This paper describes a test program on cold-formed stainless steel tubular T-joints fabricated from square and rectangular hollow sections brace and chord members. The normal strength austenitic stainless steel of type AISI 304 specimens were tested. The tests were performed by supporting the chord member of the specimen along its entire length with the pure concentrated force applied to the brace member. The ratio of brace width to chord width (j8) of the specimens varied from 0.5 to 1.0 so that failure modes of chord face failure and chord side wall failure were observed. The test results were compared with the design procedures in the Australian/New Zealand Standard for stainless steel structures, CI DECT and Eurocode design rules for carbon steel structures. Generally, it is shown that the design strengths predicted by the current design specifications are conservative for the test specimens calculated using the 0.1%, 0.2%, 0.5% and 1.0% proof stresses as the yield stresses. The 0.2% proof stress is comparatively more reasonable to predict the design strengths of stainless steel tubular T-joints for both ultimate limit state and serviceability limit state. In this study, it is shown that the ultimate limit state controls rather than the serviceability limit state for most of the test specimens.
