Çalışmada, betonarme kirişlerde Ultra Yüksek Perfromanslı Lifli Beton (UYPLB)
kullanımının, kiriş sünekliği, taşıma kapasitesi, eğilme rijitliği, kırılma şekilleri
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 161 MPa’lık basınç dayanımı elde edilmiştir.  Düşük ve yüksek 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.
