Seismic Rehabilitation of Reinforced Concrete Bridge Substructure Using Fibre-Reinforced Polymer Composites (Poster)

Many bridge structures throughout the world contain seismic strength deficiencies that can lead to catastrophic failures when subjected to earthquake loads. Traditional rehabilitative methods can be costly and have a significant impact on the weight and aesthetics of the structure. A recent bridge retrofit implemented the use low-profile fibre-reinforced polymer (FRP) composites on the Mission Bridge in British Columbia. Over the last twenty-five years, FRP composite strengthening systems have developed into reliable alternatives to traditional structural repair materials and seismic retrofit methods for reinforced concrete bridge structures. With the low-impact, cost-effectiveness and ease of installation of these materials, the number of projects with FRP's being specified for rehabilitation, strengthening, and protection of structural elements is continually growing. The Mission Bridge seismic strengthening project provides one example of effectively utilizing fibre-reinforced composite systems on bridge structures. In this case, high seismic demands were able to be designed for and the FRP system was installed in a costeffective and rapid rehabilitation manor. When designed, detailed and installed correctly, FRP materials can provide a long lasting, effective strengthening solution with minimal impact on the existing structure and its surroundings.
