The numerous construction projects in China provide the best environment for the development of information technology applied in building design.Various commercial CAD/CAE software applications are purchased by design firms for multi-disciplinary design tasks.However,researches on integration and interoperability are seldom considered.This study pursues a breakthrough point of integration in the architectural and structural domains and expects further development in other aspects.A central building information modeling (BIM) framework based on the industry foundation classes (IFC) is proposed to handle the data exchange between IFC-compatible architectural models and structural models.A central XML(extensible markup language)-based unified finite element model (FEM) is proposed for model conversion among various commercial structural CAE software applications.In addition to bidirectional data interfaces among IFC-based BIM,XML-based FEM and various commercial FEMs,some other components such as visualization,calculation and model editing/check are also equipped into the prototype system.
The numerous construction projects in China provide the best environment for the development of information technology applied in building design.Various commercial CAD / CAE software applications are purchased by design firms for multi-disciplinary design tasks. Tips, researches on integration and interoperability are seldom considered .This study pursues a breakthrough point of integration in the architectural and structural domains and expects further development in other aspects. A central building information modeling (BIM) framework based on the industry foundation classes (IFC) is proposed to handle the data exchange between IFC -compatible architectural models and structural models. A central XML (extensible markup language) -based unified finite element model (FEM) is proposed for model conversion among various commercial structural CAE software applications. In addition to bidirectional data interfaces among IFC-based BIMs, XML-based FEM and various commercial FEMs, some other component s such as visualization, calculation and model editing / check are also equipped into the prototype system.
