Behavior of steel fiber self-compacting concrete hollow deep beams under torque

الملخص EN

The purpose of this paper was concerned of the behavior of six samples of deep beams under the influence of pure torsion.

Such samples were self-compacting concrete (SCC) and two ratios of Steel Fibers (SF (were also added (0.75 % and 1.5 % ).

This study examined the behavior of the samples when pure torsion was applied and reacted to angles of torsion, longitudinal strains and concrete strains.

It was obvious from the results of the test that the addition of steel fiber to the SCC mixture increased the strength of the compression and tensile strength, which increased the hardness of the samples, thereby decreasing the response of the samples to the angle of twisting, longitudinal strains of concrete and concrete The purpose of this paper was concerned of the behavior of six samples of deep beams under the influence of pure torsion.
