钢筋混凝土超高层建筑层间位移限值的探讨

Discussion on Story Drift Limit of SuperHigh-rise Reinforced Concrete Buildings

高层建筑结构设计中层间位移值是一个重要的参数，但是对于超高层建筑目前还无规范可以遵循。本文通过对层间位移组成的分析，提出了设计建议值供大家讨论。

The story drift is one of the major factors to be considered in planning and design of tallbuildings, as it may affect the general stability of the strUcture, the performance of non-structuralelements and the comfort to occupants. The story drift limitations for super high-rise building can notyet be found in the present Chinese codes. The story drift limits in foreign codes are intorduced andthe composition of the lateral deflections have been analyzed and discussed in the paper in order toprovide references for reasonable story drift limits for super high-rise buildings.
