Abstract

When retrofitting reinforced concrete buildings in Turkey with energy-dissipation devices, damage distribution between each story become very important, because the ultimate horizontal shear strength in each story is lower than Japanese buildings, and damage concentration at specific story is highly expected. In this paper, a retrofit concept adding elastic frames together with hysteretic dampers is introduced, and the effects of these elastic elements for damage distribution were researched and discussed, also for use in structures including weak stories. The easy damper distribution method using equivalent linearization techniques including the effect of additional elastic frames is proposed, followed by its validity evaluations.
