| Abstract | ||
| One of the new technologies used in increasing the bearing capacity of concrete structures is the replacing of standard (normal) reinforcement by bars made of carbon fibers making use of its properties, which gives an advantage by being antirust. In this research, an experimental study of the behavior of concrete beams reinforced with strips of carbon fibers, (one or two layers), in the tension zone of the beams, with a variable width is performed to study the behavior of the beams from the point of view of their flexural capacity, failure mode, and the effect of the friction between the concrete and the fiber strip on load failure. After conducting the tests, the results revealed that an effective contribution and an obvious role of carbon strips fiber in improving the members bearing capacity and the overall behavior, also increasing the stiffness and ductility at different rates depending on the bond stress and number of strips. | ||
