In this paper,the space beam gird model for a long-span rigi d-framed flexible CFST arch bridge in YiWan railway is established.Considering geometric and material nonlinear,the ultimate load capacity of CFST arch bridge at usage is analyzed.The results show that space beam gird model is a More reasonable method,which imitate initial disfigurement of structure better.
