城市梁桥装饰三角桁架拱设计方案及受力分析

Design Scheme and Force Analysis of Decorative Triangular Truss Arch of Urban Beam Bridge

文中通过对装饰拱结构的设计计算分析,简要介绍了全桥的空间有限元模型,并按照无铰拱对装饰拱进行受力分析计算,同时根据计算结果,对结构强度、稳定性及静力、动力等各项力学性能进行评价,以确定各工况下结构的安全性。该装饰拱设计方案及结构分析的研究方法可用于指导该类桥梁设计。

Based on the design calculation and analysis of the decorative arch structure,the paper briefly introduces the spatial finite element model of the whole bridge,and analyzes and calculates the force of the decorative arch according to the hingeless arch.At the same time,according to the calculation results,the structural strength,stability,static,dynamic and other mechanical properties are evaluated to determine the safety of the structure under various working conditions.The design scheme of decorative arch and the research method of structural analysis can be used to guide the design of this kind of bridge.
