对于结构的形体、质量以及竖向刚度存在突变的建筑物,地震作用时的鞭稍效应不容忽视。但在实际的设计工作中即要考虑结构的安全又要照顾结构的美观及功能。利用层间隔震技术,将隔震层设置在结构刚度、质量突变位置,使结构的上部起到类似TMD的功能,可有效的解决结构鞭稍效应问题。同时建立了动力分析模型及震动方程。
For structures with sudden changes in body shape, mass and vertical stiffness, the whip effect during seismic action can not be neglected. However, in the actual design work, we must consider the structural safety and take care of the aesthetic appearance and function of the structure. The use of the layer isolation technology, the seismic isolation layer is set in the structural stiffness, mass mutation position, so that the upper part of the structure play a similar function TMD, which can effectively solve the structural whip effect problem. At the same time, dynamic analysis model and vibration equation are established.
