摘　　要：超长大跨度钢结构应设置结构缝进行分区设计分析。论文对超长钢结构屋盖分缝后的端部进行设计分析总结,将端部屋盖结构的中部支座设计为固定铰支座,其他支座设计为横向固定的纵向弹性支座,既能有效减少结构沿纵向的温度效应,又能满足结构整体的刚度要求。采用3D3S设计软件对网架进行结构设计,并采用Midas设计软件对航站楼进行计算校核,根据柱顶节点位移判定整体结构的水平刚度是否满足相应的规范设计要求。Ultra-long and long-span steel structures should be equipped with structural joints for zoning design analysis.This paper analyzes and summarizes the design of the end of the ultra-long steel roof structure after splitting.The middle support of the end roof structure is designed as a fixed hinged support,and the other supports are designed as a longitudinal elastic support with transverse fixation,which can not only effectively reduce the temperature effect of the structure along the longitudinal but also meet the stiffness requirements of the whole structure.3D3S design software is used to design the grid frame,and Midas design software is used to calculate and check the terminal building,according to the displacement of column top joints,the horizontal stiffness of the whole structure can be determined to meet the corresponding design requirements.
