Resumen
En el presente trabajo se lleva a cabo el estudio del comportamiento de una unión base de columna rígida. Para ello se empleará software Abaqus/Cae (versión 6.14) el cual tiene implementado el método de los elementos finitos (MEF). Además se realiza una revisión bibliográfica de los diferentes estudios teóricos experimentales y numéricos realizados tanto nacional como internacional en esta materia. Que son el punto de partida para la definición de: el tipo de modelo constitutivo del material a utilizar, los diferentes tipos de contacto entre las partes del modelo, y el tipo de elemento finito entre otros.
En la confección del espécimen virtual, se plantean bases metodológicas para la modelación numérica de este tipo de unión, ejemplificándose: la modelación de la geometría, de las cargas, de las condiciones de apoyo y las de borde o frontera de los modelos. Una vez ya obtenidos los resultado de los modelos es posible comprender entonces el comportamiento tenso-deformacional que ocurren en el interior de las partes componentes de los especímenes con la ayuda de los gráfico policromáticos que el software facilita. También se pudo conocer la influencia de las distintas variables que intervienen en la modelación (excentricidad de la carga, espesor de la placa y la resistencia del hormigón).
In the present work the behavior of a rigid column base union is studied. For this purpose Abaqus / Cae (version 6.14) software will be used, which has the finite element method (MEF). In addition, a bibliographic review of the different experimental and numerical studies carried out both nationally and internationally in this field is carried out. Which are the starting point for the definition of: the type of constitutive model of the material to be used, the different types of contact between the parts of the model, and the type of finite element among others. In the creation of the virtual specimen, methodological bases are proposed for the numerical modeling of this type of union, exemplifying: the modeling of the geometry, the loads, the conditions of support and the boundaries of the models. Once the results of the models have been obtained, it is possible to understand the tenso-deformational behavior occurring inside the component parts of the specimens with the help of the polychromatic graphs facilitated by software. It was also possible to know the influence of the different variables that intervene in the modeling (load eccentricity, plate thickness and concrete strength).
