摘　　要：为减轻地震对建筑物顶部突出部分的破坏作用及影响,作者对其进行了动力分析,得出在地震荷载作用下,结构的鞭梢效应使突出部分的振动反应加大,从而引起破坏,说明其产生的原因和条件,并为结构设计提出建议。In order to reduce the damage of earthquake analysis about the vibration of the parts when an earthquake to the prominent parts on top of a building, a dynamic would happen was made. It is proposed that, affected by the load of an earthquake, the structural whiplash effect will increase the vibration of the prominent parts, thus causing damage. The reasons and conditions causing whiplash effect are analyzed. Some suggestions are also put forward.

关 键 词：建筑结构 自由振动 鞭梢效应
