Abstract

Cold-formed research that has been studied, which still focused on the capacity of beam and column components. Nonetheless, there is still a lack of data and knowledge on the composite construction behavior, and the performance of CFS Composite beam advantages such as strength and cheapness have led to the dominance of composite beam in the commercial building. The purpose of this study is to investigate the failure modes that occur and present the results of the strength and stiffness of the gusset plate connection of the composite structure. This study uses one type of connection made in the form of cantilever beams whose floor plates use concrete cast with metal decking. The shear connector used uses M12 grade 8.8 bolts with the same tensile stress as the other bolt connections. Beams and columns use cold-formed steel with a thickness of 2.4 mm with a DLC200 size for the beam and a DLC300 size for the columns. The connection uses a hot-rolled steel type gusset plate with a thickness of 6 mm. This failure mode can be indicated that there is an influence of the sliding bolt resistance and bolt support on the joint resistance. Deformation also occurs on a concrete plate that occurs at a distance of 100 mm from the face of the column flange The recording results show the ultimate load achieved is 31.6 kN with 62.26 mm deflection. The ultimate moment occurs is 31.6 kNm with a rotation of 0.038 rad, and the stiffness experiment is 730 kNm/rad. The ratio of the moment experimental with analytical calculations showing a good agreement of 1.41. The ratio between other study has 0.50 ratio of moment resistance and 0.46 for stiffness
