Design Proposal to Avoid Peeling Failure in FRP-Strengthened Reinforced Concrete Beams

Eva Oller Ibars; Diego Cobo del Arco; Antonio Ricardo Marí Bernat

According to the available experimental work, the most common failure in existing structures strengthened by plate bonding is the laminate peeling off. In the last few years, an important effort in the development of mathematical models to avoid premature peeling failures has been made. However, a suitable and reliable design method to predict debonding due to the shear flow between crack discontinuities or at the laminate end is still not available. This paper describes a new design procedure for structures strengthened by plate bonding to avoid peeling failure at any location. After calculating the laminate area required for flexural strengthening, a two-step procedure to prevent peeling failure is proposed. The first step, to avoid peeling failure along the span, is based on a shear-bending interaction diagram associated with the theoretical maximum transferred force between laminate and support along the crack spacing before laminate debonding. This interaction diagram can be obtained through the appl...

Resumen La Instruccion Espanola de Hormigon Estructural EHE-08 fue el resultado de una profunda revision de la anterior Instruccion EHE-98, sobre la que se realizaron numerosas modificaciones orientadas a adaptar la Instruccion al actual marco normativo europeo y al actual estado del conocimiento, promover la mejora de la calidad de las obras sin sobrecostes injustificados y contribuir al desarrollo sostenible. En dicho contexto, se realizo un trabajo orientado a comparar los resultados de aplicar la Instruccion EHE-08 y el Eurocodigo EC-2 al proyecto de diferentes estructuras. Se estudiaron seis tipos estructurales, que se consideran representativos de las obras de hormigon estructural mas frecuentes en Espana y que ademas cubren un amplio espectro de las tecnicas de construccion estructural (hormigon armado y hormigon pretensado con armaduras pretesas y postesas, construccion prefabricada y construccion in situ, estructuras de edificacion y de obra publica).
