일체형 T-stub를 이용한 기둥-보 접합부의 역학적 거동에 관한 실험적 연구

다국어 초록 (Multilingual Abstract)

For steel structures of building, the connect which connects column and beam must have structural rigidity of the movement and the transmission of stress, with showing the resistance force and the ability of deformation by design considered performance for construction work enough. Generally, all of the analysis and design of connect is assumed the rigid style that does not make a rotation occur but delivers the moment at the panel point and the pinned style which breaks out a rotation only. However, actually, the safety of frame and economical design is not applied in movement of realistic buildings, because the movement of column-beam connect slightly have binding force for delivering moment and rotation. Accordingly, this research will give the basic materials of connect design by reformed T-stub which closes to semi-rigid connection improved turning force. In cases of four models, I had loaded the specimens with giving variables the length of overhang. Through the research, I got some conclusions as follows. 1) The leverage effect of the tension connect did not happen. 2) TL4 specimen which was the longest overhang length had the biggest ultimate strength. 3) The semi-rigid connection of unified T-stub connect showed good restoring force situation for repeated load. 4) It is necessary that we should find a proper measure to take care of slip phenomenon of the connect caused by repeated load.
