BRBs are now extensively used to control the seismic demand (response) of building structures in Japan. However a few studies have so far been made on BRBs installed in bridge structures. In this paper, an outline of BRBs is first described, followed by a presentation of a numerical model for determining the elasto-plastic cyclic behavior of BRBs. Then, an attempt is made to substantiate the numerical approach by comparing its results with some experimental results. Lastly, a list of six important required performances are presented,some of them being examined numerically. As a result, empirical formulas have been proposed for (a) limit of spacing between the bracing and restraining member and (b) contact force transmitted to the restraining member.}, pages = {527--538}, title = {制震ダンパーとしての座屈拘束ブレースの要求性能}, volume = {50A}, year = {2004} }
