Cross-Sectional Area of Compressive Reinforcing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Compression Reinforcement = (Bending Moment of Considered Section-Bending Moment of Singly reinforced Beam)/(Modular Ratio*Extreme Compressive Stress of Concrete*Effective Depth of Beam)
A_s' = (B_M-M')/(m*f_EC*d_eff)
This formula uses 6 Variables

Variables Used

Area of Compression Reinforcement - (Measured in Square Meter) - Area of Compression Reinforcement is the amount of steel required in the compression zone.
Bending Moment of Considered Section - (Measured in Newton Meter) - Bending Moment of Considered Section is defined as the sum of moment of all forces acting on one side of the beam or section.
Bending Moment of Singly reinforced Beam - (Measured in Newton Meter) - Bending Moment of Singly reinforced Beam is the bending moment that would be carried by a beam of balanced design and same dimensions with tensile reinforcing only.
Modular Ratio - Modular Ratio is the ratio of modulus of elasticity of steel and concrete. Concrete has varying moduli as it is not a perfectly elastic material. essentially, m= Es/Ec.
Extreme Compressive Stress of Concrete - (Measured in Pascal) - Extreme Compressive Stress of Concrete is the stress on the extreme fiber of concrete surface.
Effective Depth of Beam - (Measured in Meter) - Effective Depth of Beam is the distance from the centroid of tension steel to the outermost face of the compression fiber.

STEP 1: Convert Input(s) to Base Unit

Bending Moment of Considered Section: 49.5 Kilonewton Meter --> 49500 Newton Meter (Check conversion here)
Bending Moment of Singly reinforced Beam: 16.5 Kilonewton Meter --> 16500 Newton Meter (Check conversion here)
Modular Ratio: 8 --> No Conversion Required
Extreme Compressive Stress of Concrete: 50.03 Megapascal --> 50030000 Pascal (Check conversion here)
