“…Besides, researches had shown that, a big majority of the existing reinforced concrete (RC) buildings in Van-Ercis earthquake are seismically deficient (EERC, 2011). These deficiencies were low-strength materials, no column stirrups at the beam-column joints, strong beam-weak column formation, no confinement zones at the end of the columns beams, and wide spacing of beam and column stirrups (EERC, 2011;Bahadır and Balık, 2017). Because of these deficiencies, these buildings had an insufficient lateral load carrying capacity, lateral stiffness, energy dissipation capacity and ductility.…”

ÖZET: Bu deneysel çalışmadaki amaç, iki güçlendirme methodunda pencere boşluğunun kısa kolon davranışına etkilerini araştırmaktır. Bu çalışmada, iki katlı, 1/5 ölçekli ve tek açıklıklı yedi betonarme çerçeve üretilmiştir. Numuneler, Türkiye'de konut binalarında yaygın olarak görülen çeşitli eksiklikleri içermektedir. Bu numuneler, sabit düşey yük ve yatay yükleme altında test edilmiştir. Birinci numune referans boş çerçeve olarak üretilmiştir. İkinci ve üçüncü numuneler gaz beton bloklu dolgu duvarlı olarak üretilmiştir. Dördüncü ve beşinci numuneler betonarme dolgu duvarları ile güçlendirilmiştir. Altıncı ve yedinci numuneler ise dıştan betonarme duvarlı ve betonarme kolon mantolu olarak güçlendirilmiştir. Tüm numunelerin duvarları, kısa kolon davranışının etkilerini araştırmak için iki farklı pencere boşluğu ile üretilmiştir. Test sonuçları göstermiştir ki, uygulanan güçlendirme yöntemleri, betonarme çerçevenin, yatay yük taşıma kapasitesini, enerji tüketme kapasitesini ve başlangıç rijitliğini önemli derecede artırmıştır. Betonarme kolon mantosu sayesinde dıştan betonarme duvarlı numunelerde kısa kolon davranışı önlenmiştir.Anahtar kelimeler: Betonarme çerçeveler, tersinir tekrarlanır yatay yükleme, güçlendirme, pencere açıklıkları. ABSTRACT:The purpose of in this experimental study is to investigate the effects of short column behavior due to window opening at two strengthening methods. At this study, seven reinforced concrete frames as two stories, 1/5 scaled and one bay were produced. The specimens contained several deficiencies that were commonly observed in residential buildings in Turkey. These specimens were tested under lateral loading and constant vertical loading. First specimen was produced as the reference bare frame. Second and third specimens were produced with infill autoclaved aerated concrete blocks wall. Fourth and fifth specimens were strengthened with infill RC shear wall. Sixth and seventh specimens were strengthened with external RC shear wall and RC column jackets. The walls of all specimens were manufactured with two different windows opening to investigate the effects of short column behavior. The test results showed that these applied strengthening methods have significantly increased the lateral load carrying and energy dissipation capacities, initial stiffness of the RC frame. Thanks to RC column jackets, at specimens with the external RC shear wall was prevented to the short column behavior.

In the design of earthquake-resistant reinforced-concrete structural systems, the necessity to construct a regular structure is one of the main principles. Building irregularities generally become obvious with the effect of a seismic load. It is crucial that the irregularities of structural systems should be considered properly with respect to the conditions determined by the building codes. In this study, the soft-storey irregularity that causes most of the losses and damage in earthquakes was investigated with respect to the criterions of various national building codes. Eleven sub-models were produced on the basis of a general building model, and they were analyzed with respect to the conditions of the codes relating to the soft-storey phenomenon using the SAP 2000 structural-analysis program. The first-storey heights of the models were different from each other while all the other parameters and the geometries were the same. In this way, the codes were compared in terms of the effect of the storey height on the formation of a soft storey. Eventually, it was observed that, especially in the Japanese Seismic Code, the soft-storey irregularity is handled very sensibly and safely.

In this experimental study; five RC frames with a scale of 1/5, single spans and two storey were produced so as to reflect the characteristics of existing structures. Two RC frames were used as the reference specimens that without an infill wall and autoclaved aerated concrete blocks (AAC) infilled wall. Three of these RC frames were strengthened as CFS (Cold Formed Steel) drywall system, infill RC shear wall and both external RC shear wall and column jacketing. All specimens produced were tested under reverse cyclic lateral loading and constant vertical loading. Strength, stiffness and energy dissipation capacities of all test specimens are compared with each other. The lateral load carrying capacity and energy dissipation capacities of strengthened specimens have occurred higher than reference specimens. But initial stiffness and stiffness at the max lateral load of specimen strengthened with CFS drywall system have occurred lower than reference specimen with AACW.
