Popis:	Three-dimensional elasto-plastic and continuum fracture model for concrete, which had been originally developed with reference to uniform stress field, is verified on structural member level of non-uniformity. This study adopts idealized square concrete cores purely confined by closed square lateral steel ties. The constitutive model is examined in view of confining stress induced from lateral steel to core concrete and enhanced strength and ductility of core concrete at the axial capacity of columns. The verified applicable range of the constitutive model is clarified under practical stress conditions and paths arising in RC column members. The effect of loading rate on the plasticity evolution is also discussed.
