| Abstract: | A simple three-dimensional constitutive relation for concrete is presented in this paper.A program which can analyze nonlinear properties of reinforced concrete structures under three-dimension stress conditions is written and two models of reinforced bar are considered in the program.Compared with two classical examples of concrete structures,the numerical examples illustrate that the load and process of structure failure can be effectively simulated by the present constitutive relation for concrete. |
