摘　　要：以某超高层钢结构中箱形截面柱的钢支架支撑结构为研究对象,应用SAP2000有限元软件建立钢支架的模型,通过施加合理的边界条件对钢支架仿真模拟,进行屈曲计算分析;屈曲分析完成后,对整个支撑结构进行了进一步的优化研究,得出了合理的优化结果,解决了施工单位关心的结构屈曲等安全性问题。This paper deals with steel bracket simulation and buckling analysis by applying reasonable boundary conditions and building the steel bracket model by SAP2000,takes the steel bracket support structure of the box columns in super high-rise steel structure as the research object.Following buckling analysis,this paper conducts further optimizaton study on the whole support structure to obtain reasonable optimization results and solve security problems like structural buckling concerned by construction units.
