Abstract
So far, it has been proven that concrete structures have good resistance against incoming forces, but the rebar inside the concrete may be damaged and fail prematurely due to execution or calculation errors. Therefore, it is necessary to take measures after construction to strengthen concrete buildings. It is customary to increase the capacity and durability of the column by planting composite rebar in concrete (NSM method). Therefore, it is important to investigate the effect of simultaneous reinforcement of composite sheet and rebar and to optimize its installation method on concrete columns. In this research, 12 concrete columns were strengthened by rebars and composite sheets with different numbers and modes of installation, which were analyzed in three separate groups and their results were compared. The initial model was adjusted according to the reference article using the finite element method in Abaqus software. Then this model was reinforced with GFRP rebars by NSM method and enclosure with FRP sheet. In this research, the important parameters of retrofitting such as load capacity and seismic durability, energy consumption rate, ductility ratio, hardness reduction rate, behavior coefficient, failure analysis and economic index were investigated. The results of this research showed that, on average, using the NSM method along with the FRP sheet wrap can increase the seismic durability of the column by 30%. Also, the use of 8 NSM rebars significantly increases the seismic durability of the column, but it will cause the behavior of the column to become brittle and cause unexpected and sudden fractures.
