潜江市兴盛路装饰拱桥布置方案及装饰拱结构力学分析

通过对拱结构与主桥的不同连接方式进行方案比选,阐明了装饰拱桥设计中需要考虑的主要因素。简要介绍了建立空间梁单元模型,并按照无铰拱对装饰拱进行力学性能验算的方法;同时根据计算结果进行结构强度、稳定性评价及静力、动力、抗震等各项力学性能分析,以确定不同参数对结构安全的影响。装饰拱布置选型方案及结构分析的研究方法可用于指导该类桥梁设计。

Layout Scheme of Decorative Arch Bridge and Mechanics Analysis of Decorative Arch Structure in Xingsheng Road of Qianjiang City

By comparing the different connection schemes between arch structure and main bridge,some main factors to be considered in the design of decorative arch bridge are expounded.The method of establishing the spatial beam element model to check the mechanical properties of decorative arch according to the unhinged arch is briefly introduced.Based on the computed result,the structural strength and stability are evaluated,the static,dynamic,seismic and other mechanical properties are analyzed,and the influences of different parameters on the structural safety are analyzed.The selection scheme of decorative arch layout and the study method of structural analysis can be used to guide the design of the similar bridges.
