Structure Information Transformation Based On BIM And Data Mapping

Recently, with the vigorous promotion by relevant government departments and urgent need of technical innovation of the traditional building civil engineering, BIM (Building Information Modeling) is increasingly applied in the whole project life cycle of building construction, especially in the engineering design stage. The application of BIM greatly deepen mutual communication between different professionals and the project participants at all stages so as to improve product quality and work efficiency of the traditional engineering industry. But at present the application of BIM in engineering design mainly stays in Architecture design and MEP design while the application in Structure design is still relatively behind. The cause of this situation mainly has two aspects:on the one hand, the core modeling software of the current mainstream BIM platforms mainly focus on solid model, whose model formats are not conducive to proceed Structure analysis; on the other hand, at present most structure analysis software, especially the traditional commercial Structure analysis software, have their own independent and closed ecosystem for model establishment and structure analysis.In order to promote the solution of these problems, it is recommended to improve BIM utility ratio in the field of structure design. This paper is to provide a reasonable and stable information transmission method, to realize the information interaction between Autodesk Revit software and the analysis platform independently developed by our team, and to provide a new idea in the Structure analysis with Revit applied. Specific content is as follows:(1)Based on the study on the development of BIM and BIM Related field such as the mainstream software platform, this part of paper mainly fixes on around the Autodesk BIM platform's core modeling software Revit structure information interaction. First build several representative structures model in Revit Structure module by elaborate modeling method; and then test the Revit API based secondary development; Implement extraction of structure information from the information model by CSiXRevit plug-in; thereafter, import the model data into the CSI structure analysis software platform; finally extract generated plain text structure information file.(2) To realize the transmission of structure information, research on the transformation of structure information between file formats, one of the generated plain text, the other of file required by the analysis platform independently developed by our team; put forward a kind of interface application framework based on intermediate data format; and by VC++ programming language define the intermediate data and achieve data mapping between two file formats. Finally through the generated plain text structure information file of several representative structures model extracted from Revit Structure module and the transmission of these structure information into the analysis platform by the proposed interface application, test and verify the stability and reliability of this structure information transmission approach and corresponding interface application.
