【摘要】 以福建省永春县上坂大桥为工程背景,针对无伸缩缝桥梁的结构特点,提出一个土-结构的非线性相互作用模型。在此基础上建立有限元模型,采用谱分析法和时程分析法研究该桥的地震响应,研究结果可为无伸缩缝桥梁的抗震设计提供理论依据。更多还原

【Abstract】 In this paper,on the basis of Shangban Bridge a nonlinear soil-structure interaction model of joint-less bridges is presented according to its structural characteristics. Then the finite element model of a joint-less bridge is built,based on this. The seismic response of jointless bridge is examined by spectrum analysis method as well as transient analysis method. The results can help the anti-seismic design of jointless bridges.更多还原
