摘要
南京中航科技大厦A楼塔楼采用钢筋混凝土框架-核心筒结构体系,裙房为框架-剪力墙结构体系。本文介绍了该项目的结构布置与结构体系的特点、结构超限情况和对应的抗震设计性能目标,以及多遇地震和风荷载作用下结构的整体弹性分析;对裙房楼板局部开大洞进行了应力分析,并补充整体结构静力弹塑性推覆分析;最后,提出对应的结构抗震加强措施。
The main tower of Building A of Nanjing China Aviation Science and Technology Building in Nanjing adopts reinforced concrete frame-core tube structure system,and the podium is frame-shear wall structure system.This paper introduces the structural arrangement and characteristics of the structural system,the out-codes instance and the corresponding seismic design performance target,as well as the overall elastic analysis of the structure under frequent earthquakes and wind loads;carries out the stress analysis of the partial opening of the skirt floor,and supplements the static elastic-plastic pushover analysis of the whole structure;finally,puts forward the corresponding structural seismic strengthening measures.
