|
Steel fibers have been widely used in the construction industry for the erection of structural members such as beams, columns and slabs to improve their mechanical properties. This paper deals with the torsional behaviour of reinforced beams having steel fibers tested under pure torsion. A total of five beams consists of one conventional beam and four beams containing steel fiber. The steel fibers are added in a volume fraction of 0.5%, 1.0%, 1.5% and 2%. Hooked-end steel fibers were used with an aspect ratio of 66. The shape and aspect ratio was kept constant for all the beams. Test results include first cracking torque, ultimate torque and twist angles. The use of steel fibers in the volume fraction of 1.5% and 2% exhibited greater torque and twist angles. Therefore the results revealed that higher volume fraction of steel fibers improve the torsional performance of RC beams. |
