Abstract: Data standards are the basis for resolving information sharing and exchange issues. As the
international data standard for the data exchange in building information modeling, industrial
foundation classes (IFC), released by buildingSMART alliance, is designed to coordinate work of
different disciplines and software at different stages throughout the lifecycle of buildings. At present,
the information exchange between architectural and structural domains is the most urgent issue in the
process of multi-specialty cooperation in AEC/FM (architecture, engineering, construction & facility
management) industry. In the structural domain, the issue of eccentric members exerts a considerable
influence on the analysis of structural models. With regards to the data conversion of different
structural analysis software, this paper extracts the data representation of eccentric members, and
designs a conversion algorithm for eccentric structural model through a data conversion platform
based on the structural general format (SGF), which is used for data interoperability among various
commercial structural software. Moreover, C++ is employed in the research to achieve the
transformation for the eccentric members of structure models using IFC format.
