摘　　要：曲线梁桥的应用在城市桥梁和高速公路中愈来愈普遍了,从结构动力学的观点研究它的结构特性和地震反应越来越迫切。针对北京天宁寺立交二环路主桥,用理论与实验相结合的方法对该桥动力特性及其地震响应进行了深入研究。In this paper, a study of the seismic response of curved bridges is conducted. Between the in-situ responses and analysis results, mode shapes, mode frequencies were evaluated. Using E1-Centro earthquake accelerogram, differ- ent seismic loading are examined. The results of a nonlinear analysis of the seismic response of curved bridge are presented.
