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. KW - Polymer binder KW - Abaqus KW - Sap2000 KW - Strengthening KW - Concrete Panel N2 - Özet: Bu çalışmada, betonarme çerçevelerin fiber takviyeli hafif paneller ve polimer bağlayıcılarla sismik olarak güçlendirilmesi için daha önce önerilen yöntem, Abaqus tarafından gerçekleştirilen sayısal bir analizde ilk kez tam ölçekli çerçevelerle yeniden test edildi. Daha sonra Sap2000'de kiriş elemanları ve eşdeğer dikme yaklaşımıyla modelleme yapılarak modellemenin doğrulanması yapılmıştır. Daha sonra yöntem Sap2000'de kiriş elemanları ve eşdeğer dikme yaklaşımı kullanılarak 3 katlı ve 5 katlı çerçevelere uygulanmıştır. Önerilen yöntem, tek katlı çerçevelerde yapılan analize göre, geleneksel dolgulu çerçevelerle karşılaştırıldığında yanal yük kapasitesini 2,76 kat artırmıştır. Önerilen yöntem, güçlendirilmiş numuneler geleneksel dolgulu yapılarla karşılaştırıldığında, 3 katlı çerçevelerde yanal yük kapasitesini 3 kat, 5 katlı çerçevelerde ise 3,18 kat artırmıştır. Ayrıca önerilen yöntem yapıların rijitliğini arttırmada da etkilidir. CR - [1] Parsons T., Toda S., Stein, R.,S., Barka, A., Dieterich, J., H. 2000.
