Typically, the beam-column joints were examined based on gravity loads, which weakened the connections against lateral and seismic loads. Quantitative investigations have examined the behavior of the beam-column joints under lateral and seismic loads and, on the other hand, FRP materials are new materials that are considered in the design of structural members; this requires more investigation and research; accordingly, in this The research investigates the seismic behavior of concrete beam-column joints using GFRP meshes. In this research, ABAQUS has been used to analyze and test the samples.In this research, the behavior and performance analysis of the internal and external beam-columns connection of reinforced concrete with GFRP reinforcements under the influence of different axial loads and static and cyclic lateral loads are investigated. In this research, a reference connection using steel reinforced concrete was used to obtain the results to compare the effect of GFRP rebars. Also, to investigate the effect of external reinforcement on internal and external connection, steel reinforcement, concrete and FRP wrappings were used. Also, the internal and external connection failure conditions under the lateral loading have been investigated. The parameters studied in this study are hardness, ductility, shear strength, and energy absorption. The results showed that the use of the GFRP reinforcement instead of steel reinforcement improves its ductility, but reduces the bonding strength, shear bond strength and energy absorption. The results also showed that shear strength and energy absorption can be improved by reinforcing and enclosing the beam-to-column connection area.
