Axial and Flexural Performance of Adhesive Connection on Cold-Formed Steel Structures

Siti Nur Rahmah Anwar, Priyo Suprobo, Endah Wahyuni



In this paper, a research of new connection method on the
cold-formed steel in civil engineering structures is presented. The study
focuses on the axial and flexural performance on cold-formed steel structures.
A cold-formed steel with screw, adhesive and combination connections that have
been loaded in tension and flexure until rupture. A comparison strength in
tensile and flexure between the joint types and screw joint on cold-formed
steel were investigated. The use of adhesive as the joint (connection) be able
to increase the structure capacity significantly. Combination joint between
screw and adhesive on cold-formed steel structure could prevent premature
collapse of the structure. Adhesive in the combination joints also could
minimize the bearing failure of screw joint. It was caused by the rigidity
cold-formed steel structure that has increased throughout the adhesive joint.
The effect of local buckling could be minimized with increasing structural
rigidity. The adhesively
bonded joint strength is based on the type of adhesive. The joint failure was
began at the end of an adhesively bonded area then it propagated to the middle
until it was fully degraded.
