The local buckling strength of stainless steel beam webs subjected to a stress gradient

M.Ing.In this study the results on the local buckling strength of web elements in lipped channel beams are presented. The steels chosen for this study are AISI Type 304, 430 and Type 3CR12 stainless steels. Lipped channels with varying web height-to-thickness ratios were tested in pairs with the lips and flanges facing inward in a four point loading configuration. It was found that the theoretical results is a good representation of the experimental results if the plasticity reduction factor was set equal to 1
