［摘要］分析了我国JZ 102—79，JGJ 3—91，JGJ 3—2002，JGJ 3—2010等历次高规关于高层建筑结构层间位移角规定限值的演变过程，对影响楼层结构层间位移角计算结果的各种因素，如风荷载取值、是否考虑结构重力二阶效应、是否考虑地下室、计算模型中一些假定和结构构件刚度折减系数等进行了讨论。在分析结构中上部楼层的层间位移角大部分是由结构构件底端转动引起的非受力位移组成的基础上，提出了各类高层建筑风荷载作用下最大层间位移角限值取1/500的建议，并提出当采用阻尼器等减振措施满足舒适度要求时或考虑地下室竖向构件变形时层间位移角限值可适当放松的合理建议,可供规范修订和工程设计参考应用。

Abstract:The evolution process of limit values of inter-story displacement angle in the previous technical specifications for concrete structures of tall building (JZ 102—79, JGJ 3—91, JGJ 3—2002 and JGJ 3—2010). Various factors affecting the calculation results of inter-story displacement angle, such as the wind load value, the P\|Δ effect of structural gravity, influence of the basement, some assumptions in the calculation model and the stiffness reduction coefficient of structural members were discussed. Based on the analysis that most of the inter-story displacement angle is composed of the non-forced inter-story displacement caused by the rotation at the bottom of the vertical structural members, the suggestion was proposed that the maximum limit value of the inter-story displacement angle under the wind load of various high-rise buildings should be taken as 1/500, and the  limit value of inter-story displacement angle  can be properly relaxed when adopting the damping measures such as dampers to meet the comfort requirements or considering the deformation of the vertical members in the basement. These suggestions can be used for the revision of relevant code and the reference for application of engineering design.

Keywords:high-rise building; inter-story displacement; forced inter-story displacement; non-forced inter-story displacement; limit value of inter-story displacement angle
