Abstract
After the Hyogoken-Nanbu earthquake, building which used damper as an earthquake resistant member is increasing. The damper is used for not only new construction but also seismic repair. In case of seismic repair, strength eccentricity or stiffness eccentricity may occur in damper system by the constraint of floor planning. It become an important problem to evaluate the effect of the eccentricity in damper system on earthquake performance of building structures. In this study, in order to clarify this problem experimentally, a series of full-scale shaking table test of single story steel frame is carried out. Main parameter in this experiment is strength eccentricity and stiffness eccentricity in damper system. The experimental result showed good correspondence with the result of response analysis using the fundamental model. Therefore, it was proven that this problem could evaluate in analytical approach.
