摘要

:用影响矩阵考虑了桥梁在多点激振下的非线性地震响应 ,并利用 Wilsom-θ法编制了相应的程序 .该程序可用来计算非一致输入下的线性或非线性响应和一致输入下的线性或非线性响应 .通过算例对以上四种情况进行了比较 ,结果表明多点激振效应和非线性作用对结构动力响应均有较大影响 ,不容忽视
In the nonlinear respondense analysis of bridges under multi support excitation,the effect matrix and Wilson θ method are used.A corresponding program is given,which can analyze the nonlinear or linear respondense under multi support excitation and the nonlinear or linear respondence under consistent excitation.The results of numerical test compares the four cases.It can be concluded that the nonlinear and multi support excitation affect greatly on the respondense of bridge.This can't be ignored.
