Obtención del módulo de elasticidad y coeficiente del Poisson del Hormigón mediante compresión simple para la provincia de Loja

Abstract

The modulus of elasticity is important from a design point of view in reinforced and prestressed concrete, since it controls the behavior of concrete as well as the compressive strength, particularly in structural elements subject to bending. Since the compressive strength can be easily determined without complex elements, a great effort has been applied to find an empirical relationship between the compressive strength and modulus of elasticity. In the literature there are many equations applicable to concrete of different types; However we have left by the American Concrete Institute (ACI). Also the Poisson coefficient is an important factor within the structural field, since it intervenes in the calculation of the shear modulus and this in turn in the calculation of the stiffness matrix of structural elements.
