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.
This post is very efficetive to me
We recently started using HYSD bars in favor of TMT bars for the climate here in Texas and our client’s commercial brick and masonry work. While we like the more elastic properties of TMT, we find HYSD bars help more with the reinforcement of the concrete during construction. Thank you for the clear and well-written explanation.
