Abstract
In this thesis the dynamic response of structures that are allowed to uplift, roll, and rock when subjected to ground excitation is investigated. High potential for successful mitigation of the harmful effects of earthquake ground excitation is associated with rocking structures and has been an important topic of researcher for decades.
However, the lack of relatively simple rocking structure design models, as opposed to complex response simulation models, deters from widespread use of rocking structures in earthquake engineering practice. The aim of this thesis is to try to close the gap between practicing engineers and researchers and to contribute to the understanding of the fundamental dynamics of rocking systems. A new rolling-and-rocking solution for a rocking oscillator is developed, achieved by extending its base. Show more
