【Abstract】 The nonlinear earthquake response of the interchange bridge, situated at the crossing of Chengdu Road Viaduct and Yan’an Road Viaduct was analysed. Then the safety of the bridge Under earthquake was evaluated, and a rational suggestion was made. In the analysis, both the coupled vibration of four level structures under earthquake and the randomness of spread directions of input seismic waves were considered.更多还原
