深圳前海国际金融中心无梁空芯大板超高层建筑结构设计

Design of super high-rise building structure of hollow large slab without beam in Shenzhen Qianhai International Financial Center

深圳前海国际金融中心是国内首次在超高层建筑中采用无梁空芯大板楼盖的建筑,结构采用带加强层的型钢混凝土(SRC)巨柱框架-核心筒形式。进行了结构方案选型及基础设计,详细介绍了结构体系组成、结构布置及采取的加强措施;进行了小、中、大震及风荷载作用下的计算分析,结果表明,结构能满足预定的性能目标要求;最后着重介绍了无梁空芯板模拟、结构加强层方案选择和复杂节点分析设计等内容。

Shenzhen Qianhai International Financial Center is the first building to adopt hollow large slab floors without beam in super high-rise buildings in China.The structure form is the steel reinforced concrete(SRC)huge column framecore tube with reinforced floors.The structural scheme selection and foundation design were carried out.The structure system composition,structure layout and strengthening measures were introduced in detail.The calculation and analysis under the action of frequent earthquakes,occasional earthquakes,rare earthquakes and wind load were carried out,and the results show that the structure can meet the predetermined performance requirements.Finally,the simulation of hollow slab without beam,the selection of structural strengthening layer scheme and the analysis and design of complex joints were mainly introduced.
