[PERSON] et al. tested eight short columns subjected to axial load to study the shear failure of RC columns. Seven samples were partially or fully- wrapped by CFRP or GFRP. For those continuous wrapped columns, the increase in both resistance and ductility, have been reported [29]. [PERSON] et al. [30] performed a study to investigate the behavior of reinforced concrete columns confined with carbon and glass fiber reinforced polymer sheets. Their results showed that both the compressive strength and its corresponding strain at failure experience a significant increase when the CFRP or GFRP is wrapped. They concluded that the concrete compressive strengths and strains at failure increased significantly when the column is confined with GFRP and CFRP straps [30]. In a review paper presented by [PERSON] et al. [31], it was shown that among all jacketing techniques, FRP confinement is an effective method when it comes to integrity. There were also some studies carried out by [PERSON] and [PERSON] [25], [PERSON] et al. [32], [PERSON] et al. [33], and [PERSON] et al. [34]. The developed techniques are studied to repair the underwater RC structures that are subjected to corrosion. In these techniques both CFRP and GFRP sheets have been considered to retrofit the piles. These studies recommended strategies to optimize the cost of repairs. Furthermore, the compressive strength of the reinforced concrete, ductility, and energy dissipation can significantly be improved by wrapping with CFRP sheets [35]. There are only a few studies that have concentrated on the flexural behavior of RC beams where the GFRP bars are embedded in the beam, such as the study conducted by [PERSON] et al. [36]. They investigated the buckling failure of the GFRP-reinforced concrete square columns. Their results indicated that the failure of this type of beam is controlled by the spacing between stirrups. In their research, GFRP longitudinal reinforcement and confined GFRP stirrups were considered as the only reinforcement bars. However, due to difficulties in having the GFRP bent by the factories, it might not be feasible or economic to be considered at the industrial scale. FRP bars have been used as a substitute rebars for RC structures since FRP reinforcement bars have noncorrosive and nonconductive properties in comparison to steel reinforcement [37]. Having constructed and immersed in the seawater, steel rebars in RC columns need to be protected against corrosion. In addition, it has been proved that longitudinal FRP bars increase the axial compression performance [38; 39; 40; 41; 42] as well as improve the chemical and physical corrosion [43] because the polymeric materials used in FRP composite have the ability to resist corrosion [44; 45]. Moreover, using FRP rebars materials in RC structures enhances the durability of the concrete and its resistance to the corrosive environment which makes the structure to perform better over a long period of time and reduces maintenance costs in comparison to the steel rebars [46]. Based on the aforementioned discussion, there are many studies that focused on the importance of FRP materials to improve the structural performance. Although many of these prove that FRP sheets and bars pave the way for enhancing structural integrity, none of them evaluated the simultaneous factors of cross-section, reinforcing pattern and its material properties on structural capacities. Moreover, there is no related study to show the optimization aspects of the stated variables. Therefore, this research represents the effect of FRP bar materials on structural performances for various types of cross-sections and height. It also presents a new model development approach to compute the seismic behavior of structural components. The theoretical study of the current research focuses on the effect of stress-strain behavior of different cross-sections of reinforced concrete columns in which the FRP bars are embedded as a reinforcing material in order to improve the axial compression with the novel method presenting in this paper.
