摘要
介绍了地震反应分析的基本理论,以西安市某立交辅道桥为工程背景,对预应力混凝土连续曲线梁桥进行了反应谱分析和非线性时程分析,探讨了地震作用下曲线桥梁的动力特性,据此提出了曲线梁桥的抗震设计建议。
With an introduction of basic theories of seismic response analysis,taking the auxiliary bridge of the overpass in Xi＇an as the engineering background,the paper carries out response spectrum analysis and nonlinear time-history analysis of the prestressed concrete continuous curve bridge,explores the dynamic properties of curve bridge under seismic action,and finally puts forward the seismic design suggestions of the curve bridge.
