BEHAVIOR OF ROLLED SECTION WEB UNDER ECCENTRIC EDGE COMPRESSIVE LOADS

The results of 22 tests conducted to study the effect of the eccentricity on the ultimate cpacity of rolled sections are presented. Eccenntricity ranged from 0 to 0.5 inch. Loads were applied through a thick patch plate or a cylindrical bar. The bar failure mode differed significantly from the common web crippling which occurred when the patch plate was used. A linear finite element model is presented. The results of the analysis is compared with the test results obtained at the initial stages of loading, before large deflections or local yielding occur. It was found that, if the load is applied through a rigid patch plate with an eccentricity with respect to the plane of the web and if part of the patch plate is over the web, the effect of the eccentricity is negligible. These and other findings are discussed.
