28-day Concrete Compressive Strength given Column Ultimate Strength Solution

STEP 0: Pre-Calculation Summary
Formula Used
28-Day Compressive Strength of Concrete = (Column Ultimate Strength-Yield Strength of Reinforcing Steel*Area of Steel Reinforcement)/(0.85*(Gross Area of Column-Area of Steel Reinforcement))
f'c = (P0-fy*Ast)/(0.85*(Ag-Ast))
This formula uses 5 Variables
Variables Used
28-Day Compressive Strength of Concrete - (Measured in Megapascal) - The 28-Day Compressive Strength of Concrete is the average compressive strength of concrete specimens that have been cured for 28 days.
Column Ultimate Strength - (Measured in Megapascal) - The Column Ultimate Strength with zero eccentricity of load.
Yield Strength of Reinforcing Steel - (Measured in Megapascal) - The Yield Strength of Reinforcing Steel is the maximum stress that can be applied before it begins to change shape permanently. This is an approximation of the elastic limit of the steel.
Area of Steel Reinforcement - (Measured in Square Millimeter) - The Area of Steel Reinforcement is the cross-sectional area of steel reinforcement.
Gross Area of Column - (Measured in Square Millimeter) - The Gross Area of Column is the total area enclosed by the column.
STEP 1: Convert Input(s) to Base Unit
Column Ultimate Strength: 2965.5 Megapascal --> 2965.5 Megapascal No Conversion Required
Yield Strength of Reinforcing Steel: 250 Megapascal --> 250 Megapascal No Conversion Required
Area of Steel Reinforcement: 7 Square Millimeter --> 7 Square Millimeter No Conversion Required
Gross Area of Column: 33 Square Millimeter --> 33 Square Millimeter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
f'c = (P0-fy*Ast)/(0.85*(Ag-Ast)) --> (2965.5-250*7)/(0.85*(33-7))
Evaluating ... ...
f'c = 55
STEP 3: Convert Result to Output's Unit
55000000 Pascal -->55 Megapascal (Check conversion here)
FINAL ANSWER
55 Megapascal <-- 28-Day Compressive Strength of Concrete
