learning or deep learning models, to predict and optimize the stress performance and stability of the scaffolding. (A smart optimization algorithm will be developed, combining machine learning or deep learning algorithms, to automatically optimize the structural design of the scaffolding. This algorithm can automatically adjust the structural parameters of the scaffolding, such as the angle of the tie rods and the cross-sectional dimensions of the cantilever steel beams, based on real-time collected data and preset optimization objectives, to achieve optimal stress performance and stability. First, a large amount of stress characteristics and deformation data of the scaffolding will be collected as a training dataset. Then, machine learning or deep learning algorithms will be used to train the training data to obtain the smart optimization model. In practical applications, the real-time collected data will be input into the smart optimization model, and the model will automatically output the optimized structural parameters.)

[0070] Real-time feedback and adjustment: During the analysis process, the platform can monitor and provide feedback on the stress distribution and deformation of the model in real time, and automatically adjust the structural parameters of the scaffolding, such as the angle of the tie rod and the cross-sectional dimensions of the cantilever steel beam, based on the analysis results to achieve the optimal stress state.

[0071] These are also very easy to implement. First, strain gauges, displacement sensors, and stress sensors are installed on the key parts, nodes, and members of the flower basket scaffolding. Among them, strain gauges are used to measure the strain data of the members; displacement sensors are used to measure the displacement data of the members; and stress sensors are used to measure the stress data of the members. Environmental parameters at the construction site, including temperature, humidity, and wind speed, are collected using temperature, humidity, and wind speed sensors. The actual load data is monitored by weighing sensors installed on the scaffolding; Record construction operation information during the construction process; Based on the strain data, displacement data, stress data, environmental parameters, actual load data, and construction operation information of the members, the original data of the basket scaffolding under actual working conditions are determined.

[0072] 1. Multi-condition analysis and optimization: Dynamic load simulation: In addition to considering static loads, the platform should also be able to simulate dynamic loads, such as wind loads and seismic loads, to evaluate the stress performance and stability of the scaffolding under different working conditions.

[0073] Multi-objective optimization: Based on the results of multi-condition analysis, the platform can execute multi-objective optimization algorithms, taking into account multiple performance indicators (such as stress, deformation, stability, etc.) to find the optimal scaffolding design scheme.

[0074] For example, in some embodiments, task analysis is performed on the flower basket scaffolding under actual working conditions, specifically including: The stress, strain, and displacement distributions of the basket scaffolding under static loads were calculated by solving the finite element equilibrium equations. The natural frequencies and mode shapes of the basket scaffolding are calculated by solving the eigenvalue problem formula. The response of the scaffolding under dynamic loads is solved using time history analysis and step-by-step integration.

[0075] Furthermore, during the design process, we discovered that we could utilize virtual reality (VR) and augmented reality (AR) technologies, allowing users to intuitively view and analyze the stress state and deformation of the scaffolding. This helps construction workers better understand the structural characteristics of the scaffolding and allows for thorough verification and testing before construction.

[0076] On the other hand, based on the virtual simulation results, further physical verification experiments can be designed and conducted to verify the accuracy and reliability of the analysis results. This helps to further enhance the credibility of the method in practical applications.

[0077] The analysis platform is designed with a modular structure, with each module responsible for a specific function (such as model building, load application, and calculation analysis). This design makes the platform easy to maintain and upgrade, and can be expanded according to user needs.

[0078] The platform should support integration with other software or systems, such as BIM (Building Information Modeling) systems and construction management software. This facilitates seamless data sharing and collaborative work, improving construction efficiency and quality.

[0079] At the construction site, sensors can be deployed to monitor the stress and deformation of the scaffolding in real time. Based on this monitoring data, the platform can automatically adjust the structural parameters of the scaffolding to adapt to changes during the actual construction process.

[0080] When the platform detects that the stress or deformation of the scaffolding exceeds the preset range (by setting reasonable risk thresholds, such as stress limit value, deformation limit value, etc.), it can automatically issue an early warning signal to remind construction personnel to take necessary measures to ensure construction safety.

[0081] For example, the actual method we use in practice for safety warning of flower basket scaffolding is as follows: Based on safety standards and specifications, different types of early warning thresholds are set, including stress early warning values, strain early warning values, and displacement early warning values; the stress results, strain results, and displacement results obtained from finite element analysis are compared with the corresponding early warning thresholds respectively; The stress result YL obtained from the finite element analysis is compared with the material stress warning value YLZ. If YL > YLZ, it is determined that the stress of the member exceeds the allowable value and there is a safety hazard, and a warning signal is immediately triggered; otherwise, it is determined that the stress of the member meets the safety standard. The strain result YB is compared with the specified displacement warning value YBZ. If YB > YBZ, it means that the strain on the scaffold exceeds the specified range and there is a safety hazard, and the warning signal is triggered immediately; otherwise, it means that the strain on the scaffold still meets the safety standards. The displacement result WY is compared with the specified displacement warning value WYZ. If WY > WYZ, it indicates that the scaffold deformation exceeds the specified range and there is a safety hazard, and a warning signal is triggered immediately; otherwise, it indicates that the scaffold deformation still meets the safety standards.

[0082] Further investigation in our implementation case revealed the potential to integrate machine learning algorithms, such as deep learning or reinforcement learning, into the results optimization module for automated analysis and optimization of scaffolding structures. These algorithms can learn from historical data and simulation results to predict the impact of different design parameters on the stress performance and stability of the scaffolding, thereby automatically proposing the optimal design solution. Furthermore, multi-objective optimization techniques are introduced, simultaneously considering multiple objectives such as the stress performance, stability, material cost, and construction efficiency of the scaffolding. The algorithm automatically weighs these objectives to find the optimal design solution that meets all requirements. This multi-objective optimization model is essentially a combination of the above embodiments, requiring only comprehensive calculations without additional design. Our design incorporates the ability of the optimization module to automatically adjust the scaffolding design parameters based on changes in actual conditions at the construction site (such as wind speed and load variations), ensuring its safety and stability throughout the construction process.

[0083] For example, in some practical analyses, we can perform feature extraction on the data; specifically including but not limited to: Calculate the maximum, minimum, mean, median, and variance of the strain data to determine the characteristics of the strain data; Calculate the maximum, minimum, mean, median, and variance of the stress data to determine the characteristics of the stress data; Calculate the rate of change of displacement data measured by the displacement sensor to obtain the displacement data characteristics; Based on the characteristics of strain data, stress data, and displacement data obtained through calculation.
