摘要
某大跨办公楼属于多项不规则的多层钢框架结构,建筑位于上海普陀区,7度设防,为满足建筑效果要求,塔楼北侧区域在3层—5层设有长36 m的大跨空腹桁架和9 m的悬挑,支承在V型斜柱上,另外塔楼设置通高的楼板大开洞。针对该工程结构特点,采用多种有限元软件进行一系列弹性计算及弹塑性分析,并合理设置施工顺序,确保结构满足抗震性能目标。
Design on a large-span steel structure is discussed in this paper.The project is located in Putuo District Shanghai,7 degree zone.In order to meet the requirements of the building effect,the north side of the tower is equipped with 36 m long fasting trusses and 9 m overhangs on the V-shaped inclined columns on the 3rd to 5th floors.In addition,the tower is equipped with big floor holes in the plane.According to the structural characteristics of the project,a series of elastic calculation and elastic-plastic analysis are carried out by using a variety of finite element software,and the construction sequence is set reasonably to ensure that the structure meets the seismic performance target.
