| 要旨 | In this paper, a unified plastic model for concrete, in which only one criterion is considered to describe the behavior of concrete under different stress states, is used. This model can treat a major nonlinear phenomenon of concrete such as cracking shear transfer degradation, tension stiffening and compressive strength reduction. Moreover, localization signal is used to define shear band direction as well as mode of failure when the element passes peak point of loading. This phenomenon occurs when the material acoustic tensor A(n) looses its positive definiteness (det.A(n)=0). The method has been evaluated by experimental results of Vecchio and Collins. |
