Abstract: Advanced fiber-reinforced polymer (FRP) composites are being used as mainstream structural materials to build complex infrastructure systems. FRP composites are increasingly being considered as alternative structural materials to traditional construction materials such as timber, concrete, and steel. Such application of FRP composites can be attributed to their high strength-to-weight and stiffness-to-weight ratios, corrosion resistance, higher energy absorption, durability, and competitive life-cycle costs. In this work, detailed experimental investigation has been carried out on different types of glass FRP composite pedestrian bridges with FRP and/or timber deck. Two full-scale, single-span FRP pedestrian bridges with dimensions of 21.3m×2.6m and 21.3m×3m were tested at coupon, component, and system-levels. Coupons and individual component characterization was conducted to determine the stresses, strains, failures, and associated factors of safety. Strains and deflections were measured on various members of the bridges at different locations under the application of loads equivalent to H5 vehicle, 4.8 kPa Uniform Dead Load (UDL), lateral wind load, and equestrian loads. Dynamic excitation tests were conducted on the bridges to establish their natural frequencies in the lateral and longitudinal direction and compared with AASHTO Guide Specifications FRP Pedestrian Bridges standards. The structural response and modifications related to the design and performance of the pedestrian FRP bridge are discussed.
