摘要
以某地道桥为背景,利用ANSYS有限元软件分析了加设横梁对地道桥结构的力学影响,分析结果表明,加设横梁改变了顶板双向支撑为三向支撑,由于局部刚度的过度增大,对整个结构产生了不利影响。
Combined with one underpass bridge,using ANSYS software mechanical influence of frame underpass bridge with cross beam is analyzed.The amalying result shows,adding frame beam changes top slab from bidirectional support to tri-directional support,so the local stiffness augment and the whole bridge is affected unfavorably.
