Abstract: “The application of cold-formed steel in light steel framing design can serve as an alternative for industrialized building system, by extending steelwork construction into residential housing. There is a lack of in-depth study on the joints behaviour in cold-formed steel frames, particularly the beam-to-column connection. This paper presents isolated joint test on three types of joints using bolts and steel angles, namely web-cleats, top-seat flange-cleats and combined flange-web-cleats connections. Six specimens with different joint configuration and thickness of angle were tested. The experimental setup, procedures and failure modes of the joints are discussed in detail. The comparison revealed that by increasing the thickness of angle from 2 mm to 6 mm, the strength of joint’s moment resistance increased in the range of 1.80 to 2.28. The ratio of difference for rotational stiffness increased in the range of 1.27 to 2.06.”
