Structural behaviour of slip-in gusset plate connection for double lipped channel cold formed steel using partial strength connection

Abstract

Commonly, the cold-formed connection used screwed joint that advantages in simple and fast installation. However, the screw connections should have many problems when it applied for primary structure such as beam and column. To solve this problem, it can be applied the bolted connections using slip in gusset plate as primary structure. The aims of this paper to study the behaviour slip-in gusset plate connection for double lipped channel C20024 using sub-assemblage frame test. The proposed of connections were rectangular gusset plate (RG) and haunched gusset plate (HG). The failure mode, moment resistance, classification connection and discussion will be presented in this paper. The failure mode of bearing bolt CFS was occur for isolated joint test specimens. All of specimens sub-assemblage frame test have similar failure modes where the beam had lateral torsional buckling. The moment resistance of sub-assemblage frame test for RG connection was 13.17 kNm and HG connection was 17.76 kNm. The classification of strength for all sub-assemblage frame test specimens test were classified as partial strength connection.
