Popis: Previous studies of rocking frame systems have established their ability to resist earthquake ground motions by transforming the input energy into potential energy through uplift of the building self weight and damping out the motions through energy dissipating devices. These rocking systems are effective to minimize the residual deformation after shake and prove the resilience of a building after big earthquakes; however they have difficulty to apply to low-rise buildings because there is not enough self weight to overcome the reaction forces of energy dissipation devices. In this paper, a concept of controlling rocking deformation with additional post-tensioning (PT) wires is proposed, and its performance under various intensity levels of earthquake motions is confirmed by large-scale shaking table tests using a universal inertial mass "Testbed" system.
