Calculator for Strength of doubly Reinforced Concrete beam with one layer of tension rebar (FPS/US Customary Units)


Reinforced concrete beam

This calculator is useful for doubly reinforced rectangular concrete beam with one layer of tension re-bar. This calculator uses FPS/US Customary Units. You can also use it for singly reinforced section, just by entering compression rebar equal to zero.

Effective depth is measured from the top edge to the centroid of tension rebar. This calculator uses the concept of Whitney's stress block and measures the depth of stress block "a" from the top edge. The user of this calculator is advised to comply with ACI guidelines for beam width, thickness, rebar spacing and cover etc.

This calculator also determines the minimum area of tension rebar required for crack control and balanced steel area required for a balanced section.

This calculator assumes a strirrp of #3 and maximum rebar of #11. It also calculates minimum beam width required. This calculator also calculates the strain in tension steel and compression steel to ascertain yielding of steel. There should be atleast 2 rebars and atmost 6 rebars in a single layer.
