강구조 인장접합부의 블록전단 파단에 관한 실험적 연구 : T형강 플렌지의 블록전단을 중심으로 Focused on the Block Shear of T-Beam Flange = An Experimental Study on the Block Shear Rupture of Tension Joints in Steel Structure

다국어 초록 (Multilingual Abstract)

This paper presents an experimental study on the propriety of block shear design code, according to limited state design criteria of steel structures recently established in Korea, by testing the joint of T-Beam Flange tension members. The methods of this study were to compare with other study results on block shear rupture mode and ultimate capacity, and to evaluate the propriety of the criteria design code. The result shows that tension yield shear ruptures and shear yield tension ruptures happened at the joint, and the experimental rupture load was 16% higher than the capacity entered in the criteria design code. Therefore, we conclude that it is necessary to revaluate the block shear design code presented by many studies on the limited state design criteria of steel structures and to more study effect of the shear lag in this field.
