摘要
对上海成都路和延安路高架立交桥进行了非线性地震反应分析,从而对其抗震安全性作出评价,并提出合理建议.在分析中,考虑了四层高架结构在地震时的耦合振动作用,以及地震波传播方向的任意性.
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.
