Abstract

This 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).

Özet

Çalışmada, 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.
