AB - Stainless steel is an attractive material for exposed structural elements due to its durability and aesthetic appeal. As part of a larger project investigating the enhancement of robustness of steel frames via the use of ductile stainless steel connection components, this study focuses on the structural behavior of stainless steel lap joints under loading rates likely to occur during the progressive collapse of a structure. A total of 21 experimental tests on lap joints, comprising 4 static and 17 at loading speeds ranging between 4 and 11mm/sec, have been conducted and are reported herein, complementing previously reported static tests on similar specimens. The investigated failure modes include net section fracture and bearing failure, whilst the materials considered include $355 carbon steel, EN 1.4307 stainless steel and the novel nickel-free high strength grade EN 1.4678. Auxiliary material coupon test results at various strain rates are also reported to facilitate the discussion of the experimental results. Contrary to carbon steel, where increasing strain rates lead to an enhancement of the ultimate tensile strength, for the stainless steels considered herein a small but consistent reduction in ultimate strength is observed at moderate strain rates (1/s 10/s) followed by an enhancement at high strain rates. This is observed for the experimental tests on the lap joints reported herein. In all cases the ductility of the stainless steel specimens, albeit reduced with increasing strain rates, is significantly higher than that of their carbon steel counterparts.
