| dc.description.abstract | Rocking walls are an effective method of dissipating seismic response energy and mitigating damage. Semi-active resetable devices have shown significant potential to dissipate energy, customize hysteretic behavior and reduce damage. Hence, the addition of a resetable device within a rocking wall can further improve the overall energy management during seismic events. A scaled semi-active rocking wall system, designed for a large open structure, is analysed using real-time, high-speed hybrid testing. The semi-active devices are controlled to provide supplementary resistance only for the upward rocking motion of the wall, providing semi-active energy dissipation over half of each cycle and relying on radiation damping for the other half. An validated model of the semi-active devices is used to examine the response of a full scale rocking wall system to a suite of earthquake ground motions to prove the overall concept. Overall, similar semi-active rocking walls could also be used as supplemental, low-footprint response energy management systems in retrofitting a variety of structures. | en |
