Abstract
Carbon fiber reinforced polymer (CFRP) reinforcement has been studied as an alternative to steel reinforcement due to steel's high susceptibility to corrosion in bridge girders. The use of deicing salts on roads during extreme cold is the primary cause of the corrosive environment due to salt percolation through cracks. This research manifests the flexural behavior of carbon fiber polymer reinforced beams in prestressed and non-prestressed conditions as well as the variation of the behavior from conventional steel reinforced beams including the design procedure of a prestressed CFRP box section beam through a case study. Unlike steel, CFRP has different stress versus strain relationship - linear without a definite yield point. A review of literature is done regarding the history, properties, applications, and researches in this field. A comparative study is done between the behavior of CFRP reinforced beams using previously tested rectangular and decked bulb T-beams. The study also focuses on the field of application, guidelines, and provisions in different parts of the world, design procedure, characteristics and weaknesses of the material, handling of CFRP in the field, and its design. The application of CFRP as the main reinforcement is scarce because of its brittleness and limited research. However, the strength and lightness make this material ideal for use in the construction industry. It is important that these beams have adequate ductility to prevent sudden failure. Ductility of similar types of beams with conventional and CFRP materials are studied and compared through deformability index. Several methods of calculating ductility are discussed and an ACI method is selected to find the ductility of each beam and a comparative study is done. The behavior of prestressed CFRP tendon is examined when it is used as an alternative to the conventional steel tendon through a case study relating different provisions of code through the design of a prestressed CFRP box section beam over the Ottawa river.
