Abstract	IFC is key enabler for data interoperability of BIM models. This enables reusing the geometry for structural analysis, thus saving modeling time. BIM models and the IFC format consists of solid elements, therefor the imported geometry will generate solid elements when meshed. When performing structural analysis with the finite element method on concrete structures the use of shell and beam elements is preferred. A method has been developed to import BIM models into BRIGADE/Plus generating shell and beam elements when useful. The method works quite well importing most elements in an efficient way, given that definitions in the BIM model are sufficient. The result is that the user will have to spend less time rebuilding the geometry. Often the design engineer has not given parts definitions suitable for the structural analysis. The import will then not suffice and the geometry in the structural analysis has to be reconstructed. When importing a BIM model for structural analysis, a feature that would be beneficial is the opportunity to choose simplification for geometrical objects.
