| Abstract: | The finite element model for a long-span abnormal-shaped pedestrian bridge with steel box girder located over Qinhuai River in Nanjing city is presented in this paper.The baseline finite element model for the bridge is then proposed and the corresponding static and dynamic analysis is performed on the basis of ANSYS combined with secondary development function.The design parameter optimization process is also carried out to draw some useful conclusions,which can be taken as reference for the structural design of bridge with similar configuration as well as the solution to software development in ANSYS for similar research. |
