中承式钢管混凝土拱桥的地震响应分析
|
摘要
以福建省某大跨度中承式钢管混凝土拱桥为研究对象,通过建立空间结构有限元分析模型,计算和分析了该中承式大跨度钢管混凝土拱桥的动力特性,并分别运用反应谱法和时程分析法计算了该桥在纵向、横向地震动输入下的地震响应,对其抗震性能进行了分析和评价,并比较不同分析方法下结构地震反应的差异,本文研究将为大跨度中承式钢管混凝土拱桥的抗震设计提供理论依据.
A large-span half-through arch bridge with concrete filled steel tube ribs arch ribs located in Fujian Province was examined in this paper,and the dynamic characteristics of this large span half-through arch bridge were calculated and analyzed by using a three-dimensional finite element model.In addition,three-dimensional seismic response of this bridge was obtained by the use of response spectrum method and time history method respectively.The seismic response effects of this bridge were discussed in detail by subjecting this bridge to earthquakes in the out-of-plane direction,longitudinal direction and combined out-of-plane and longitudinal directions respectively.This study provides a theoretical basis for the seismic design of large span half-through arch bridge with concrete filled steel tube ribs.
