The present paper examines the local failures of unreinforced RHS T-joints when these are subjected to bending moment. The moment joints of rectangular hollow sections (RHS) often comes out in frame-works of multi-leveled rack systems, aboutments of pipe lines and brackets of sub-structures as well as in Vierendeel trusses. In unreinforced RHS T-joints, subjected to, bending moment, various failure modes occur depending on the combination of chord and branch sizes. Since all of. these failures are due to the out-of-plane deformation of chord, they are collectively called local failures. The term local failure implies all premature failure modes such as flexural failure of chord flange plates, web crippling in chords, local buckling of branch and fracture in welds before developing full plastic moment of branch. In this paper, an extensive parametrically programmed study on test specimens was carried out to investigate the effect of the member sizes, including the details of weld, on the local failure.
