Column Ultimate Strength with Zero Eccentricity of Load Solution

Follow our step by step solution on how to calculate Column Ultimate Strength with Zero Eccentricity of Load?

FIRST Step Consider the formula
P0=0.85⋅f'c⋅(Ag-Ast)+fy⋅Ast
Next Step Substitute values of Variables
∴ P0=0.85⋅55MPa⋅(33mm²-7mm²)+250MPa⋅7mm²
Next Step Prepare to Evaluate
∴ P0=0.85⋅55⋅(33-7)+250⋅7
Next Step Evaluate
∴P0=2965500000Pa
LAST Step Convert to Output's Unit
∴P0=2965.5MPa
