Description

Technical Field

[0001] This invention belongs to the field of building structure design technology, and in particular relates to a forward structural design method based on the PKPM BIMBase platform. Background Technology

[0002] Traditional building structural design methods mostly employ two-dimensional design, which suffers from long design cycles, poor information exchange, and high error rates. With the digital transformation of the construction industry, BIM (Building Information Modeling) technology has become an important means to improve design efficiency, ensure project quality, and reduce construction costs, and three-dimensional forward design methods are gradually becoming mainstream. PKPMBIMBase, as the first domestically developed and controllable BIM platform, features parametric modeling, data interaction, and collaborative design functions, providing strong support for the three-dimensional forward design of building structures. However, currently, the market lacks a systematic and efficient structural forward design method based on the PKPMBIMBase platform. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a structural forward design method based on the PKPM BIMBase platform, which can automate the entire process from preliminary design to construction drawing generation, improve design efficiency and quality, and ensure the security and controllability of design data, thereby achieving efficient and accurate design of building structures.

[0004] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0005] A structural forward design method based on the PKPM BIMBase platform includes the following process: Step 1: Preliminary design of BIM structural model; Step 2: Structural calculation and analysis; Step 3: Based on the analysis results of Step 2, refine the model design; Step 4: Output construction drawing files; Step 5: Data management, data sharing and collaboration, and data backup.

[0006] Furthermore, step 1 specifically includes: Using the parametric modeling capabilities of the PKPM BIMBase platform, a building model is created. Based on the architectural design requirements, a preliminary BIM structural model is quickly built, including steps such as selecting component types (including beams, columns, floor slabs, and walls), setting component parameters (including dimensions, materials, and connection methods), and adjusting component positions. Then, the preliminary BIM structural model is reviewed to ensure that the model meets the basic design requirements.

[0007] Furthermore, step 2 specifically includes: Import the preliminary BIM structural model into the PKPM preprocessing built-in structural analysis module, set the analysis parameters, including load type, boundary conditions, and analysis cases, and then perform load analysis, internal force analysis, and deformation analysis to obtain analysis results, including key indicators related to displacement, stress, and strain; design optimization suggestions are automatically fed back based on the analysis results.

[0008] Furthermore, step 3 specifically includes: Based on the structural calculation and analysis results in step 2, the BIM structural model is further refined and adjusted, including refining component dimensions, adding node connections, and adjusting component layout. By merging the models of various disciplines such as building structure, water supply, heating and electricity, and using the platform's collision detection function to perform collision checks on the BIM structural model, the collision problems in the model can be identified and resolved. By utilizing the platform's headroom analysis function, headroom analysis is performed on the BIM structural model to ensure that the model meets the building's functional and aesthetic requirements.

[0009] Furthermore, step 4 specifically includes: Based on the model refinement, the construction drawing generation function of the PKPM BIMBase platform is used to review and verify the construction drawings, generating structural construction drawings that meet the specifications. The output construction drawing files include beam reinforcement drawings, column reinforcement drawings, and slab reinforcement drawings.

[0010] Furthermore, step 5 specifically includes: By utilizing the data management functions of the PKPM BIMBase platform, all data in the design process is managed and stored in a unified manner, including model data, analysis data, and construction drawing data. At the same time, through the platform's collaborative design functions, data sharing and collaboration among design teams are realized, including sharing, viewing, and modifying models, ensuring consistency of progress, and providing timely feedback on issues. Additionally, data backup and recovery operations are performed during the design process.

[0011] The present invention has the following beneficial effects: 1. Improve design efficiency: By integrating parametric modeling and structural calculation and analysis, the system enables rapid construction and real-time analysis of structural models, significantly shortening the design cycle and improving design efficiency.

[0012] 2. Ensure design quality: Utilize the collision detection and headroom analysis functions of the PKPM BIMBase platform to automatically optimize and adjust the structural model, reduce manual intervention, ensure the accuracy and feasibility of the design, and effectively avoid errors and omissions.

[0013] 3. Promote collaborative design: Through the data interaction and collaborative design functions of the PKPM BIMBase platform, data sharing and collaboration among design teams can be achieved, thereby improving overall design efficiency and quality.

[0014] 4. Ensure data security: Based on the independently controllable PKPM BIMBase platform, the building structure design is made independently controllable, ensuring the security and controllability of design data and avoiding data leakage and loss. Attached Figure Description
