Flexural Strengthening of Reinforced Concrete Beams with Textile Reinforced Concrete (TRC)

摘要

Carbon-epoxy composite materials are of considerable interest for reinforcement, but they need to be improved and have constraints, particularly in terms of cost and criteria of sustainable development. Such alternatives as textile reinforced concrete (TRC) should be seriously considered as substitutes for traditional composite materials. It is in this background that this study aims to explore the feasibility and assess the mechanical performance of reinforced beams in bending. This work focuses on the mechanical feasibility of such solutions by comparing them with traditional solutions such as CFRP and NSM (deformation rate rein-forcement, cracking density, ultimate load, degradation level... etc.) on the basis of an experimental campaign based on 5 beams tested under four point bending. Finally we will try to adapt, supplemented where appropri-ate, CFRP predictive models in the case of the TRC and assess their degree of relevance.
