    The aim of this dissertation is to investigate into whether or not composite and fibre reinforcement methods are suitable restoration solutions for the repairs required on South Parade Pier which has suffered wear since its reconstruction in 1908.
    The Pier is a Grade 2 listed building meaning that no repairs to ‘the pier, structural or otherwise, which could alter its appearance or would damage the heritage of the Listed Structure can be made.’ This puts limitations on the reinforcement techniques which can be used on the Pier. Reinforcement techniques which would require section of the pier to be demolished, e.g. reconstruction to create composite decking’ or additional supports for example extra beams will not be verified by Portsmouth City Council. This is why reinforcement techniques such as carbon fibre wrapping, CFRP plates and epoxy injections are suitable to the repairs which are needed on South Parade Pier.
    Fibre and composite reinforcement methods are becoming ever more popular in the construction industry due to the enhancements they can give to existing structural elements. The tensile strength of CFRP sheet is 3350MPa (Teng, 2001, page 714) which far exceeds that of steel bar. The Elastic modulus of the CFRP is also far higher than that of concrete meaning that if used to reinforce the decking it will take much more tensile stress until failure than the concrete alone.
    The findings of this dissertation show that fibre and composite reinforcement techniques can be used to restore South Parade Pier as an alternative to traditional reinforcement methods in turn saving the costs of replacing existing elements whilst enhancing their structural properties.
