Abstract
In this study; the effect of axial load, longitudinal reinforcement diameter, transverse
reinforcement diameter and transverse reinforcement spacing were investigated on the moment curvature
relationships of reinforced concrete columns. Reinforced concrete columns having different geometries
were designed considering the regulations of Turkish Building Earthquake Codes (2018). Investigations
of the effect of axial load, longitudinal reinforcement diameter, transverse reinforcement diameter and
transverse reinforcement spacing on the behavior of the concrete columns are the main purpose of this
study. The behavior of the columns was investigated from the moment-curvature relation, by considering
the nonlinear behavior of the materials taken into account. The moment-curvature relationships of the
reinforced concrete column cross-sections having different axial load levels have been obtained by
considering Mander model which considers the lateral confined concrete strength. The examined effects
of the parameters on the column behavior were evaluated in terms of curvature ductility and the moment
capacity of the cross-section. In the designed column cross-sections, different parameters effecting the
moment-curvature relationships were calculated and compared. It is observed that the variation of the
axial load, longitudinal reinforcement diameter, transverse reinforcement diameter and transverse
reinforcement spacing have an important effect on the moment-curvature behavior of the reinforced
concrete columns.

Bu çalışmada; eksenel yük, boyuna donatı çapı, sargı donatı çapı ve sargı donatı aralığının
değişiminin betonarme kolonların moment-eğrilik ilişkisine olan etkisi incelenmiştir. Farklı geometriye
sahip betonarme kolon modelleri Türkiye Bina Deprem Yönetmeliği (2018) hükümlerine uyularak tasarlanmıştır. Farklı geometri ve alana sahip betonarme kolon modellerinin davranışına eksenel yük,
boyuna donatı çapı, sargı donatı çapı ve sargı donatı aralığının etkisinin araştırılması bu çalışmanın
amacını oluşturmaktadır. Betonarme kolonların davranışı, malzemelerin doğrusal olmayan davranışları
göz önüne alınarak moment-eğrilik ilişkisi üzerinden elde edilmiştir. Betonarme kolon kesitlerinin
moment-eğrilik ilişkileri farklı eksenel yük seviyeleri için yanal sargı basıncını göz önüne alan Mander
modeli ile elde edilmiştir. İncelenen parametrelerin kolon davranışına etkileri, eğrilik sünekliği ve kesit
dayanımı açısından değerlendirilmiştir. Tasarlanan betonarme kolon kesitlerde, farklı parametrelerin
moment eğrilik ilişkisi üzerindeki etkisi hesaplanarak karşılaştırılmıştır. Eksenel yük, boyuna donatı çapı,
sargı donatı çapı ve sargı donatı aralığının değişiminin, betonarme kolonların moment-eğrilik davranışı
üzerinde önemli bir etkiye sahip olduğu gözlenmiştir.
