高层建筑结构侧向刚度规则性计算方法研究

Study on calculating methods of the lateral stiffness irregularity of tall building structures

GB50011-2001《建筑抗震设计规范》提出的"层间剪力位移比"的计算方法对侧向刚度规则性的判断存在局限性,在一些特殊情况下会得出不正确的结论,为了解决侧向刚度规则性判断的问题,提出了"层间剪力位移角比"的侧向刚度计算方法,结合算例可以看出,对于以弯曲变形为主的结构,此方法结构概念明确,得出的结论符合工程经验,是对规范方法的很好的补充。

The calculating method of story ratio of shear and drift which is provided by ＂Code for seismic design of buildings＂ has limitation of judgement on lateral stiffness irregularity,the wrong conclusion is given in some special conditions,in order to dissolve the problem of judgement on lateral stiffness irregularity,the calculating method of story ratio of shear and drift angle is provided,based on calculating examples,the structural concept of the method is clear,the conclusion given by the method is fit to engineering experience to the structures primarily with bending deformation,it＇s a good supplement to the code method.
