【摘要】：以青島地鐵人民路節(jié)點(diǎn)橋連續(xù)U梁設(shè)計(jì)為依托,對(duì)現(xiàn)有常規(guī)連續(xù)U梁截面進(jìn)行優(yōu)化。利用BSAS程序,對(duì)2種不同截面的連續(xù)U梁通過平面桿系模型進(jìn)行計(jì)算對(duì)比,得出2種截面下全橋的變形和受力分析。在Midas中建立有限元實(shí)體模型,對(duì)優(yōu)化截面連續(xù)U梁計(jì)算結(jié)果進(jìn)行復(fù)核對(duì)比,對(duì)今后軌道交通中連續(xù)U梁結(jié)構(gòu)設(shè)計(jì)提供參考,并對(duì)結(jié)構(gòu)的優(yōu)化設(shè)計(jì)提出建議。
[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.
