STEEL PIPE WRINKLING DUE TO LONGITUDINAL PERMANENT GROUND DEFORMATION

The authors consider the behavior and design of a straight buried steel pipe subject to permanent ground deformation (PGD) where the movement is parallel to the pipe axis. The PGD zone is characterized by the amount of movement, M, and the length or spatial extent, L, of the zone. Steel pipe has the ability to deform in tension well beyond the effective yield strain; therefore, wrinkling of the pipe wall in compression is the failure mode of interest. Critical values for M and L, which result in wrinkling of the pipe wall in compression, are determined for five different pipe materials and various burial conditions. The authors conclude that the behavior and onset of wrinkling are greatly influenced by the length of the PGD zone. A design example demonstrates the utility of this information.
