Torsional behavior of steel fibers reinforced self-compacting concrete beams

Abstract EN

This research investigates experimentally torsional behavior of steel fibers reinforced self-compacting concrete beams with variables including steel fibers volume fraction(0.4% and 0.8%), reinforced with steel bars or non-reinforced self-compacting concrete beams and spacing of transverse steel bars reinforcement.

The experimental work includes investigation of nine beams tested under pure torsion and divided into three groups.

Group (A) represents the non-fibrous normal strength SCC beams.

Group (D) covers the fibrous normal strength SCC beams with steel fibers content (Vf) of 0.4%, and finally group (E) is fibrous normal strength SCC with steel fibers content (Vf) of 0.8%.

Test results are discussed based on torque-twist behavior.
