摘要
某高层办公楼中间部分形成跨度32.4 m的大跨度连体,连体区利用幕墙的建筑布置,采用由交叉斜撑组成的拱架(幕墙拱)全钢结构连体。针对此复杂结构,进行了抗震性能设计、整体稳定分析及变形分析、楼板应力分析及温度内力分析、楼盖舒适度分析、施工阶段分析,并对关键节点进行有限元分析。分析结果表明,结构设计满足要求,所采取的设计方法合理可行。
The middle part of a high-rise office building forms a large-span conjoined body with a span of 32.4 m.The conjoined area uses the architectural arrangement of curtain walls and adopts an all-steel structure conjoined with an arch(curtain wall arch)composed of cross bracing.For this complex structure,seismic performance design,overall stability analysis and deformation analysis,floor stress analysis and temperature internal force analysis,floor comfort analysis,construction stage analysis,and finite element analysis of key nodes are carried out.The analysis result shows that the structural design meets the requirements and the design method adopted is reasonable and feasible.
