چکیده مقاله:
In this research, four types of concrete moment frames reinforced with fiber reinforced polymer were designed and then analyzed to evaluate the behavior of moment frames. Firstly, a computer code was written to calculate the amount of fiber reinforced polymer in beams then to evaluate the actual behavior of moment frames, all of the beams and columns sections were analyzed through XTRACT software which is in the base of moment curvature. To examine the performance of moment frame, a nonlinear static analysis was considered and all of the sections were defined as confined section to provide enough ductility. Also, to show the exact behavior of moment frame, all of the plastic hinges in the beams were analyzed in the base of section’s moment curvature and all of the columns plastic hinges were analyzed both through their moment curvature and their PMM interaction curves. At the end, it can be concluded that moment frame reinforced with GFRP and CFRP provide higher bearing capacity but less ductility that is detrimental for seismic zone.
