摘要
以西安市某立交曲线桥为工程背景,在以往学者研究的基础上,总结了桥梁常用减隔震装置的力学特点和数值模拟方法,并运用非线性时程分析方法,研究减隔震橡胶支座对曲线桥结构内力和位移响应的影响,分析比较了普通支座与几种常用减隔震支座的抗震性能,为桥梁减隔震设计提供参考。
Taking Xi'an city some interchange auxiliary bridge as engineering background,on the basis of past research,the mechanical characteristics and numerical simulation method of the isolation device used for bridge are summarized,the effect of the nonlinear time history analysis method on the internal force and displacement response of the curved bridge is studied by using the nonlinear time history analysis method. Analysis the seismic performance of the general support and several common used to reduce the seismic isolation support,provide reference for bridge seismic isolation design.
