Abstract: Based on the experiment, this paper investigated concrete strength under biaxial compressive stresses, and some existing failure criteria of concrete were reviewed and compared with each other by calculating. Comparison of the test results with those of other researchers was made. From the viewpoint of practical use in engineering, a proposed formula for predicting concrete strength under biaxial compressive stresses was presented.

Key words: concrete, biaxial stress, failure, strength
