“…Based on their analytical results, the modified compression field theory was determined to be applicable for predicting the shear behavior with an effective estimation of the reorientation of the compressive struts with an increase in the load. Voo et al (2010) investigated the shear strength of prestressed UHPFRC I-beams without stirrups, according to the shear span-to-depth ratio (a/d) and the type of steel fibers. They indicated that a higher shear strength was obtained by using a higher fiber volume content and a lower a/d.…”

An overall review of the structural behaviors of ultra-high-performance fiber-reinforced concrete (UHPFRC) elements subjected to various loading conditions needs to be conducted to prevent duplicate research and to promote its practical applications. Thus, in this study, the behavior of various UHPFRC structures under different loading conditions, such as flexure, shear, torsion, and high-rate loads (impacts and blasts), were synthetically reviewed. In addition, the bond performance between UHPFRC and reinforcements, which is fundamental information for the structural performance of reinforced concrete structures, was investigated. The most widely used international recommendations for structural design with UHPFRC throughout the world (AFGC-SETRA and JSCE) were specifically introduced in terms of material models and flexural and shear design. Lastly, examples of practical applications of UHPFRC for both architectural and civil structures were examined.

“…Ancak bu tür betonların betonarme elemanlarda kullanımı ile ilgili çalışmalar kısıtlıdır. Yapılan çalışmalarda bu betonların geleneksel donatılı betonarme kiriş elemanlarda kullanımının önemli avantajlar sağlama potansiyeli rapor edilmiştir (Kamal et al 2014;Yang et al 2010;Stürwald and Fehling 2012;Dancygier and Savir 2006;Bertram and Hegger 2008;Voo et al 2010 …”

Anahtar kelimelerUltra yüksek performanslı lifli beton; Çelik lif; Betonarme kiriş; Eğilme davranışı. ÖzetÇalışmada, ultra yüksek performanslı lifli beton içeren betonarme kirişlerde eğilme davranışı bakımından etkin çelik lif tipinin deneysel olarak incelemesi yapılmıştır. Bunun için biri lifsiz, diğer dördü farklı çelik lif tipi içeren beş adet 100x150x1500 mm boyutlarında kiriş üzerinde eğilme testleri gerçekleştirilmiştir. Çalışmada 120 MPa üzeri basınç dayanımına sahip, hacimce %1.5 oranında çelik lif içeren beton kullanılmıştır. Lif olarak düz mikro lif tipi (F6), iki adet tek kancalı makro lif tipi (F30 ve F60_1) ve bir adet çift kancalı lif tipi (F60_2) incelenmiştir. Eğilmede etkin çelik lif tipi değerlendirmesi yerdeğiştirme süneklikleri, yük taşıma kapasiteleri ve çatlak özelliklerine göre yapılmıştır. Çalışmada elde edilen sonuçlardan; yük taşıma kapasitesi ve çatlakları sınırlandırma bakımından çift kancalı makro lifin (F60_2), yerdeğiştirme sünekliği bakımından ise düz mikro lifin (F6) en etkin lif olduğu belirlenmiştir.

AbstractThis study investigates the effective steel fiber type on ultra high performance fiber reinforced concrete beams with respect to flexural behavior. Five 100x150x1500 mm reinforced concrete beams, one is non-fiber and the others include four different steel fiber types, were tested in flexure. The concrete used in this study had compressive strength over 120 MPa and included 1.5% steel fibers by volume. Two types of hooked macro steel fibers (F30 and F60_1), double hooked macro (F60_2) and straight micro (F6) steel fibers were investigated. Evaluation of the effective steel fiber type on the flexural behavior were performed in terms of displacement ductility, load bearing capacity and cracking behavior. From the results of the study, it is determined that the most effective steel fiber for load bearing capacity and cracking control is double hooked steel fiber (F60_2) and most effective fiber for displacement ductility is straight micro fiber (F6).

“…The results showed that UHPC enhanced overall response of structures. Many of the structural tests on UHPC were under static loading condition [9]. Beyond affordability for full-scale tests, only a handful of them were conducted under impact or blast loads [4,10,11].…”
