Abstract: Based on building Information Model(BIM, Building Information Model), this paper introduced a method of adding related parameters such as material attribute and constitutive relation of concrete by the study of the standard file format of IFC(Industry Foundation Class).The"Data Integration Module"written by C++ could access and analyze the necessary data of IFC files, and then it generated the input file of section nonlinear analysis program. Finally, after comparing with the experiment results, the computational result of steel fiber reinforced concrete beam by the nonlinear program fits well.
