Experimental research has shown that one of the key factors affecting the behaviour of reinforced concrete structures strengthened with externally-bonded fibre-reinforced polymer (FRP) is the bonding behaviour between concrete and FRP laminates. As a complement to experimentation, this paper proposed the use of serial/parallel mixing theory in numerical simulation, which is a tool for studying the behaviour of the concrete-FRP epoxy interface. An example is presented which analyses beam test simulation results and compares them with the experimental results.
Diversos estudios experimentales han mostrado que uno de los factores que afectan el comportamiento de estructuras de concreto externamente reforzadas con Fiberglass Reinforced Plastic (FRP, por sus siglas en inglés) es la adherencia entre el concreto y el FRP. En complemento a la experimentación, en este artículo se propone el uso de la teoría de mezclas serie/paralelo en la simulación numérica como una herramienta para estudiar el comportamiento de la interfaz concreto-epoxi-FRP. Además, se presenta un ejemplo en el que se analizan los resultados de la simulación de un ensayo de adherencia por flexión y se contrastan con los obtenidos experimentalmente.
