Maximum Strength for Compression Members Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Gross Effective Area of Column: 5000 Square Millimeter --> 0.005 Square Meter (Check conversion here)
Buckling Stress: 248 Megapascal --> 248000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_u = 0.85*A_g*F_cr --> 0.85*0.005*248000000

Evaluating ... ...

P_u = 1054000

STEP 3: Convert Result to Output's Unit

1054000 Newton -->1054 Kilonewton (Check conversion here)

FINAL ANSWER

1054 Kilonewton <-- Strength of Column

What is Maximum Strength for Compression Members?

For a compression member, such as a column, the loading capacity of a short column is determined by strength limit of the material. The strength of a column of intermediate size is limited by its degree of inelasticity. A long column is constrained by the elastic limit. Ability to resist load is defined as maximum strength of members.

How to Calculate Maximum Strength for Compression Members?

Maximum Strength for Compression Members calculator uses Strength of Column = 0.85*Gross Effective Area of Column*Buckling Stress to calculate the Strength of Column, The Maximum Strength for Compression Members formula is defined as the maximum loading capacity of it and is determined by the strength limit of the material. Strength of Column is denoted by P_u symbol.

How to calculate Maximum Strength for Compression Members using this online calculator? To use this online calculator for Maximum Strength for Compression Members, enter Gross Effective Area of Column (A_g) & Buckling Stress (F_cr) and hit the calculate button. Here is how the Maximum Strength for Compression Members calculation can be explained with given input values -> 1.054 = 0.85*0.005*248000000.
