Abstract

In the construction industry, which is constantly evolving and open to new technologies, concrete has been used to build constructions and has great importance, but unless enough vibration application during casting process, occur gaps between the concrete components, therefore the physical and mechanical properties of concrete cannot be forecasted accurately. Self-compacting concrete does not require vibration or compaction, it saves workmanship and time, and has high performance. Because of less workmanship and shorter production time, the self-compacting concretes offer the possibility of making the construction more economical. In this study, the flexural behavior of the reinforced concrete beams produced with self-compacting and normal concrete were investigated in terms of damage mechanics. Flexural behavior, shear capacity, energy absorption capacity and fracture type of both concrete types was investigated and results were compared. Variables of the samples are the ratio of the stirrup, and the concrete type. Totally 8 pieces of 1/2 scale beams used in this study. The specimens tested with 4-point bending test. When all the results were examined, it was observed that the beams produced with self-compacting concrete consumed more energy.

KENDİLİĞİNDEN YERLEŞEN VE NORMAL BETON İLE ÜRETİLMİŞ BETONARME KİRİŞLERİN EĞİLME DAVRANIŞININ İNCELENMESİ

Abstract

Sürekli gelişen ve yeni teknolojilere açık olan inşaat endüstrisinde beton, inşaatlar için kullanılmıştır ve büyük önem taşımaktadır, fakat döküm işlemi sırasında yeterli titreşim uygulaması yapılmazsa, beton bileşenler arasında boşluklar oluşur, bu nedenle betonun fiziksel ve mekanik özellikleri doğru bir şekilde tahmin edilemez. Kendiliğinden yerleşen beton, titreşim veya sıkıştırma işlemi gerektirmez, işçilik ve zaman tasarrufu sağlar ve yüksek performansa sahiptir. Daha az işçilik ve daha kısa döküm süresi nedeniyle, kendiliğinden yerleşen betonlar inşaatı daha ekonomik hale getirme imkanı sunar. Bu çalışmada, kendiliğinden yerleşen ve normal beton ile üretilmiş betonarme kirişlerin eğilme davranışları hasar mekaniği açısından incelenmiştir. Her iki beton türünde eğilme davranışı, kayma kapasitesi, enerji yutma kapasitesi ve kırılma tipi araştırılmış ve sonuçlar karşılaştırılmıştır. Numunelerin değişkenleri etriye aralığı ve beton tipidir. Bu çalışmada toplam 8 adet 1/2 ölçekli kiriş kullanılmıştır. Numuneler 4 noktalı eğilme düzeneği ile test edilmiştir. Tüm sonuçlar incelendiğinde, kendiliğinden yerleşen betonla üretilen kirişlerin daha fazla enerji tükettiği gözlenmiştir.
