Elastoplastic Analysis on Seismic Response of Long-Span Composite Beam Cable-Stayed Bridge

The seismic behavior of composite beam cable-stayed bridges, a competitive bridge type in long-span bridges, is increasingly valued in high-intensity seismic zones. In this paper, a long-span composite cable-stayed bridge is taken as the research object. Two kinds of finite element models considering pile–soil interaction and not considering have been established, respectively, and the elastoplastic dynamic time-history analysis based on plastic hinges has been carried out. The results show that the pile–soil interaction greatly influences the displacement response and internal force response of the cable-stayed bridge. The pile–soil interaction should be considered in the design and analysis. Furthermore, the analysis of the parameters of fluid viscous dampers between towers and beams has been presented, and the results are compared with those without dampers. The results show that fluid viscous dampers can significantly improve the longitudinal seismic behavior of cable-stayed bridges, and different damper parameters have a greater impact on the seismic response of bridges.
