| Abstract: |
Currently, the seismic performance assessments of long span bridges are generally conducted using commercial finite element (FE) software packages, which to some extent limit the in-depth investigation of associated topics. A numerical model system is proposed to simulate a super long span cable-stayed bridge with a maximum span of 1500 m based on an open source FE software package (i.e., OpenSees). The seismic performance of this bridge is investigated. The simulation results of OpenSees and the commercial software MSC.Marc are compared with a good agreement. Furthermore, a collapse simulation of the bridge is also successfully performed and the corresponding collapse mechanism is revealed. The research outcome could provide a reference for further studies on the seismic performance of super long span cable-stayed bridges based on open source FE programs. |
