AB  - Thepurpose of in this experimental study is to investigate the effects of shortcolumn behavior due to window opening at two strengthening methods. At thisstudy, seven reinforced concrete frames as two stories, 1/5 scaled and one baywere produced. The specimens contained several deficiencies that were commonlyobserved in residential buildings in Turkey. These specimens were tested underlateral loading and constant vertical loading. First specimen was produced asthe reference bare frame. Second and third specimens were produced with infillautoclaved aerated concrete blocks wall. Fourth and fifth specimens werestrengthened with infill RC shear wall. Sixth and seventh specimens werestrengthened with external RC shear wall and RC column jackets. The walls ofall specimens were manufactured with two different windows opening toinvestigate the effects of short column behavior. The test results showed thatthese applied strengthening methods have significantly increased the lateralload carrying and energy dissipation capacities, initial stiffness of the RCframe. Thanks to RC column jackets, at specimens with the external RC shearwall was prevented to the short column behavior.

N2  - Bu deneysel çalışmadaki amaç, iki güçlendirmemethodunda pencere boşluğunun kısa kolon davranışına etkilerini araştırmaktır.Bu çalışmada, iki katlı, 1/5 ölçekli ve tek açıklıklı yedi betonarme çerçeveüretilmiştir. Numuneler, Türkiye'de konut binalarında yaygın olarak görülençeşitli eksiklikleri içermektedir. Bunumuneler, sabit düşey yük ve yatay yükleme altında test edilmiştir. Birincinumune referans boş çerçeve olarak üretilmiştir. İkinci ve üçüncü numuneler gazbeton bloklu dolgu duvarlı olarak üretilmiştir. Dördüncü ve beşinci numunelerbetonarme dolgu duvarları ile güçlendirilmiştir. Altıncı ve yedinci numunelerise dıştan betonarme duvarlı ve betonarme kolon mantolu olarakgüçlendirilmiştir. Tüm numunelerin duvarları, kısa kolon davranışının etkileriniaraştırmak için iki farklı pencere boşluğu ile üretilmiştir. Test sonuçlarıgöstermiştir ki, uygulanan güçlendirme yöntemleri, betonarme çerçevenin, yatayyük taşıma kapasitesini, enerji tüketme kapasitesini ve başlangıç rijitliğiniönemli derecede artırmıştır. Betonarme kolon mantosu sayesinde dıştan betonarmeduvarlı numunelerde kısa kolon davranışı önlenmiştir.
