The Application Of BIM Technology In The Collaborative Design And Structural Opti-Mization Of A Library

Building Information Modeling(BIM)converts all engineering data and physical features into three-dimensional information parameters and establishes 3D models.These building information data can be processed,modified,recalled,shared,and exported throughout the entire life of a building,helping engineers improve deci-sion-making quality and efficiency,save engineering project costs,and reduce engi-neering risks.In recent years,China’s BIM technology has developed rapidly.The above advantages of BIM have been utilized in the construction of building design,construction,operation and maintenance.However,the application of BIM technology in the structural design stage is still based on the traditional design of the post-mold mode.This approach not only increases the design process and design costs,but also fails to reflect the application value of BIM in the structural design stage.At the same time,traditional structural optimization tends to focus on structural reliability,and it is difficult to take into account the synergy between the optimization objectives and the entire professional and construction phase and cost control.With the increase in the scale of construction projects and the complexity of building structures,the traditional structural optimization design method And the process needs to be improved.There-fore,from the point of view of structural design,the application of BIM in project structure design and structural optimization is of great practical significance and ref-erence value for the function of BIM technology in the design stage.This article introduces the project examples of BIM technology applied at home and abroad,and summarizes the application points and workflow of BIM in traditional design methods.Aiming at the traditional architectural structure design and structural optimization,taking a university library project as an engineering example,BIM technology is applied to the architectural,structural collaborative design and structural optimization design of the project,discussing the BIM technology collaborative de-sign method and process,and BIM.Technology applied to the feasibility of structural optimization design.Firstly,through the PBIMS system,a professional 3D infor-mation model for engineering examples was established,and the BIM collaborative design method and basic flow were summarized.Then,the BIM technology was ap-plied to the engineering examples through the bi-directional link between the PBIMS system and the GLI.The overall optimization of the structural optimization scheme was selected,the traditional structural optimization scheme was converted into a 3D model,and the engineering quantities output from the BIM design were counted.The project quantities list of different schemes was obtained,and the amount of concrete and reinforcement used to affect the project cost were comprehensively considered.The amount of template and the amount of artificial consumption and other factors were used to calculate the project cost data of different optimization schemes.Differ-ent structural schemes were selected.Finally,combining the optimization results,the method of applying BIM technology was compared with the traditional design method.The differences between the two in terms of work collaboration methods,information management levels,and value of design results are summarized.The advantages of BIM collaborative design and the basic methods of BIM applied to optimal design are summarized.The research in this paper is helpful to realize the effective control of project cost in the stage of design and optimization of structural design,and provide certain reference and basis for the practical application of BIM technology in struc-tural design.
