The Research Of BIM Technology In Structural Design Stage Of Building Engineering

As a revolutionary technology to realize the informationization of the construction industry,BIM technology has been vigorously developed in China in recent years.The whole life cycle of a construction project includes the planning stage,design stage,construction stage,operation and maintenance stage,and many participating units.Under the traditional working mode,the various stages of the construction engineering life cycle and the participating units are relatively independent,and the created data are separated from each other,resulting in low information transmission efficiency and inconsistent information.The use of BIM technology in the whole life cycle of the building can realize the transmission and sharing of information at all stages,solve the problem of information splitting at each stage,and make the construction project significantly improve the quality and efficiency throughout the process,and greatly reduce the possible risks.As the upstream stage of the construction engineering life cycle,the application level of BIM technology determines the success of BIM technology in the whole life cycle of construction engineering.The ideal state of the BIM application in the design phase is that the designer directly uses the BIM software for the full-scale collaborative design,and then generates the two-dimensional and three-dimensional results based on the BIM model,the so-called "forward design" mode.However,due to the need to separately establish structural calculation models,construction drawings to draw flat,and mainly express information as rebar information,the BIM application level in the design stage has lagged behind other professions,and the structural profession has become the design stage.Professional BIM is a short board for positive design.Therefore,studying the application of BIM technology in the structural design stage of construction engineering has certain value and practical significance for realizing the full-professional BIM “ forward design” in the design stage and promoting the BIM application of the whole life cycle of the building.In order to realize the BIM application in the whole process of the structural design stage,this paper focuses on the design process of BIM structure design and the BIM application points in the process.The main research contents are as follows:1.Analyze and comb the traditional structure design process,summarize the problems and defects in the traditional structure design process,combine the BIM technology with the traditional structure design process,and propose the BIM structure design process based on BIM technology.To achieve the full process BIM application in the structural design phase.2.Extract the BIM application points such as BIM modeling,collision detection,model mutual guidance,collaborative design,and flat construction drawing drawing involved in the BIM structural design flow,and study the specific implementation of each application point under current technical conditions.The method and the application value analysis of each BIM application point ensure that the BIM structure design process can be fully realized and maximized value.3.Carry out systematic research on the secondary development technology of Revit software and the secondary development technology of ABAQUS software,and investigate the development status and development methods of the current model conversion interface,and demonstrate the Revit model and ABAQUS through the software secondary development method.The feasibility of converting interface development between models.4.Based on the secondary development of Revit software and the secondary development technology of ABAQUS software,the conversion interface program of Revit model and ABAQUS model is programmed to realize the function of converting Revit model into ABAQUS finite element analysis model,and the program correctness is implemented for the conversion interface and verification with versatility.
