Comportamiento de la conexión pilote-losa en hormigón estructural

Abstract

A brief theoretical description of the criteria proposed by several authors and considered in routines using the OpenSEES program to represent the nonlinear behavior under monotonic and cyclic concrete and steel reinforcement loads is presented. The pile-slab connection basic model proposed in this thesis to describe the components independently: bending, adherence and shear is developed. The criterion used for determining the properties of the materials to be used in the body of the pile, which corresponds to the contribution of bending is presented, additionally the adherence contribution model proposed by Oehlers et al. (2008) and Haskett et al. (2009) is detailed, finally also Elwood et al. (2004) model is included, to consider the shear component in pile-slab connection. The optimization and validation of the basic model is done by experimental results obtained by Jellin (2008). The optimization is performed using different type of concrete materials presented in the OpenSEES library, and validation checks by comparing the experimental results with the analytical results obtained with the basic model.
