桥梁动力时程分析中地震波的选用

Choosing seismic wave in dynamic time-history analysis of bridge structure

针对桥梁结构抗震分析中地震波的选取进行了讨论,首先说明了正确选择地震波的重要性,指出选择地震波时应同时符合地震动三要素,结合实际桥梁工程,给出正确选择与调整地震波的具体方法与步骤。

Selection of earthquake waves for bridge structure in seismic analysis are discussed in this paper, firstly, the importance of the selec- tion of earthquake waves is narrated. Three essential factors of ground motion must be considered simultaneously, combined with engineering de- sign practice of the bridge structure, the methods to select and adjust the reasonable seismic waves are given in this paper.
