Title:†CUTINSHEAR - Performance assessment of an innovative structural FRP strengthening technique using an integrated system based on optical fibre sensors

Reference:†POCTI/ECM/59033/2004

Description:†Develop a novel shear strengthening technique using laminates of CFRP, which, in comparison to the existent CFRP-based shear strengthening techniques, is simpler and faster to apply and is more efficacy in terms of provide higher increase of beam load carrying capacity and deflection at beam ultimate load.† Develop equipment for saw-cutting the slits where the CFRP laminates will be bonded by epoxy adhesive. This equipment should allow cutting slits of regulated width and deepness, and desired longitude. Develop a unit control and acquisition system for measuring the strains in the CFRP laminates using optical fibers. These sensors will introduce marginal interference in the CFRP-concrete bond conditions. This device will be implemented into a servo-loop system to assure stable tests, controlling the test by the signal registered in the optical fiber sensors. Develop design guidelines for this shear strengthening technique.

Date:†March 2005 to March 2007
