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,并运用时程分析法计算了该桥在纵向、横向和纵向+横向有地震输入时的地震响应,分析了该桥对不同地震反应的受力特点和规律性,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 studied in this paper,and the dynamic characteristics of this large span half-through arch bridge are calculated and analyzed by using a three-dimensional finite element model.In addition,three-dimensional seismic response of this bridge is obtained by the use of time history method.The effects of the longitudinal,the cross and the longitudinal+cross direction input of earthquake motion on seismic response of this bridge have been discussed.This study provides a theoretical basis for the seismic design of large span half-through arch bridge with concrete filled steel tube ribs.
