摘要
为了将位移风振系数应用到高耸结构设计,本文对位移风振系数的表达式进行参数分析。研究表明,位移风振系数与结构高度、地面粗糙度有关,与结构外形及结构顶底比关系不大。将相关参数制成表格,方便应用。
In order to apply the wind-induced vibration displacement coefficient to high-rise structure design,the parameters affecting the wind-induced vibration displacement coefficient were analyzed in this paper.The results indicated that the wind-induced displacement vibration coefficient is related to the structure height and the surface roughness,but not to the structure shape and the structure top-width to bottom-width ratio.Those relevant parameters were tabulated for easy design application.
