To the problem of BIM model can not be directly applied to the finite element structural analysis calculation,this paper carries out the research of extracting BIM model data and transforming it into finite element calculation model data.By formulating the modeling rules for BIM model of high-piled wharf and developing data interface software based on the specific structural calculation software,the extracted data from the BIM model is converted into the calculation data for the structural calculation software.The finite element structure calculation model is created through the calculation software for internal force calculation,achieving data transfer from BIM model to finite element calculation model.Engineering practice shows that this technology can transmit data accurately and improve design efficiency.
