钢管混凝土系杆拱桥叠合梁局部应力分析

采用ANSYS11.0,对某下承式单索面钢箱叠合梁钢管混凝土系杆拱桥的叠合梁进行了局部分析,重点关注混凝土桥面单向板和叠合梁钢板在车辆荷载作用下的应力大小和分布情况。通过实际计算分析,给出了桥面单向板在对称布载和偏载作用下产生的拉应力的范围和大小以及叠合梁钢板的最大mises应力,为相似结构的设计与施工提供参考。

Local Stress Analysis on Superposed Beam of CFST Tied Arch Bridge

Through the application of ANSYS11.0,local stress analysis is made on superposed beam of a through single plane steel box composite beam CFST tied arch bridge,and stress value and distribution of one-way slab of concrete bridge deck and steel plate of superposed beam under the effect of vehicle load are paid attention to emphatically.Through actual computational analysis,tensile stress range and value of one-way slab of bridge deck and maximum mises stress of steel plate of superposed beam under the effect of symmetrical uniform load and unbalance loading are given,providing references for design and construction of similar structure.
