Research On The Structural Analysis Model With Eccentric Members Based On Industry Foundation Classes Standard

The traditional building design method could not satisfy various kinds of information and data sharing among sorts of systems during treatment of massive and fine building project in the past.As a data base,IFC standard can achieve muti-professional and multilevel integration management and offer data sharing and transmission.Today,with the increasing complexity of building projects,the target of realizing cross professional cooperation is increasingly urgent.The current structural analysis of model data transformation is mainly focus on point-to-point single direction data transformation model.The accuracy and extendibility of the tranformation mechanism have much room for improvement.And what's more,data transforamtion of component eccentricity is lack of reseach and systematic solution.Because the different expressions of structure eccentric data from various professional softwares during the transformation process of structural analysis model,the structure eccentric data always has deviation,loss or distortion during the transforamtion process.Considering that the data transformation based on IFC standard can satisfy the sharing and exchange of structural models among different professional software,and the transformation of eccentric data into IFC files still need systematic optimization and solution in the practical application,this article makes further research on the transformation of eccentric data from SGF digital format file to IFC data standard,expands the primary algorithm of general structure model transformation,and realizes the transformation of eccentric data from SGF general structure analysis model to IFC structure model.In the implementation of specificcase,it uses Squlite and Visual C++ and other development tools to transform the structure analysis model from YJK building software to IFC structure model,which improved the original SGF and SGFtolFC model,effectively completed the extraction and processing of structure eccentric information,set up a sharing interface between YJK building software and IFC data standard,and had reduced the required work of remodeling to some degree.
