Study on seismic behaviour for high damping rubber bearings of continuous beam bridges
[摘要] The seismic response of a viaduct has been analysed in order to investigate the seismic performance and influence of high damping rubber bearings. Nonlinear time-history method has been used to analyse the seismic behaviour of different bearings. The results show that the seismic behaviour of high damping rubber bearing was better than laminated rubber bearing under earthquakes of level E2. Laminated rubber bearing was not suitable to be used in high seismic intensity area as the oversize displacement and sliding resistance.
