Gross Cross-Sectional Area of Column given Total Allowable Axial Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gross Area of Column = Allowable Load/(0.25*Specified Compressive Strength at 28 Days+Allowable Stress in Vertical Reinforcement*Area Ratio of Cross Sectional Area to Gross Area)
A_g = P_allow/(0.25*f'_c+f'_s*p_g)
This formula uses 5 Variables

Variables Used

Gross Area of Column - (Measured in Square Meter) - Gross Area of Column is the total area enclosed by the column.
Allowable Load - (Measured in Newton) - Allowable load is the maximum working load that can be applied on the structure.
Specified Compressive Strength at 28 Days - (Measured in Pascal) - Specified Compressive Strength at 28 Days is the capacity of a material or structure to withstand loads tending to reduce the size, as opposed to which withstands loads tending to elongate.
Allowable Stress in Vertical Reinforcement - (Measured in Pascal) - Allowable Stress in Vertical Reinforcement is equal to 40 percent of the minimum yield strength, but not to exceed 30,000 lb/sq.in(207 MPa).
Area Ratio of Cross Sectional Area to Gross Area - Area Ratio of Cross Sectional Area to Gross Area is the ratio of cross-sectional area of vertical reinforcing steel to gross area of column.

STEP 1: Convert Input(s) to Base Unit

Allowable Load: 16.00001 Kilonewton --> 16000.01 Newton (Check conversion here)
Specified Compressive Strength at 28 Days: 80 Pascal --> 80 Pascal No Conversion Required
Allowable Stress in Vertical Reinforcement: 4.001 Newton per Square Millimeter --> 4001000 Pascal (Check conversion here)
Area Ratio of Cross Sectional Area to Gross Area: 8.01 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_g = P_allow/(0.25*f'_c+f'_s*p_g) --> 16000.01/(0.25*80+4001000*8.01)

Evaluating ... ...

A_g = 0.000499250968000217

STEP 3: Convert Result to Output's Unit

0.000499250968000217 Square Meter -->499.250968000217 Square Millimeter (Check conversion here)

FINAL ANSWER

499.250968000217 ≈ 499.251 Square Millimeter <-- Gross Area of Column
