Application study of carbon fiber-reinforced polymer material for strengthening reinforced concrete structures

Abstract

Carbon fiber-reinforced polymer (CFRP) is a new material in the field of construction. This material has many outstanding advantages compared to conventional construction materials, such as: very lightweight, extremely high strength, resulting in high reinforcement efficiency; easy and fast installation; no need for drilling the structure; especially its compact size, which ensures it does not alter the original architectural dimensions of the structure. CFRP has been applied in the construction industry in advanced countries since the 1980s, but it is still relatively new in Vietnam. This article presents the technical characteristics, construction process, reinforcement design principles, and then applies them to design reinforcement for bending and shear capacity in a specific reinforced concrete high-rise building project. Through detailed analysis and evaluation, it can be concluded that CFRP can be effectively applied in construction and is highly suitable for reinforcing concrete structures. This article is expected to be a valuable reference for researchers and engineers interested in applying CFRP materials to reinforce concrete structures.
