ガセットプレートの存在が周辺部材の力学挙動に及ぼす影響: ダンパーを絤み込んだ靭性骨絤の総合的な耐震性能の向上　その2

摘要

The majority of experimental studies on damage-controlled structures have tested isolated dampers or simple subassemblages which neglect the influence of the framing components and the gusset-plate on the system performance. In this paper, cyclic loading tests of six frame subassemblages with the gusset-plate connection to investigate effects of the presence of the gusset-plate on structural behavior of the beam. The gusset-plate led to increase in initial elastic stiffness and yield strength of the beam. Meanwhile, damage to beam-column joint panel subjected to high shear stress was decreased by the gusset-plate. Finally, based on the cyclic loading tests of the beam with the gusset-plate connection, the simplified analysis model considering the gusset-plate working as a knee brace was proposed.%損傷制御構造は地震時のエネルギー吸収を座屈拘束ブレース に代表されるダンパーに期待し，柱梁からなる主架構を弾性ま たは限定された塑性変形の範囲に留めようとするものである． エネルギー吸収を期待するダンパーについては実大部材を含め た数多くの実験が行われ，その性能が確認されてきた．
