【摘要】：以青岛地铁人民路节点桥连续U梁设计为依托,对现有常规连续U梁截面进行优化。利用BSAS程序,对2种不同截面的连续U梁通过平面杆系模型进行计算对比,得出2种截面下全桥的变形和受力分析。在Midas中建立有限元实体模型,对优化截面连续U梁计算结果进行复核对比,对今后轨道交通中连续U梁结构设计提供参考,并对结构的优化设计提出建议。
[Abstract]:Based on the continuous U beam design of the joint bridge of the people's Road of Qingdao Metro, the section of the conventional continuous U beam is optimized. By using BSAS program, two kinds of continuous U beams with different sections are calculated and compared through the plane bar system model, and the deformation and force analysis of the whole bridge under the two different sections are obtained. The finite element solid model is established in Midas, and the calculation results of continuous U beam with optimized section are checked and compared, which provides a reference for the design of continuous U beam structure in rail transit in the future, and puts forward some suggestions for the optimization design of the structure.
