Minimum cover in beams must be 25 mm or shall not be less than the larger diameter of bar for all steel reinforcement including links.

Distribute minimum 0.1% of the web area equally on two faces at a spacing not exceeding 300 mm or web thickness, whichever is less.

Side face reinforcement in the web of the beam provided when the depth of the web in a beam exceeds 750 mm.

Shear reinforcements in the form of vertical stirrups and or bent up longitudinal bars.

Longitudinal reinforcement at tension and compression face.

Generally a beam consists of following steel reinforcements: These bars shall withstand compressive stresses and are provided with reinforcement in compression face.īeams when subjected to torsion are provided additional longitudinal and shear reinforcement to resist bending and shear stresses developed due to torsion.

When depth of section is restricted due to reasons such as architectural reasons, or basement floors, the beam section is designed as doubly reinforced concrete beam. These additional reinforcement are of nominal diameter of 8mm or 10mm.

In practice, for singly reinforced beams, two additional bars are provided in compression face of the beam so that stirrups can be tied with bars. Reinforcement are provided to resist tensile stresses due to bending and shear in beams for singly reinforced sections. Simply supported, fixed, continuous and cantilever beamsīased on embedded reinforcement Singly reinforced The beam is generally designed as simple beam but additional reinforcement provided on top with slab to make it behave like a Tee-beam.įig.2: Slab-Beam Details According to supporting conditions When a beam is designed with slab, called slab beam or Tee-beam, reinforcements are provided as shown in figure below.

HYSD bars have ribs on the surface and this increases the bond strength at least by 40%.

Mild steel bars or Deformed or High yield strength deformed bars (HYSD) used.

Steel reinforcement counter act tensile stresses in reinforced concrete beams.

Concrete is strong in compression and very weak in tension.

Beam carries transverse external loads that cause bending moment, shear forces and in some cases torsion.

Nominal area: 0.2 square inches (129 square millimeters)Īt Harris Supply Solutions, we continually strive to ensure that our product offerings reflect the latest technological developments and construction industry trends.

Nominal diameter: 0.5 inches (12.7 millimeters).

Weight per unit length: 0.668 pounds per foot (0.996 kilograms per meter).

It is often trusted as a strengthening material in slabs, piers, columns, and walls. This 1/2 inch rebar grade is known as “13MM' in the metric system. In particular, #4 reinforcement steel is used to pave roads and highways, and in certain climates, it can also be used to build swimming pool frames. This common, high-grade rebar has widespread applications in the residential and light commercial construction industries. Harris Supply Solutions offers #4 reinforcing bar, also called #4 rebar, which is made from a sturdy composite of carbon steel.
