Tests and Design of Longitudinal Fillet Welds in Thin Cold-Formed RHS Members

摘要

The report describes welded connection tests which were performed on C350L0Square and Rectangular Hollow Sections (SHS and RHS) with a thickness ranging from 1.6 mm to 3.0 mm. Longitudinal fillet welds were tested. The test results are compared with existing Australian, American, Canadian and European design formulae. The effect of the direction of loading, the weld length, the end return welds and the orientation of an RHS section on the weld strength are studied. Proposed design formulae are given. The reliability analysis method is used to calibrate the existing and proposed design formulae.
