To make them meet this requirement, we propose a self-centering system composed of rocking structural members, of which part is allowed uplifting during an earthquake. This system can prevent steel building structures from yielding residual deformation after sever earthquakes by using effect of building’s self-weight. To examine seismic performance of this system, seismic response analyses are executed on a real-scale steel frame model. Numerical models to express the force-deformation relationship of the rocking structural members are presented. The self-centering ability of the system is examined and its energy dissipation mechanism is investigated. As input ground motions, the 1995 Kobe earthquake record and an artificial ground motion are used. The results of analyses cleared that the proposed system can realize the self-centering system and successfully mitigate seismic damage of buildings against severe earthquakes.
