PLASTIC STABILITY OF PIPES AND TEES EXPOSED TO EXTERNAL COUPLES

This is the fourth in a series of WRC Bulletins on plastic collapse tests of cylindrical shells with single-nozzle attachments; the testing described in this series was initiated by the Subcommittee on Reinforced Openings and External Loadings about nine years ago. The previous bulletins of the series are 200, 219, and 230. Experimental results on plastic deformation of four pipes exposed to out-of-plane couples at the branch are given. The test data indicate that both pipes and tees buckle plastically under these loading conditions and that in case of tees exposed to out-of-plane couples the carrying capacity is determined by plastic buckling and not by plastic limit loads for certain geometries.
