SHN강재를 적용한 대형보의 내진접합상세 개발 및 성능평가

초록

ABSTRACT：This study evaluates structural performance of beam-to-connections for large beams of over 750mm and less than 900mm in accordance with loading procedure of FEMA 350 presented. And, seismic connection details for beam-to-connections made from SHN steel were developed by this study. From the series of experiments, the connections are recognized as Intermediate Moment Frames(IMF). If horizontal reinforcing plates are installed in large beam, those can induce ductile fracture, and seismic resistance of the large beam will improve. So the improvement of installation and experimental methods will be considered to be recognized as Special Moment Frame(SMF).
