| Abstract: | Considering the non-linear features of the structure,the study adopts the large-scale finite element analyzing program ANSYS,to establish the two or three-dimensional finite element benchmark models of the single main beam and the three main beams,analyzes the component parameter,such as the section form of the main beam and the diaphragm,which influence the open section main beam,researches the influence law of its changes on the dynamic features of the stayed-cable bridges with open section main beam,and achieves some valuable conclusions. |
