摘要
将大跨度悬索拱桥简化为空间有限元计算模型,采用人造地震波在3个正交分量同时作用,分析了悬索拱桥几何非线性响应规律,并对行波效应和相干损失的影响行了比较分析,结果表明在考虑相干损失和行波效应的地震激励下,结构的响应量比仅考虑行波激励的结果较大。
Simplifying long span suspension arch bridge （SAB） as a spatial finite element model subjected to three orthogonal artificial earthquake waves simultaneously, nonlinear response of SAB is analyzed.Moreover, effects of traveling wave excitation and interactive dissipation are compared. The analysis indicated that the responses to the seismic waves with both causes considered are larger than those to traveling wave effect excitation.
