摘要
层间位移限值是钢筋混凝土超高层结构设计中的一个重要参数。本文对国内外规范的层间位移限值进行了比较 ,分析了限制层间位移的目的 ,并提出了一个新的层间变形参数———区格广义剪切变形。为研究这一问题 ,进行了一个11层框架 剪力墙模型的静力加载试验 ,并对不同高度和结构形式的9幢超高层建筑进行了计算和分析。试验研究和计算分析均表明 。
The limit value of interstory drift is an important parameter for the design of reinforced concrete super highrise buildings.In this paper,the limit values in different building codes at home and abroad are compared, the aim of limiting interstory drift of highrise buildings is analyzed, and a new parameter——generalized shear deformation of region is presented.In order to study this problem,a statical loading test of an 11 story frame shear wall model is carried out,and 9 super highrise buildings with different heights and structural forms are computed and analyzed.It is proved by the experiment and analysis that 1/500 is a suitable limit value of interstory drift of reinforced concrete super highrise buildings.
