## Stress in Compressive Steel Solution

STEP 0: Pre-Calculation Summary
Formula Used
stress_in_compressive_steel = (Distance from compression fiber to NA-Effective cover/(Centroidal distance of tension reinforcement-Distance from compression fiber to NA))*(2*steel stress)
f's = (Kd-d'/(d-Kd))*(2*fs)
This formula uses 4 Variables
Variables Used
Distance from compression fiber to NA - Distance from compression fiber to NA is the distance from the extreme compression fiber or surface to the neutral axis. (Measured in Millimeter)
Effective cover - Effective cover is the distance from exposed surface of concrete to the centroid of main reinforcement. (Measured in Millimeter)
Centroidal distance of tension reinforcement - Centroidal distance of tension reinforcement is the distance measured from eternal fiber to centroid of tension reinforcement. (Measured in Millimeter)
steel stress - steel stress is the stress developed in steel (Measured in Kilopound Per Square Inch)
