000011096 520__ $$2eng$$aThe Buckling Restrained Brace (BRB) was developed in Japan at the end of 1980, and had been used as a typical hysteresis damper, which absorbs an input earthquake (EQ) energy as a plastic strain energy, when inserted in Moment Frames (MF)． Another application of BRB (recently observed in United States or Asia) is a special class concentric brace, which gives seismic resistant capacity or horizontal stiffness to frames. There are wide varieties of behavior in Buckling Restrained Braced Frames (BRBF), however, they highly depend on the participant ratio of BRB (β: the horizontal load sharing ratio of BRB). An effective application of BRB is that the EQ damage concentrates (the maximization of plastic strain energy or cumulative plastic deformation ratio) to the BRB. However, it is not so easy to realize a desired damage distribution especially in a multi-story BRBF in order to prevent damage concentration to specific stories. This paper aims to evaluate the damage concentration phenomena through elasto-plastic dynamic response analyses for middle-rise steel BRBF by trial modeling with some levels of βas the main parameter.
