Title of the articleBEHAVIOR OF SLABS REINFORCED USING SQUARE GFRP REBARS
Abstract.Corrosion of steel bars is a common problem encountered in steel reinforced concrete structures. The repair of steel corrosion costs a lot of money and time. The use of fiber-reinforced polymers (FRP) reinforcing bars instead of steel rebars is a reasonable solution of the corrosion problem. In this paper, a study was made to enhance the behavior of slab specimens reinforced using GFRP rebars. The parameters included in this study were, the geometry of bar cross-section, the characteristic strength of concrete, reinforcement percentage, and the percentage of polypropylene fibers in the concrete mixtures. Test specimens were nine, one-way, slabs. The study revealed that reinforcing one-way slabs in this research using GFRP rebars, square in croess-section, is effective in enhancing slabs` failure mode, cracking and ultimate loads, and deflections than using GFRP rebars circular in cross-section. Test results were analyzed and compared together and the corresponding conclusions and recommendations regarding the behavior and design of such slabs were drawn.
Keywords.Square rebars, GFRP rebars, Polypropylene fibers, slabs.
