| Abstract: | Based on the experiments, the stress-strain response behavior of concrete under monotonic proportional biaxial compressive stresses is investigated with the law of the variation of peak (failure) strain with stress ratio or peak (failure) stress analysed. Formulas for estimating peak strain are proposed. The test results are in fairly close agreement with several constitutive models. From the view-point of practical use in engineering, a simple and convenient formula for predicting relations between stress and strain is presented and its calculating results indicate satisfactory precision. |
