Seismic Responses of a Cable-Stayed Bridge with Consideration of Uniform Temperature Load

摘要: The effects of temperature load on the dynamic responses cable-stayed bridges have attracted attention researchers in recent years. However, these investigations mainly focus influence characteristics structures, such as vibration mode and frequency. This paper discusses uniform changes seismic a bridge. A three dimensional finite element model bridge using OpenSees is established for nonlinear time history analysis, applied to prototype before conducting excitation. Three ground motion records are selected from PEER strong database based design spectrum. Case studies then performed considering varying connections between deck pylons result shows that significantly increased with consideration load. Meanwhile, types pylon also notable impacts without changes. research could provide reference designers during phase brides.
