Abstract

In this study, the effects of using Ultra High Performance Fiber Reinforced Concrete (UHPFRC) on ductility, load bearing capacity, flexural stiffness, failure mode and cracking behavior of reinforced concrete (RC) beams were experimentally investigated. 150x250x2500 mm test beams with rectangular cross sections were used. Straight micro and hooked macro steel fibers were used together in the concrete and average compressive strength of 163 MPa was achieved. A total of nine RC test beams, with and without fibers, consisting of four different tensile reinforcement ratios were tested under four point bending and their flexural behaviors were investigated. The results of the study showed that the use of UHPFRC in the beams provided significant advantages in terms of investigated parameters.

Özet

Çalışmada, Ultra Yüksek Performanslı Lifli Beton (UYPLB) kullanımının betonarme kirişlerin sünekliği, taşıma kapasitesi, eğilme rijitliği, kırılma şekli ve çatlak davranışı üzerindeki etkileri deneysel olarak incelenmiştir. Bunun için dikdörtgen enkesitli 150x250x2500mm boyutlarında test kirişleri kullanılmıştır. Beton içeriğinde düz mikro ve kancalı makro boyutta çelik lifler karma olarak kullanılmış ve ortalama 163 MPa’lık basınç dayanımı elde edilmiştir. Dört farklı çekme donatısı oranına sahip lifli ve lifsiz toplam dokuz adet betonarme test kirişi üzerinde dört noktalı eğilme testleri gerçekleştirilmiş ve salt eğilme davranışları incelenmiştir. Çalışmadan elde edilen sonuçlar, kirişlerde UYPLB kullanımının incelenen parametreler bakımından önemli avantajlar sağladığını göstermiştir.
