Abstract

In this paper, a research of new connection method on thecold-formed steel in civil engineering structures is presented. The studyfocuses on the axial and flexural performance on cold-formed steel structures.A cold-formed steel with screw, adhesive and combination connections that havebeen loaded in tension and flexure until rupture. A comparison strength intensile and flexure between the joint types and screw joint on cold-formedsteel were investigated. The use of adhesive as the joint (connection) be ableto increase the structure capacity significantly. Combination joint betweenscrew and adhesive on cold-formed steel structure could prevent prematurecollapse of the structure. Adhesive in the combination joints also couldminimize the bearing failure of screw joint. It was caused by the rigiditycold-formed steel structure that has increased throughout the adhesive joint.The effect of local buckling could be minimized with increasing structuralrigidity. The adhesivelybonded joint strength is based on the type of adhesive. The joint failure wasbegan at the end of an adhesively bonded area then it propagated to the middle
