Beam-column joints require a high ductility during the unexpected loadings that necessitate the
need for ductile concrete in such unprotected locations. Alternatively, self-compacting concrete (SCC) is
a sort of concrete which has generated tremendous interest throughout the last decades in order to reach a
ductile structural elements during the seismic actions. Specific properties of this type of concrete include
high performance, high resistance against segregation and needless to internal or external vibration in
order to compact. In the seismic regions, ductility is one of the most important factors in the design of
reinforced concrete (RC) members, especially structural joints flexural performance; it is due to the
enhance in the capability of plastic deformability. This paper describes load-displacement behavior of
experimental and theoretical analysis of four SCC beam-column joints with different percentage of the
ratio of the reinforcing bars (ρ). In the theoretical phase of this investigation three-dimensional nonlinear
finite element method (FEM) model i.e., Seismostruct was used and the load-deflection diagrams were
plotted to compare the test results with the numerical output. The experimental results and nonlinear FEM
modeling indicate that using SCC as a workable concrete in beam-column joints of reinforced concrete
structures has satisfactory performance in terms of ductility and energy dissipations.

Kendiliğinden Yerleşen Betonla Yapılan Kolon-Kiriş Birleşimlerinde Donatı Oranı Etkisinin Değerlendirilmesi

Yüksek süneklik gerektiren kolon-kiriş düğüm noktaları gibi korunmasız bölgelerde, beklenmedik
yüklemeler altında, sünek betona ihtiyaç duyulmaktadır. Alternatif olarak, kendiliğinden yerleşen beton
(KYB), deprem etkisi altinda elemanların daha sünek davranış gösteren bir yapıya ulaşmak için son
yıllarda büyük ilgi yaratan bir beton türüdür. Bu tipteki betonların belirgin özellikleri yüksek performans,
segregasyona karşı yüksek direnç ve yerleşme için iç veya dış vibrasyona ihtiyaç duyulmamasıdır.
Deprem bölgelerinde, süneklik, özellikle eğilmeye maruz kalan yapısal bağlantı noktalarının
performansında önemli bir faktördür ve bu davranış plastik yerdeğiştirme kapasitesindeki artıştan
kaynaklanmaktadır. Bu makalede, KYB kullanılan ve farklı donatı oranlarındaki dört adet kolon-kiriş
düğüm noktasının yük-yerdeğiştirme davranışının deneysel ve teorik analizleri açıklanmaktadır. Bu
araştırmanın teorik aşamasında, üç boyutlu sonlu elemanlar metodu (SEM), Seismostruct doğrusal
olmayan yazılımı kullanılarak, deneysel-nümerik sonuçlar karşılaştırılmış ve yük-yerdeğiştirme
diyagramları çizdirilmiştir. Deneysel sonuçlar ve doğrusal olmayan SEM modeli, kolon-kiriş düğüm
noktalarında işlenebilir beton olarak KYB’un kullanımının, betonarme yapılarda süneklik ve enerji yutma
kapasitesi bakımından tatmin edici bir performansa sahip olduğunu göstermiştir.
