【Abstract】 This paper introduces several common mathematic representations of elastoplastic constitutive relations of concrete. Utilizing the constitutive relations of elasticity and elastic-plasticity of concrete the numerical analysis is made on reinforced concrete members under axially loaded compression. The influences of the plastic properties of concrete on members are summarized.更多还原
