低降伏点鋼を用いた非埋め込み型RC・S造複合梁の耐震性能に関する実験的研究

摘要

It was shown that the seismic performance of the hybrid boundary beams was excellent. The proposed hybrid boundary beams was applied to super high-rise reinforcement concrete buildings using core-wall method. The hybrid beams consist of steel damper with low yield point steel and RC beams. The hybrid boundary beams is not embedding the steel part to RC part, therefore, it was effective in reducing damage to the RC beams. Further, the analytical model of the hybrid boundary beams was proposed, and the validity of the analysis model was shown by comparison with an experimental results.%低降伏点鋼を用いたRC・S複合境界梁の構造実験および解析により以下の知見を得た。(1)複合梁の荷重変形関係はエネルギー吸収性能に富み，大変形時にも安定した履歴を有する。(2)埋め込み型のダンパーの場合，埋め込み部のテコ作用によりRC部のひび割れが大きくなりダンパーのエネルギー吸収性能に影響を及ぼす。
