Abstract

Cold rolled steel (cold formed steel) is very often used in the field of construction in today's era.However, in its use there are several drawbacks in the use of cold-formed steel, including a thin profileand problematic joints. Especially in the cantilever structure, it is necessary to analyze because themaximum deflection that occurs in the cantilever structure has a greater value than the simple supportedbeam structure. This study aims to study the effect of load on deflection in each type of cold rolled steelbeam-column connection. The results of this study were obtained for the average maximum load that canbe resisted at the screw connection variation is 1.26 kN, the screw-gusset plate connection is 1.43 kN, thescrew-angle cleats connection is 1.92 kN, and at the screw-plate gusset-angle cleats connection is 1.60 kNand for the average value of the deflection that occurs at the maximum load on the screw connection is28.67 mm, at the screw-plate gusset connection is 58.99 mm, the deflection at the screw-angle cleatsconnection is 22.44 mm, and the deflection at the screw-plate gusset-angle cleats connection is 49.67 mm.From these data, it was found that the experimental load-deflection value relationship did not reach theanalytical load-deflection value. At the screw connection the damage that occurs is a tear in theconnection plate (tear out), at the gusset plate connection the damage that occurs is the collapse of thegusset plate, at the screw-angle cleats connection the damage that occurs is 2, where the damage startswith a tear in the connection plate ( tear out) and followed by damage to the screw that was damaged pullout (pull out)
