Comportamiento no lineal del concreto y sus aplicaciones en ingeniería

Abstract

Theoretical considerations: The analytical constitutive relation of concrete under general three-dimensional stress state has been proposed. In the formulation, the concrete is assumed to be a continuous, isotropic, and linearly elastic-plastic strain hardening-fracture material. The elastic-plastic stress-strain incremental relationships, based on the initial discintinuous surface, loading surfaces, and failure surface of concrete are derived using the classical theory of plasticity.
