The main purpose of the research project reported herein was to determine the stress-strain behavior, ultimate strength, and failure mechanism of high-strength concrete subjected to biaxial compression. Model concrete plate specimens, composed of nine aggregate discs embedded in a mortar matrix, were used. Three different strength and elastic properties were used in order to determine the effects of material properties on the behavior of high-strength concrete subjected to biaxial compression. The plate specimens were tested using four biaxial stress ratios 0 uniaxial, 02, 0.5, and 1.0. Deformations in both the major and minor principal directions were measured using Direct Current Differential Transducers. Stress-Strain characteristics, discontinuity, ultimate strength and failure modes in biaxial compression as a function of materials properties are discussed.
