本研究では，摩擦ダンパーを含む滑り支承で鉄骨造屋根に接続されるRC片持架構の構面外応答制御設計法を提案しました。本研究は置屋根体育館の耐震性能に関する研究シリーズの一つで、防災科研，東工大，工学院大学，日鉄エンジニアリングとの共同で行った振動台実験を引用しています。卒業論文の提案から設計法の完成まで8年もかかるとは思っていませんでした。この設計法の提案は先輩、後輩、教え子など多くの方々との長年の試行錯誤の末に到達した成果です。関係する皆様に深くお礼申し上げます。論文はこちら
In steel roof gymnasiums with RC substructures, out-of-plane response of cantilevered RC walls are predominant during seismic responses, which triggers sequential damages of structural or non-structural components. Detailed regulations have been not included in the current Japanese building code yet even though Gymnasium is used as a shelter in disaster. In this paper, a design procedure for out-of-plane response control of a cantilevered RC wall connected by roller supports to metal spatial roof was proposed. While many researchers proposed response evaluation methods for cantilevered RC walls, those methods are too complicated to be implemented in the actual design process. Therefore, the proposed design procedure is carefully formulated based on Japanese structural engineer’s practice. The design equation is derived from both equivalent linear approach simulating damping effect and continuum mechanics where a cantilevered RC wall is modeled as single beam or single plate.
