摘要

•Confined column having either large dilation or large confining pressure fails rapidly.•Stress–strain responses are compared for confined circular and square columns.•Significant dilation activates confinement at low stress yielding higher stiffness.•Consequential drop in final stiffness is remarkably observed in such columns.•Uniformity in the confining pressure distribution restrains such a phenomenon.
