Abstrait:

This paper presents the results obtained from an experimental investigation carried out on full-size reinforced concrete beams, which are strengthened in flexure and flexure/shear using different external reinforcement systems having an inorganic matrix, such as SRG (Steel Reinforced Grout) and PBO (Polyparaphenylene Benzobisoxazole) FRCM (Fiber Reinforced Cementitious Matrix).

In order to study the effect of the external composite reinforcement, variations in the number of applied layers and in the external end arrangements were made. All beams were extensively instrumented and tested under four point bending.

The performance of the strengthened beams, in terms of strength and ductility, was evaluated and compared with the control beam to highlight the main parameters that affect the mode of failure and the global behaviour of the structural elements.
