DESIGN AND PERFORMANCE OF PASSIVELY CONTROLLED BUILDING WITH ELASTO-PLASTIC DAMPER AT BEAM ENDS(Structures)

Abstract

Damage controlled building incorporating dampers has been popular in Japan, however, few numbers of low-rise buildings are applying this concept. One of the reason is such buildings have difficulty for incorporating brace or wall dampers. To solve this problem, authors have proposed elasto-plastic damper at beam ends, which can be replaced after large earthquake. In this paper, the varidity of this damper is velified using two practical building models, followed by the proposal for simplified response estimation method, which requires no time-history analysis.
