heal.abstract	The incorporation of realistic constitutive laws of the traxial behavior of concrete into finite-element models that developed analysis package to yield close predictions of the response of a wide range of structural concrete forms subject to loading conditions was analyzed. The increase in strength of the compressive zone due to the development of triaxial compressive stress conditions precludes the need for the contribution to shear capacity. These mechanisms could only be mobilized when the shear resistance of the compressive zone is overcome, as the stiffness of cracked concrete below the neutral axis is smaller than that of uncracked concertes in the compressive zone. The code provisions are improved in both cases by revising those deign assumptions that are in conflict with basic mechanics principles and fundamental material properties.	en
