| Popis: | 非構造部材の耐震性能を定量化する目的で，間仕切り壁を設置した実大鋼構造フレーム実験を行った。ドアや直行壁に対する影響を含め，その損傷過程と補修費用の関係を検証した。石膏ボードの損傷は柱梁との接触部において顕著であり，動的な載荷による損傷と静的な載荷による損傷に差異は現れなかった。層間変形角0.02rad時において，ドアは鍵部の食い込みにより完全にロックされた。層間変形角0.02radを経験すると，補修費用が初期費用に達した。 In spite of its significance in the context of performance-based earthquake engineering, quantitative information on the seismic performance of nonstructural components is very limited. From among the nonstructural components that are significant in the economic losses in buildings, interior drywall partitions are selected for an experimental program. Four full-scale drywall partitions with light-gage steel stud framing were tested to observe damage to cyclic loading conditions. Effects of a door and an intersecting wall on the behavior of drywall partition are studied. Damage was concentrated to perimeter regions where gypsum boards made contacts with ceiling, floor, or columns. Dynamic loading did not amplify the damage to a drywall partition over the damage observed from the quasi-static test. Damage-repair cost relationships show that the repair cost reaches almost the initial cost under 2% radian interstory drift. |
