摘　　要：超高层建筑航天工研院在21层设置了空中大堂,为实现镂空轻巧创意,配合玻璃幕墙竖向风格,结构采用钢吊杆悬挂空中大堂的楼盖。采用弹性屈曲分析法对穿层柱、穿层墙的稳定性进行了研究;采用PMM屈服球对穿层柱的正截面承载力进行了验算;采用弹塑性时程分析法对穿层墙的承载力进行了复核;采用行走激励振动响应分析法对空中大堂悬挂楼板进行了舒适度分析;采用应力分析方法对悬挂楼板的承载力性能进行了评定;采用性能化设计方法对悬吊空中大堂的钢吊杆的承载力进行了验算;采用弹塑性时程分析方法对吊挂梁进行了承载力验算。结果表明:穿层柱、穿层墙的稳定性满足规范要求;悬挂楼板的自振频率及竖向加速度满足舒适度要求;钢吊杆的选型合理可靠;穿层柱、穿层墙、悬挂楼板、钢吊杆及吊挂梁的承载力均能满足既定的抗震性能目标要求;采用的结构方案不仅较好地实现建筑创意,而且空中大堂的结构设计安全可靠,合理可行。The sky⁃lobby is set up on the 21st floor of the super high⁃rise building of Shenzhen Aerospace Industry Technology Research Institute.In order to realize the creation of hollowing out and lightness,the structure adopts the floor of the sky⁃lobby suspended by the steel suspender with the vertical style of the glass curtain wall.The stability of through⁃story columns and through⁃story walls was studied by elastic buckling analysis.The normal section bearing capacity of the column was checked by PMM yield ball.The elastic⁃plastic time history analysis method was used to review the bearing capacity of the through⁃story wall.The walking excitation vibration response analysis method was used to analyze the comfort of the suspended floor in the sky⁃lobby.The bearing capacity performance of the suspended floor was evaluated by stress analysis method.The performance⁃based design method was used to check the bearing capacity of the steel suspender of the suspended sky⁃lobby.The elastic⁃plastic time history analysis method was used to check the bearing capacity of the hanging beam.The results show that the stability of the through⁃story column and the through⁃story wall meets the requirements of the specification;the natural vibration frequency and vertical acceleration of the suspended floor meet the comfort requirements;the selection of steel suspender is reasonable and reliable;the bearing capacity of through⁃story columns,through⁃story walls,suspended floors,steel suspender and hanging beams can meet the requirements of the established seismic performance objectives.The structural scheme adopted not only better realizes the architectural creativity,but also the structural design of the sky⁃lobby is safe,reliable,reasonable and feasible.
