| Abstract: | A computer program is compiled with C language codes to calculate the two-line hysteresis model of the pier members of a cable-stayed bridge under strong earthquake motion. Then a whole bridge FEM model is established by ANSYS, dynamic character and nonlinear time history analysis are made based on the hysteresis model. Conclusions are made from the result for the seismic behavior of the bridge, and some advice is given for the design of this kind of bridge. |
