Bu çalışma kapsamında betonarme kiriş elemanlarda
beton sınıfı, beton tipi ve etriye oranının burulma davranışı üzerindeki etkisi
incelendi. Kiriş numunelerinin on iki âdeti geleneksel betonla sekiz âdeti ise
kendiliğinden yerleşen betonla üretildi. Beton sınıfı 20 MPa ile 40 MPa; beton
tipi geleneksel beton ile kendiliğinden yerleşen beton ve etriye aralığı olarak
da 80 mm ile 100 mm bu çalışmanın ana parametreleri seçildi. Kiriş
numunelerinin boyutları 250x300x1500 mm, boyuna donatı için 16 mm etriye için 8
mm donatı tasarlandı ve bu parametreler bütün numunelerde sabit tutuldu. Kiriş
numuneleri hazırlandıktan 28 gün sonra burulma momenti deneyine tabi tutuldu.
Burulma momentine tabi tutulan kirişlerin burulma momenti kapasiteleri ve dönme
açıları incelendi. Normal ve kendiliğinden yerleşen beton numunelerinin burulma
momenti kapasiteleri karşılaştırıldı. Aynı parametrelere sahip kendiliğinden
yerleşen beton numunelerinin daha yüksek burulma momenti kapasitelerine
ulaştığı deneysel olarak gözlemlendi. Benzer şekilde kendiliğinden yerleşen
beton numunelerinin dönme açılarının normal beton numunelerinin dönme
açılarından daha düşük olduğu belirlendi. Deneysel olarak ölçülen burulma
momenti değerleri Amerikan Standardı, Avrupa Standardı, Avustralya Standardı,
İngiliz Standardı ve Türk Standardına göre hesaplanan teorik burulma momenti
değerleri ile karşılaştırıldı. Deneysel sonuçlara en yakın değerler Avustralya
Standardında elde edildi.
