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。 By studying the working mechanism of strengthening layer and combining with an instance of super high-rise structure, the basic parameters of displacement angle, inner and outer tube shear force, overturning moment distribution and weak layer are studied and analyzed. The results show that the strengthening layer can obviously improve the structural rigidity and anti-overturning ability and reduce the structural displacement, but it is easy to make the next layer of the reinforcing layer to form the weak layer. Finally, some measures to strengthen the earthquake resistance of the structure are given.
