A master’s thesis was submitted to the College of Engineering – Department of Civil Engineering tagged (Efficiency of reinforced concrete beams strengthened with SIFCON and CFRP) by Essam Youssef Jabbar. It examined the structural behaviour of those beams under the influence of static load, where a laboratory study was conducted, the practical part included casting and testing 14 models. The laboratory results, after a comparison between the reference beams and those reinforced with carbon fiber sheets with a length of 70 cm, indicated that the increase is 7.2% compared to the unreinforced reference beam.
While the beams containing SIFCON with a thickness of 30 mm and with a percentage of steel fibers (2%, 4%, and 6%) showed an increase in the final load by (14.9%, 25.2%, and 32.9%), respectively, all the beams failed to bend. While the beams containing SIFCON with a thickness of 30 mm and a percentage of fiber (2%, 4%, and 6%) and reinforced with carbon fiber sheets with a length of 100 cm showed an increase in the final load by (20.8%, 32.9%, and 38.5%), respectively, compared to the reference beam reinforced with fiber sheets. The carbon fiber was 70 cm long, and the type of failure was dislocation at the ends of the carbon fibers with a layer of SIFCON.
