Abstract
The objective of this paper is to study the static and fatigue performances of concrete beams strengthened with carbon fiber sheets bonded by inorganic resin matrix. Steel concrete reinforced beams were strengthened with 2, 3, 4 and 5 layers of carbon fiber sheets for static study and 3 layers of carbon fiber sheets for fatigue study. Both static and fatigue studies, strength, stiffness, ductility, failure mode and cracking patterns of strengthened beams were investigated. Results showed that the inorganic matrix system is an effective way in increasing strength and stiffness of reinforced concrete beams. Both load capacity and number of fatigue cycles of RC beams were significantly increased with carbon fiber sheets. Fatigue cracks were developed during the first few cycles. The study showed that strengthening RC beams with carbon fiber bonded with inorganic matrix improves both static and fatigue performances.
