摘要
PC斜拉桥宜采用时程分析法进行抗震性能分析,时程分析中一些参数的选择会对分析结果产生较大影响,为合理地考虑这些影响因素,以具有实际工程意义的370 m跨径PC斜拉桥为研究对象,系统地进行地震响应分析,并根据分析结果对地震作用下结构动力特性的特点提出设计建议。
The PC cablc-stayed bridge should be analyzed by using the time-history method. The result of time-history analysis may be influenced by several parameters that should be adequately considered. In this paper , the span of 370 meters PC cable-stayed bridges is analyzed by using the time-history method. Detailed suggestions on how to choose these influencing factors and to design by the results of finite element method are put forward.
