Abstract:

 In this study, improving the behavior of short column region by means of higher energy consumption and higher shear load carrying capacity is aimed. For this purpose, a special kind of concrete with high steel fiber ratio SIFCON is used for coating of column and placing rubber dampers around the short column region was proposed. As a result, its seen that; the SIFCON coating increased the shear force carrying capacity of short column by 2,18 times when compared with non-retrofitted specimen, whereas additional rubber dampers around the short column region increased the total load carried by 4 times. Also, the energy dissipation of the region increased by 2,02 to 2,82 times when compared with non-retrofitted situation. As a result, it was seen that, with a practical approach it is possible to improve the behavior of short columns.

 Bu çalışmada, kısa kolon bölgesinin davranışının daha yüksek enerji tüketimi ve daha yüksek kesme kuvveti taşıma kapasitesi açısından iyileştirilmesi amaçlanmaktadır. Bu amaçla, kolon mantolanması için yüksek çelik lif oranına sahip özel bir beton SIFCON kullanılmış ve kısa kolon bölgesinin çevresine kauçuk sönümleyiciler yerleştirilmesi önerilmiştir. Sonuç olarak görülmüştür ki; SIFCON mantolaması, güçlendirilmemiş numuneye kıyasla kısa kolonun kesme kuvveti taşıma kapasitesini 2,18 kat arttırırken, kısa kolon bölgesi etrafında ilave kauçuk sönümleyici kullanılırsa, kesme kuvveti kapasitesi güçlendirilmemiş kolona nazaran 4 kat arttırılmıştır. Ayrıca, bölgenin enerji tüketimi, güçlendirme yapılmayan duruma göre 2,02 ila 2,82 katına çıkmıştır. Sonuç olarak, pratik bir yaklaşımla, kısa kolonların davranışını iyileştirmenin mümkün olduğu görülmüştür.
