La simulación numérica del comportamiento de los materiales compuestos es un campo en desarrollo cuya aplicación a estructuras ha experimentado avances importantes que han conducido a mejoras en el refuerzo de las mismas. En relación con este tema, el artículo parte de la teoría de de mezclas serie/paralelo que permite deducir el comportamiento de los compuestos a partir de las ecuaciones constitutivas de los materiales componentes. Con el fin de destacar las ventajas que tiene esta herramienta en el análisis y el diseño de estructuras reparadas o rehabilitadas con polímeros reforzados con fibras largas (FRP), en el artículo se realizan análisis numéricos mediante modelos de elementos finitos de un conjunto de pórticos con distintas configuraciones de refuerzo. Los resultados obtenidos muestran que el uso de esta teoría contribuye a mejorar el análisis y el diseño de las estructuras reforzadas con FRP.

The advantages provided by this formulation to simulate concrete structures reinforced or retrofitted with Fiber Reinforced Polymers (FRP) will be shown from the analysis of several finite element models, consisting of a set of concrete frames with different strengthening configurations.

Abstract

The numerical simulation of composite materials is a field under continuous development. Its application to structural design has shown important improvements, leading to a better simulation of strengthened structures. This paper uses the serial/parallel mixing theory to predict the mechanical behavior of composites. This theory uses the constitutive equations of the component materials to obtain the composite performance. The advantages provided by this formulation to simulate concrete structures reinforced or retrofitted with Fiber Reinforced Polymers (FRP) will be shown from the analysis of several finite element models, consisting of a set of concrete frames with different strengthening configurations. The results obtained will show that the use of this theory to simulate FRP reinforced structures improves their analysis and design.
