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

摘要

The report describes welded connection tests which were performed on C350L0 Rectangular Hollow Sections (RHS). The thickness of the RHS sections varied from 1.6 mm to 3.0 mm. Both butt welds and transverse fillet welds were tested, where the tension load was perpendicular to the direction of the weld. The test results are compared with existing Australian, American, Canadian, and European design formulae. Proposed design formulae are given. The reliability analysis method is used to calibrate the existing and proposed design formulae.
