CFT 기둥의 더블 웹 앵글 볼트접합의 이력거동

초록

This paper presents results from a systematic finite element study on the structural behaviors of bolted double-web angle connections to CFT column subjected to cyclic loading. The three-dimensional nonlinear finite element models are constructed to investigate the rotational stiffness, internal capacity, and failure modes of the partially restrained composite CFT connections. A wide scope of additional structural behaviors explain the different influences of the double web angle connections parameters, such as mechanical and material parameters, such as the diameter-to-tube wall thickness ratio, aspect and thickness ratios of stiffeners, the moment-to-shear ratio, the yield strength ratio of high strength steel, and the compressive column stress effects.
