| Abstract: | A seven spans of 40m T-beam high pier bridge is studied in this paper.By utilizing the finite element software,a three-dimensional mechanics model is established.Based on the model,seismic behavior of T-beam high pier bridge,in which various support links between pier and beam are considered,is investigated by using the nonlinear time history method.The results indicate that structural earthquake-resistance performance can be improved by using seismic isolation bearing. |
