Abstract: This report presents an experimental study on stainless steel built-up sections under web crippling failure, End-Two-Flange (ETF) loading condition. Total eleven stainless-steel built-up box section specimens with two different gradings of Austenitic Stainless Steel Grade 304 and Duplex Stainless Steel Grade 2205; two different screw groups of 1-screw group and 2-screw group; and three different thickness ranging 1.0mm and 2.0m for Austenitic Stainless Steel Grade 304 and 1.5mm for Duplex Stainless Steel Grade 2205. The relevant testing machine and specimen setup, test procedures, load-deformation curves, and ultimate loads were reported detailly in this report. Due to the absence of stainless steel built-up box sections under web crippling of ETF loading condition from the existing design guideline and specifications, the obtained test results of the ultimate load, Pu,test and the theoretical ultimate load, PEC3 and PAS/NZS from the three different steel design codes respectively, namely (i) EN 1993-1-3: Eurocode 3: Design of Steel Structures; (ii) AISI S100: North American Specification. for the Design of Cold-Formed. Steel Structural Members; (iii) AS/NZS 4600: Standards Australian/New Zealand. The comparison study shows that PEC3 is slightly more conservative than PAS/NZS where both AISI and AS/NZ design codes give overly unconservative capacity estimations. Hence, further investigations to be provided to improve the quality of design codes.
