The beam is the element that carries transverse external loads that cause bending moment, shear forces and in some cases torsion. Concrete is the most often used in construction and it’s strong in compression and very weak in tension. Steel reinforcement is used to take up tensile stresses in reinforced concrete beams. Mild steel bars or Deformed or High yield strength deformed bars (HYSD) are used. HYSD bars have ribs on the surface, increasing the bond strength by at least 40%.
Good detailing of reinforcements with proper drawings is essential at the site to provide a good construction process. These drawings generally also include a bar bending schedule. The bar bending schedule describes the length and number, position and shape of the bar.
