波形钢腹板PC组合连续箱梁桥有限元静力分析

摘要

According relying built a Bridge (47 m +52 m +47 m) corrugated steel webs PC combination of multi-span continuous box girder bridge as the background of static mechanical properties of the bridge as a whole, in accordance with the operator after the completion of the bridge in the finite element analysis, validationthe stress of the concrete floor and roof of the upper structure of the bridge-type structure, structural stiffness, crack resistance under the long-term and short-term effects of combination can meet the requirements of the current specification, the results show that the finite element model in a variety of workcombination of conditions, the structure can well meet the requirements.%以建成的某大桥(47 m+52 m+47 m)波形钢腹板PC组合多跨连续箱梁桥为背景,按照桥梁在建成后的运营对桥梁的整体的静力学特性进行有限元分析,验证这种桥型结构的上部结构的底板和顶板的混凝土的应力、结构刚度、抗裂性能在长期和短期的效应组合下能否满足现行的规范的要求,结果表明其有限元模型在各种工况的组合下,结构能够很好满足规范和设计文件的要求.
