Concrete is a brittle material and weak in tension. Traditionally, web
reinforcement in the form of vertical stirrups is used in reinforced
concrete (RC) beams to take care of principal stresses that may cause
failure when they are subjected to shear stresses. In recent decades,
the potential of various types of fibers for improving post-cracking
behavior of RC beams and replacing stirrups completely or partially have
been studied. It has been shown that the use of steel fibers randomly
dispersed and oriented in concrete has a significant potential for
enhancing mechanical properties of RC beams. However, the studies on
deep steel fiber reinforced concrete (SFRC) beams are limited when
compared to those focusing on slender beams. An experimental program
consisting of three RC and nine SFRC deep beams without stirrups were
conducted in this study. Besides, various models developed for
predicting the ultimate shear strength and diagonal cracking strength of
SFRC deep beams without stirrups were applied to experimental data
obtained from the literature and this study.
