摘要
悬索跨越管桥是一种低柔性和高阻尼结构体系,地震作用在这类结构的设计中起控制作用。本文以某悬索跨越管桥工程结构为例,利用有限元软件ANSYS建立悬索跨越管桥结构的有限元模型,进行三种地震波作用下的时程响应分析,获得节点的位移时程响应及单元的最大应力值,结果表明该悬索跨越管桥结构在地震作用下是安全的,为同类结构的抗震设计提供参考。
The suspension cable spanning pipeline is a kind of low flexibility and high damping structure system which plays a vibration-control role in anti-seismic design. In this paper, finite element software ANSYS was used to establish finite element model of the suspension cable spanning pipeline structure for three kinds of seismic waves to analyze the time-history response, obtain the node displacement time history response unit and the maximum stress value. The results show that the suspension cable spanning pipeline structure under seismic action is safe, which provides reference for seismic design of similar structures.
