Reliability Assessment of Canadian Design Provisions for Single-Sided Fillet Welds
An experimental program was conducted at Dalhousie University to test single-sided fillet welds in cruciform connections subjected to branch axial tension. The connections varied the fillet weld size and branch-plate thickness to investigate the effects of these parameters on weld strength. Using the ultimate loads at weld rupture, an approximate first-order reliability analysis was performed, and the inherent safety index (β+) of current (CSA S16:19) design provisions for single-sided fillet welds was determined. Results are compared to those from previous finite-element analyses on single-sided fillet welds in hollow structural section connections. The current provisions, which prohibit the use of the directional strength-increase factor for single-sided fillet welds, are shown to meet the target safety index of β+ = 4.0 across all tests.
