摘要
随着波形钢腹板PC组合箱梁桥在中大跨径桥梁中的应用增多,对此类桥型动力特性的研究就变得尤为重要。文章以一座跨徐洪河大跨径波形钢腹板桥梁为依托工程,基于有限元技术和相关规范要求,对该混凝土波形钢腹板PC组合连续箱梁桥的动力特性以及E1与E2作用下结构的承载力开展综合验算。结果表明,徐洪河大桥的抗震性能满足工程规范及设计要求,研究可为此类桥梁的抗震验算提供借鉴参考。
With the increasing application of PC composite box girder bridge with corrugated steel web in medium and large span bridges,the research on the dynamic characteristics of this type of bridge is particularly important.Taking a large span bridge with corrugated steel web across Xuhong river as the supported project,based on the finite element technology and related code requirement,the dynamic characteristics of PC composite continuous box girder bridge with concrete corrugated steel web and the bearing capacity of the structure under the action of E1 and E2 are comprehensively calculated.The result shows that,the anti-seismic performance of the bridge across Xuhong rive meets the engineering standard and design requirement,and the research can provide reference for the anti-seismic checking calculation of such this kind of bridge.
