In the present study the seismic response of elastic single degree of freedom oscillators placed on the top of a rocking storey is examined. A storey comprised of columns that may uplift under ground motion excitations can be regarded as an innovative and cost effective base isolation technique. Regarding the podium structural systems, apart from studying the rocking response in order to avoid the rocking overturn, it is important to examine the seismic demand on the superstructure so as to assess the rocking storey as base isolation system. From this point of view, structural as well as ground motion parameters that affect the seismic demands of the superstructure are examined. For this purpose, the superstructure’s response spectra, of various structural configurations, under free rocking response, analytical pulses and natural ground motions are presented and discussed. Finally, the effect of different assumptions regarding energy dissipation during impact on the response of the superstructure is investigated. The study of the podium structures results in useful remarks concerning the performance of the rocking storey as a base isolation system.

在本研究中，研究了放置在摇摆层顶部的弹性单自由度振荡器的地震响应。由在地面运动激励下可能会升起的圆柱构成的层可以被认为是一种创新且具有成本效益的基础隔离技术。关于讲台结构系统，除了研究为避免晃动而发生的晃动响应外，重要的是检查上部结构的地震需求，以评估作为基础隔离系统的晃动层。从这一观点出发，研究了影响上层建筑抗震要求的结构以及地面运动参数。为此，在自由摇摆响应下，各种结构构型的上部结构的响应谱，提出并讨论了分析脉冲和自然地震动。最后，研究了不同假设对冲击过程中的能量耗散对上部结构响应的影响。对讲台结构的研究得出了有关摇摆层作为基础隔离系统的性能的有用评论。
