摘要

以贵州虎跳河特大桥为工程背景,利用有限元程序ANSYS建立动力分析模型,进行连续刚构桥动力特性分析、反应谱分析以及动力时程响应分析。结果表明,不同方向地震波输入对动力时程响应分析影响较大,采用反应谱方法较动力时程响应分析安全。
Taking the under construction approach bridge of Hutiao River large bridge in GuiZhou province as the engineering background,a dynamic model for it is established and modal response analysis,spectrum response analysis and time-history response analysis are made by Finite Element Method.The modeling method and the dynamic results in this paper lead to the conclusion that the response under combination input of shock from different orientations is different,and the spectrum response analysis is more secure than time-history response analysis.
