ABSTRACT
This paper describes welded connection tests which were performed on C350L0 Square Hollow Sections (SHS) and Rectangular Hollow Sections (RHS). The thickness of the RHS sections varied from 1.6 mm to 3.0 mm. Butt welds, transverse fillet welds and longitudinal fillet welds were tested. The test results are compared with existing American, Australian, Canadian and European design formulae. Proposed design formulae are given. The reliability analysis method is used to calibrate the existing and proposed design formulae.
