| 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 in Qingdao Renmin Road,this paper optimizes the cross section of the conventional continuous U-beam. Based on BSAS program,two types of continuous U-beam with different cross section are calculated and compared by means of the model of plane bar system to obtain the deformation and stress of the whole bridge with two cross-section U-beams. A finite element model is established in Midas to review and compare the calculation results of the continuous U-beam with optimized cross-section,which will provide reference for the design of \ continuous U-beam structure in future rail transit and propose the optimal design of structure. |
