Application and Problems of Hybrid Structures in Super High-rise Buildings

混合结构体系在超高层建筑中经常被采用。介绍了不同类型混合结构体系的特点和在国内外应用的工程实例,分析了外钢框架+钢筋混凝土筒体和型钢混凝土框架+钢筋混凝土筒体这两种在我国经常采用的混合结构体系的抗震性能和优缺点。在分析国内已经进行的混合结构试验研究的基础上,参考国内外工程实践,考虑抗震等多种因素,提出混合结构体系在不同抗震设防区的适用性和需进一步研究的问题。

Hybrid structures are often used in super high-rise buildings. The characteristics and the applications in China and overseas of different hybrid structures are introduced. The merits and demerits and seismic behavior about the hybrid structures of steel frame-reinforced concrete core wall and steel reinforced concrete frame-reinforced concrete core wall which are often applied in China are analyzed. On the basis of hybrid structures tests and the applications in China and overseas, considering seismic factors, the applicability of hybrid structures in different seismic fortification intensity area and the problems needed to research in the future are put forward.
