Allowable Compression Stress when Slenderness Ratio is less than Cc Solution

STEP 0: Pre-Calculation Summary

Formula Used

Allowable Compression Stress = (1-((Slenderness Ratio^2)/(2*Value of Cc^2)))/((5/3)+(3*Slenderness Ratio/(8*Value of Cc))-((Slenderness Ratio^3)/(8*(Value of Cc^3))))*Minimum Specified Yield Stress of Steel
F_a = (1-((λ^2)/(2*C_c^2)))/((5/3)+(3*λ/(8*C_c))-((λ^3)/(8*(C_c^3))))*F_y
This formula uses 4 Variables

Variables Used

Allowable Compression Stress - (Measured in Pascal) - The Allowable Compression Stress is the maximum stress (tensile, compressive or bending) that is allowed to be applied to a structural material.
Slenderness Ratio - Slenderness Ratio is the ratio of the length of a column and the least radius of gyration of its cross section.
Value of Cc - Value of Cc is the value of Cc used in calculating allowable compression stress.
Minimum Specified Yield Stress of Steel - (Measured in Pascal) - Minimum Specified Yield Stress of Steel is the maximum stress that can be applied before it begins to change shape permanently.

STEP 1: Convert Input(s) to Base Unit

Slenderness Ratio: 0.5 --> No Conversion Required
Value of Cc: 0.75 --> No Conversion Required
Minimum Specified Yield Stress of Steel: 40 Megapascal --> 40000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_a = (1-((λ^2)/(2*C_c^2)))/((5/3)+(3*λ/(8*C_c))-((λ^3)/(8*(C_c^3))))*F_y --> (1-((0.5^2)/(2*0.75^2)))/((5/3)+(3*0.5/(8*0.75))-((0.5^3)/(8*(0.75^3))))*40000000

Evaluating ... ...

F_a = 16551724.137931

STEP 3: Convert Result to Output's Unit

16551724.137931 Pascal -->16.551724137931 Megapascal (Check conversion here)

FINAL ANSWER

16.551724137931 ≈ 16.55172 Megapascal <-- Allowable Compression Stress

What is Allowable Compression Stress?

The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material.

Define Slenderness Ratio and it's purpose.

It is defined as the effective length of the column and the least radius of gyration, the latter defined by the area of the cross-section of the column and is the second moment of the area of the cross-section.
It is used extensively for finding out the design load as well as in classifying various columns in short/intermediate/long. The slenderness ratio of a column gives an indication of buckling failure in the column. The more the slenderness ratio, more the tendency of a column to fail by buckling effect in that direction.
