Force in Slab given Effective Concrete Area Solution

STEP 0: Pre-Calculation Summary

Formula Used

Slab Force = 0.85*Effective Concrete Area*28 Day Compressive Strength of Concrete
P_{on slab} = 0.85*A_concrete*f_c
This formula uses 3 Variables

Variables Used

Slab Force - (Measured in Newton) - Slab Force at maximum positive moments.
Effective Concrete Area - (Measured in Square Meter) - The effective concrete area is the total area of concrete enclosed with the steel reinforcement in the tension zone.
28 Day Compressive Strength of Concrete - (Measured in Pascal) - 28 Day Compressive Strength of Concrete is defined as the strength of the concrete after 28 days of using it.

STEP 1: Convert Input(s) to Base Unit

Effective Concrete Area: 19215.69 Square Millimeter --> 0.01921569 Square Meter (Check conversion here)
28 Day Compressive Strength of Concrete: 15 Megapascal --> 15000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_{on slab} = 0.85*A_concrete*f_c --> 0.85*0.01921569*15000000

Evaluating ... ...

P_{on slab} = 245000.0475

STEP 3: Convert Result to Output's Unit

245000.0475 Newton -->245.0000475 Kilonewton (Check conversion here)

FINAL ANSWER

245.0000475 ≈ 245 Kilonewton <-- Slab Force
