[摘要]以某高層鋼結構為研究對象，研究此結構脈動風荷載作用下動力特性響應，并結合響應標準進行了結構舒適度評價。結果表明：結構脈動風荷載作用下結構變形屬于剪切變形；結構位移響應與施加的風壓時程曲線趨勢相似，考慮結構不同高度處空間相關性影響，不同樓層位置位移時程影響曲線的變化趨勢存在一定的差異；此結構產生的風致振動人體難以察覺。

[關鍵詞]高層鋼結構；脈動風荷載；舒適度；剪切變形；空間相關性

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.
