Abstract :Abstract: In that study, the formerly proposed method for seismic retrofitting of RC frames with fiber reinforced lightweight panels and polymer binders were re-tested with full scale frames for the first time in a numerical analysis performed by Abaqus . Later, modelling was performed with beam elements and equivalent strut approach in Sap2000 and a validation of modelling was done. Then ,the method was applied to 3 story and 5 story frames by using beam elements and equivalent strut approach in Sap2000. Proposed method increased the lateral load capacity by 2.76 times if compared with traditionally infilled frame according to the analysis done in single story frames. In 3 story frames, proposed method increased the lateral load capacity by 3 times and in 5 story frames by 3.18 times if the retrofitted specimens were compared with traditionally infilled structures. Also, the proposed method is effective for increasing stiffness of structures.
