Abstract

Over the years, the failure envelope of plain concrete has been studied and constructed by various researchers. Since concrete is a non-homogeneous material, its behavior under bi-axial stresses is not as straight forward as steel. Also, the assumption that concrete exhibits an isotropic behavior under loading is not completely true since the failure mode due to tension and compression differs significantly. This research work looked into the correctness of the two most known failure criteria; the Mӧhr-Coulomb (MC) and the Kupfer-Hilsdorf-Rusch (KHR) envelope. In reaching the goal, a Finite Element Model (FEM) was constructed, and a plain concrete beam subjected to flexure was run through the program for a range of concrete compressions strengths. To validate the FEM program, the resulting load-displacement curves were calibrated to experimentally tested specimens. The load-displacement response and the stress-strain behavior at the beam’s center-line up till failure, was recorded for analyze purposes. This research work was conducted at the Structural and Material Laboratory, Diponegoro University in Semarang, Indonesia.
