| Building information modeling(BIM)is a newly developed information technology in the construction industry.This technology is leading the construction industry from two-dimensional model to three-dimensional model,and realizing the information sharing process of the whole life cycle of construction,which will bring revolutionary changes to the construction industry.Multi-ribbed composite panel structure has been widely concerned in the field of construction engineering because of its advantages of light weight,environmental protection,excellent structural performance and high assembly efficiency.However,the mechanical calculation and analysis of structural model has always independed of the application of BIM Technology;At the same time,the realization of "mechanical calculation" process of multi-ribbed composite panel structure system also needs to be further studied.Based on the above two specific problems,this paper studied the data transform of multiribbed composite panel structure model based on BIM technology.The specific work contents and results are as follows:(1)By analyzing the data content and definition level of BIM model of multiribbed composite panel structure,the data requirements of model transformation were determined.Combined with the structural characteristics of multi-ribbed composite panel and the modeling characteristics of structural analysis model,an external database which suitable for model data transformation was designed.(2)Combined with the content of database design,a complete set of data processing interface was developed.The software interface provides a series of methods such as data standardization inspection,data classification and component relationship processing,which can realize the complete process of data processing and transformation.(3)Based on Windows system,.Net framework and visual studio 2019,which adopted C# programming language and Revit API to complete the secondary development of Revit,and realized the classification and extraction function of model data;The structural calculation software SAP2000 was completed the work of secondary development through CSi API,and the automatic modeling function of multiribbed composite panel structure in SAP2000 was realized.(4)Combined with the research contents of(2)and(3),the software Revit To SAP2000 was developed.The software realizes two specific functions: one is the export of Revit structural model data to the external database,and the other is the model generation of SAP2000. |
