Connections are often one of the causes of structural failure. The connection structure using cold-formed steel material has been widely studied using 180°straight rod. This study used type C and 90° upright connection. The test objects were joints in various shapes. This study aimed to determine the tensile strength, length increase, and damage with connection in various shapes. This study consisted of six test object variations; each had three repetitions. The variation consisted of rod built in back-to-back and hollow profiles. The second variation was the connection form, consisting of without lip connection, continuous plate, and elbow plate. The cold-formed steel was formed in an I-shaped letter and pulled using UTM. The obtained results were the greatest tensile strength can be held by the rods which are assembled back to back with L plate connection. Back to back connection of rods affects the tensile strength of CFS rods, even though they have the same cross-sectional area. Connection using L plate produces greater tensile strength and less deformation.
