A seven spans of 40m T - beam high pier bridge is studied in this paper. By utilizing the finite ele- ment 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 u- sing the nonlinear time history method. The results indicate that structural earthquake -resistance performance can be improved by using seismic isolation bearing.
