Angle Steel

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.

The study deals with the effect of using Slurry infiltrated fiber concrete (SIFCON) with the reinforced concrete beams to explore its enhancement to the flexural capacity. The experimental work consists of the casting of six beams, two beams were fully cast by conventional concrete (CC) and SIFCON, as references. While the remaining was made by contributing a layer of SIFCON diverse in-depth and position, towards complete the overall depths of the built-up beam with conventional concrete CC. Also, an investigation was done through the control specimens testing about the mechanical properties of SIFCON. The results showed a stiffer behavior with a significant increase in load-carrying capacity when SIFCON used in tension zones. Otherwise high ductility and energy dissipation appeared when SIFCON placed in compression zones with a slight increment in ultimate load. The high volumetric ratio of steel fibers enabled SIFCON to magnificent tensile properties.
