局部隔震对结构鞭梢效应的控制作用

提出了一种局部隔震结构模型，建立了其振动方程，通过时程分析研究了鞭梢效应对主体结构和塔楼的影响，并利用局部隔震措施来控制鞭梢效应．研究表明，用增加塔楼刚度的方法来抑制鞭梢效应会使主体结构的地震响应增加，而通过在主体结构和塔楼之间设置隔震装置进行局部隔震，不仅能有效地抑制鞭梢效应，还能够大幅度降低主体结构的地震响应，且主体结构的地震响应减小约40％．

Study on Using Part Isolation to Control Structural Whipping Effect

A part isolation structure model was presented with its dynamic and vibration equations established. The influence of the whipping effect upon the main structure and the tower building was researched using time history analysis and the measure of part isolated was used to control whipping effect. The conclusions suggest that the measure of increasing tower building rigid degree to control whipping effect can increase the earthquake response of the main structure too.The using part isolation can not only reduce whipping effect but also reduce the earthquake response of the main structure visibly. The earthquake response of the main structure can lower to 40%.
