Buckling Stress given Maximum Strength Solution

STEP 0: Pre-Calculation Summary

Formula Used

Buckling Stress = Strength of Column/(0.85*Gross Effective Area of Column)
F_cr = P_u/(0.85*A_g)
This formula uses 3 Variables

Variables Used

Buckling Stress - (Measured in Pascal) - Buckling Stress is the stress developed due to a sudden change in shape of a structural component under load, such as the bowing of a column under compression.
Strength of Column - (Measured in Newton) - Strength of Column is the maximum load that a column can hold before failing.
Gross Effective Area of Column - (Measured in Square Meter) - Gross Effective Area of Column cross section is the total area enclosed by the column including concrete and steel area.

STEP 1: Convert Input(s) to Base Unit

Strength of Column: 1054 Kilonewton --> 1054000 Newton (Check conversion here)
Gross Effective Area of Column: 5000 Square Millimeter --> 0.005 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_cr = P_u/(0.85*A_g) --> 1054000/(0.85*0.005)

Evaluating ... ...

F_cr = 248000000

STEP 3: Convert Result to Output's Unit

248000000 Pascal -->248 Megapascal (Check conversion here)

FINAL ANSWER

248 Megapascal <-- Buckling Stress

(Calculation completed in 00.007 seconds)
