Research on Concrete Applications for Sustainable Transportation (RE-CAST) (UTC)
Abstract:

Fabric Reinforced Cementitious Matrix (FRCM) systems have been developed to strengthen or rehabilitate existing concrete and masonry structures subject to damage, steel reinforcement corrosion or requiring resistance capacity improvements due to increased service loads or upgraded code requirements. Bridge decks, girders and pile caps, and parking structures are subject to cyclic loads caused by moving vehicles and, therefore, experience the fatigue phenomenon. Accordingly, this project is aimed at investigating the parameters that most influence the fatigue performance of Carbon- and PBO-FRCM strengthened elements and, in particular, flexure-deficient reinforced concrete (RC) beams. The proposed work includes material characterization of both PBO-FRCM and Carbon-FRCM systems and experimental testing of RC beams strengthened with FRCM subject to static and fatigue loading. As an outcome, the stress ratio vs. number of cycles (S-N curve) that specimens endured before failure was established for each strengthening system.
