鉄筋コンクリート造有開口耐カ壁の構造性能の評価に関する研究【安全·安心】

摘要

耐震要素として広く利用される鉄筋コンクリート造耐カ壁には、建築設計上の要求により、開口が設けられることが多い。既往の部材実験や有限要素法による数値解析では、有開口耐カ壁の崩壊機構や構造性能は、開口の形状や位置の影響を受けることが確認されているが、実務設計に適用可能な評価法の確立には至っていない。%Multi-story structural walls, which are one of the most important seismic components in building structures, often have openings for architectural reasons. Location and size of the openings affect the lateral load carrying capacity and deformation capacity of structural walls. In this study, multi-story wall specimens with openings were modeled as a moment resisting frame, which consists of columns with wing wall, beams with hanging wall and walls with column at one side end, and pushover analysis of them was carried out for simulating their failure mechanism and structural performance. In addition, evaluation method of the amount of opening reinforcement for ensuring assumed failure mechanism was also proposed.
