Using the following details, Design the shear reinforcement along the length of the beam if it is reinforced with 3-25mm diameter rebars. Sketch the stirrup pattern. Unit Weight of Concrete = 23.123 kN per cu.m. Shear Strength Reduction Factor = 0.75 %3D %3D Clear Cover = 40 mm Beam dimension is 300mm x 500mm Stirrups, f = 275 MPa Main Reinforcing Steel, fy = 415 MPa Concrete, fc' = 27.5 MPa. The 3-m-span cantilever beam (the free end on the right side) carries a uniform dead load of 30 kN/m (Beam weight not included), and a varying live load of 15 kN/m that reduces to zero at the end of the beam.

Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.
