| Research Abstract |
The steel frames with uplift column-bases are implemented as response-control structural systems that reduce the seismic effects by exploiting the gravity effect generally deteriorating the seismic performance of ordinary structures. The reduction effect on the seismic response of the base-plate-yielding (BPY) rocking systems with columns allowed to uplift has been evaluated and examined. The advantages and disadvantages of the systems have also been discussed. This study presents the seismic response characteristics with emphasis on the torsional behavior of the BPY systems and proposes the advanced rocking systems resolving the disadvantage of the BPY systems towards developing and applying widely the rocking structural systems. Finally, some suggestions and recommendations are made on the seismic design of the rocking systems.
