In this paper, the results associated with modeling in the software ABAQUS Is presented. The model for connecting the beams to the reinforced concrete column for two modes with steel pins and also pendants of the genus GFRP is modeled and its related results have been studied. The parameters studied include the final strength of bonding, energy absorption and ductility. Based on the results of the final strength ratio at both steel and steel joints GFRP It can be seen that the replacement of steel reinforcements with reinforcements GFRP Leads to a decrease in the ultimate bond strength. The observed decline of 55% is obtained. Also, by comparing the energy absorption in two connections, the amateur steel and GFRP It is concluded that the cross section has higher ductility steel reinforcements. The degree of ductility reduction in the case of use of meshes GFRP Is equal to 37%. Finally, increasing the percentage of reinforcement in the beam during the use of the bars GFRP Leading to increasing capacity is very gradual but continuous circuit. With an increase in the number of weapon guns from 0.0044 to 0.0089 ( 2 fold increase ), the final capacity of the connection increased by 32% .
