Steel fiber reinforced concretes behaviour under biaxial flexure

Abstract

En çok kullanılan yapı malzemelerinden biri olan beton gevreklik özelliği ile bilinir. Betonun gevreklik özelliğinin iyileştirilerek betona sünek davranış kazandırabilme çalışmalarına son günlerde ağırlık verilmiştir. Bu çalışmalardan bir kısmını da, beton içine liflerin katılması oluşturmaktadır. Kullanılan lifler çelik, cam, sentetik ve ahşap esaslı olabilir. Beton içine liflerin homojen bir şekilde karıştırılması ile elde edilen lifli beton park sahaları, havaalanı kaplamaları, erozyona maruz yüzeyler, köprü tabliyelerinde yoğun bir şekilde uygulanmaktadır. Bu çalışmada, iki eksenli eğilmeye maruz çelik lifli ve lifsiz plak numunelerin davranışları deneysel olarak incelenmiştir. Her bir numunenin deneyinden elde edilen yük-sehim eğrilerinden yararlanarak iki eksenli eğilmeye maruz çelik lifli ve lifsiz plak numunelerin davranışları karşılaştırılmıştır

Steel fiber reinforced concretes behaviour under biaxial flexure

Abstract

Concrete which is one of the most used structural material is recognized with brittle characteristics. Recently, the study of gaining ductile feature on concrete has been studied. One of these works is to add fibers in concrete. Fibers in concrete have different types such as steel, glass, synthetic and wood. Fiber concrete which is obtained by a mixture of cement, water, aggregate and fibers is often used in construction of bridge decks, airport pavements, parking areas subjected to cavitation and erosion surfaces. In this study, plain and steel fiber reinforced plate specimens’ behaviour subjected to biaxial flexure is examined experimentally. To compare plain and steel fiber reinforced plate specimens behaviour, the load-displacement curve of each specimen was obtained by experiments
