반복하중을 받는 고강도 원형강관 T형 접합의 면내 휨모멘트 평가 / Evaluation of the In-plane Bending Moment for T-Joints in the Circular Hollow Section of New High Strength Steel Subjected to Cyclic Loading

초록

This paper presents results from a systematic finite element study on the in-plane bending moment for T-joints using high strength (i.e., yield strength of 600 MPa) circular hollow section under cyclic loading. The three-dimensional nonlinear finiteelement models are constructed to investigate the strength, rotational stiffness characteristics, and failure modes of the welded joints. Awide scope of additional structural behaviors explain the influence of the joint geometrical parameters and compressive chordstress effects on the ultimate joint strength.
