Experimental Study on Torsion Behaviors of Angle Steel Reinforced Concrete Beams

In order to research the mechanical property of angle steel reinforced concrete beams, 7 specimens were designed for pure torsion experiment. And three running parameters which are sectional steel disposition, thickness of concrete cover and concrete strength are taken into consideration. Base on the test, the torque-torsion angle curve, torque-strain curve, cracking torque, ultimate torque and other important data are obtain. The influences of those parameters are analyzed.
