[摘要]以某高层钢结构为研究对象，研究此结构脉动风荷载作用下动力特性响应，并结合响应标准进行了结构舒适度评价。结果表明：结构脉动风荷载作用下结构变形属于剪切变形；结构位移响应与施加的风压时程曲线趋势相似，考虑结构不同高度处空间相关性影响，不同楼层位置位移时程影响曲线的变化趋势存在一定的差异；此结构产生的风致振动人体难以察觉。

Abstract: Taking a high-rise steel structure as an example, response of the structure to the dynamic characteristics under fluctuating wind load was studied，combined response criteria was evaluated structural comfort. The results showed that: deformation of structure under the fluctuating wind load is shear deformation; structural displacement response curve is similar to the curve of the pressure time history. Because of consider different heights the structure of spatial correlation affect, displacement positions on different floors response curves are differ. Wind-induced vibration of this structure is inconvenienced by the body.
