摘　　要：对建筑物上附属构筑物在风荷载作用下所产生的振动进行了分析,得出在风荷载作用下,附属构筑物的动力系数β=2,从而引起附属构筑物的破坏,对此类构筑物的设计提出建议。Vibration of supplementary structures of a building under wind load was analyzed. It was calculated that the dynamic factor β was two which could lead to damage of the building. Some suggestions for the construction of such structures are proposed.

关 键 词：单自由度 自由振动 受迫振动 动力反应
