  Considering the changes in design codes, many structures built in recent decades do not meet the requirements of the new codes. Therefore, in order to maintain the performance of these structures, it is necessary to retrofitting them. FRP materials are one of the suitable materials for strengthening structures against vibration loads such as earthquakes. However, due to the high cost of FRP and the difficulty of execution in the strengthening of existing structures, it is very important to provide new efficient methods for the use of these materials. For this reason, in the present study, the use of FRP strips for stregthening of beam to column joints was investigated and its effect on joint behavior was studied. For this purpose, ten models were introduced, modeled and analyzed with ABAQUS software. The results showed that the use of horizontal and diagonal strips on the beams increased the joint strength up to 37%. The final displacement of the beam also increased up to 102%. The present study showed that the use of FRP stripes is an effective technique for improving RC joints Manuscript profile
