Research On Interface Development Of BIM Model Transformation And Structural Mechanics Analysis

As a physical attribute and functional digital expression in the construction project,BIM begins with the conceptual design of the previous period and runs through the whole life cycle process of the entire construction project,and provides a platform for the parties to exchange information for the decision of all parties.And resource sharing.BIM technology is another revolutionary cross-professional technological advancement since the large-scale promotion of CAD.It aims to promote the integration process of informationization in the industry and promote the overall production efficiency of the construction industry.The structural design links of modern buildings often have a variety of engineering information,monitoring and attention to detail,complicatting construction procedures,wide-ranging and comprehensive,how to effectively classify and manage information and use resources to avoid Waste have become an urgent problem to be solved in structural design optimization and construction management.At the same time,with the increasing complexity of the building structure,the safety of its structure has also received more and more attention from people.How to perfectly simulate the real house structure and carry out effective structural analysis to ensure the accuracy of the calculation results of its building structure becomes modern The focus of the building structure design link.This paper summarizes the development and improvement of BIM technology at home and abroad,the functional characteristics of BIM,BIM technology coherent software and mainstream finite element software,and elaborates the functional characteristics and pre-development preparation process of Revit software and ANSYS software.The specific process of structural analysis in the finite element analysis software is combined with the BIM technology for functional programming.In this paper,the experimental model and the traditional method are used to verify and analyze.The interface program developed by Revit API interface is used to realize the information conversion between Revit and ANSYS software,including engineering information extraction,finite element mesh unit self-control division and finite element analysis function.The structural response module under gravity load,the structural response module under wind load,the structural modal analysis moduleand the structural response module under earthquake action are studied.The verification results of the analytical model designed in this paper show that the program developed in this paper has universality,meets the required functional requirements,and the program runs stably.The whole process automation does not require manual intervention.The guide menu and interface UI conform to the user's normal usage habits.And it can be applied to specific engineering practices.
