Seismic response analysis of a long-span cable-stayed bridge under random seismic excitations with spatial variations, including travelling effect, incoherence effect and local site effect, was made with stochastic method.

• 摘要以南京第二长江大桥南汉桥为例，采用随机振动分析方法研究了地震动的空间变化特性，包括行波效应、部分相干效应以及局部场地效应对大跨度斜拉桥地震响应的影响。
