Modelos de cálculo del hormigón confinado con FRP. Estudio comparativo

Abstract

Investigación experimental sobre pilares de hormigón reforzados con FRP. El confinamiento con un encamisado de FRP se ha convertido en un método habitual de refuerzo de pilares de hormigón armado en estructuras existentes como puentes o edificios. Numerosos estudios experimentales han demostrado que se trata de un modo eficaz de incrementar considerablemente la resistencia del hormigón. En los últimos años se están proponiendo también diferentes modelos teóricos y se han publicado en diversos países guías y recomendaciones con diversas ecuaciones para el cálculo. En este trabajo se revisan las formulaciones propuestas en las principales recomendaciones publicadas incidiendo en los dos aspectos que se han identificado como claves en el comportamiento del hormigón confinado con FRP: la deformación última efectiva del FRP y la influencia de la forma de la sección del pilar en la eficacia del confinamiento
