［摘要］通过研究加强层的工作机理，并结合一个超高层结构的实例，研究和分析了带加强层结构的位移角、内外筒剪力、倾覆力矩的分配、薄弱层等基本参数。结果表明，加强层能明显提高结构刚度和抗倾覆能力，减小结构位移，但易使加强层的下一层形成薄弱层。最后，给出了加强层抗震构造措施。

Abstract: The working mechanism of strengthened storey was studied. Combined with an engineering example, the basic parameters, such as storey drift, storey shear and overturn moment distributed in-out core wall, weak layer and so on, were studied and analyzed. The results show that the strengthened storey can increase the stiffness of the structure, anti-overturning moment and decrease displacement of the structure. But the storey below the strengthened one is easy to be weak. Finally, the details of seismic design in the strengthened storey were listed.

Keywords: strengthened storey; core wall; weak layer; seismic design detail
