Outline of Final Research Achievements

We focused on a buckling-restrained brace (RBR) that is a kind of seismic device and verified the ultimate behavior under quite huge ground motion worried about the occurrence in the recent decade by cyclic loading test using innovative bidirectional loading equipment. Further, effects of various triggers of strength deterioration of members, including the ultimate behavior of BRB, in steel moment-resisting frames with BRBs were clarified by time history analysis.

Academic Significance and Societal Importance of the Research Achievements

これまでに検討が不十分であった,水平2方向の大変形を受ける座屈拘束ブレースの終局挙動を明らかにしたこと,ならびにそれを適用した鋼構造骨組の倒壊挙動を確認したことは学術的に大きなブレークスルーポイントであると考える.
