The use of fibre reinforced polymers (FRP) for increasing the strength of RC structures became a usual method. FRP presents easy application and demands low space and provide significant strength increase. Usually, the decision for FRP use is made in terms of applied loads and deflections. However, such quantities can vary significantly depending on the characteristics of the structural element e.g. span, effective depth and concrete resistance. Therefore, this paper aims to present an alternative control variable to analyse the behaviour of RC beams repaired with glass fibre reinforced polymer (GFRP), called damage. Such damage variable accounts for concrete cracking and it was experimentally measured before and after the application of GFRP. Note that the application of GFRP increased the ultimate load for all repaired beams. The damage values of such beams also increased when collapse was reached. Furthermore, it was observed that the collapse mechanism shifted to shear and did not occurred the failure of the GFRP.

This paper presents a new method for deck-to-girder connections of glass fibre reinforced polymer (GFRP) bridge decks. To design the connection system, a GFRP deck in a rectangular cross-sectional shape is considered. The size of the shear bolts, bolt location, bolt spacing, and the size and type of stiffening plate are the variables considered in the design. The behavior of the proposed deck-to-girder connection system was analysed using commercial finite element analysis software. The failure of the connection system was checked by the Tsai–Hill criterion. Effective deck-to-girder connection details for GFRP bridge decks are identified and presented based on the results of the analysis.Key words: bridge decks, glass fibres, bolted connections, pultrusion.
