［摘要］保利未来科技城北区项目为五塔连体的复杂超高层建筑工程，塔楼结构高度96-7～140-0m不等。该工程地下共4层，地上各栋塔楼采用钢筋混凝土框架-核心筒结构体系或者型钢混凝土框架-核心筒结构体系，裙房采用钢筋混凝土框架-剪力墙结构体系。地上五栋塔楼通过滑动连接形成三个相对独立的单体或者连体，其中A1-A2双塔连体、A3单体、A4-A5双塔连体均为超限高层结构。详细介绍了该项目的结构特点及设缝情况，以A1-A2双塔连体为例论述了结构体系、超限情况、抗震性能目标以及主要计算结果；同时研究了连接体竖向地震反应的计算方法。结果表明结构满足相应的性能目标要求。

Abstract:The north district project of Poly Future Science and Technology City is a complex super high-rise building with five towers connected. The height of towers ranges from 96-7m to 140m. The project has four floors underground. The upper towers are reinforced concrete frame-core tube structure system or steel-reinforced concrete frame-core tube structure system. The podium is reinforced concrete frame-shear wall structure system. The five towers form three independent twin-tower unit or single-tower unit  by sliding joints, of which A1-A2 twin-tower unit, A3 single-tower unit, A4-A5 twin-tower unit are all out-of-code high-rise structures. The structural characteristics and seismic joints were introduced in detail. The structure system, out-of-code conditions, seismic performance objectives and seismic calculation results were discussed by taking the A1-A2 twin-tower unit as an example. The calculation method of the vertical seismic response of the connection was studied. The results show that the structures meet the corresponding performance objective requirements.

Keywords:super high-rise; connective structure; seismic performance; vertical earthquake
