本研究では梁間方向を含む鉄骨置屋根支承部の応答評価を最終目的とし,まずモルタル厚さ60mmを有するPTFE滑り支承,摩擦ダ ンパー支承,厚さ60mmのゴムシート支承を実際に製作し,動的載荷実験を実施してその履歴特性を確認し,次に得られた復元力特性を用いて同支承を学校体育館規模の支持架構付き円筒ラチスシェルに挿入した解析モデルを構築し,各支承部が支承部応答反力や支承部 応答変形に与える影響を確認しました。摩擦ダンパー支承実験の第二弾です。論文はこちら
Numerous steel roof bearings in RC gymnasia were damaged at the 2011 Tohoku and 2016 Kumamoto Earthquake, mainly due to the out-of-plane response of cantilevered RC walls. Although the authors confirmed the longitudinal response reduction effect of the cantilevered RC walls by friction damper bearings, the transverse response was not examined. In this paper, dynamic loading tests of a sliding bearing with PTFE sheets, a friction damper bearing, and a rubber sheet bearing are conducted. The response of the RC walls in the longitudinal and traverse direction is calculated by numerical simulation using bearing hysteresis loops constituted by test results.
