Allowable Stress when Slenderness Ratio is Less than Cc Solution

STEP 0: Pre-Calculation Summary
Formula Used
Allowable Stresses in Columns = (Yield Strength of Steel/2.12)*(1-((Effective Length Factor*Length of Bridge Column/Radius of Gyration)^2)/(2*Slenderness Ratio Cc^2))
Fa = (fy/2.12)*(1-((k*L/r)^2)/(2*Cc^2))
This formula uses 6 Variables
Variables Used
Allowable Stresses in Columns - (Measured in Megapascal) - The allowable stresses in columns is the material failure stress (a property of the material) divided by a factor of safety greater than one.
Yield Strength of Steel - (Measured in Megapascal) - Yield strength of steel is the level of stress that corresponds to the yield point.
Effective Length Factor - Effective Length Factor is the factor used for the members in the frame. It depends on the ratio of compression member stiffness to the end restraint stiffness.
Length of Bridge Column - (Measured in Meter) - Length of bridge column is the distance between the two floors or the distance between the column's fixed points (fixed or pinned), where all its movement is constrained in all directions.
Radius of Gyration - (Measured in Meter) - Radius of Gyration is used to compare how various structural shapes will behave under compression along an axis. It is used to predict buckling in a compression member or beam.
Slenderness Ratio Cc - Slenderness Ratio Cc is the ratio that demarcates between inelastic member buckling from elastic member buckling.
STEP 1: Convert Input(s) to Base Unit
Yield Strength of Steel: 250 Megapascal --> 250 Megapascal No Conversion Required
Effective Length Factor: 0.5 --> No Conversion Required
Length of Bridge Column: 3 Meter --> 3 Meter No Conversion Required
Radius of Gyration: 15 Millimeter --> 0.015 Meter (Check conversion here)
Slenderness Ratio Cc: 200 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Fa = (fy/2.12)*(1-((k*L/r)^2)/(2*Cc^2)) --> (250/2.12)*(1-((0.5*3/0.015)^2)/(2*200^2))
Evaluating ... ...
Fa = 103.183962264151
STEP 3: Convert Result to Output's Unit
103183962.264151 Pascal -->103.183962264151 Megapascal (Check conversion here)
FINAL ANSWER
103.183962264151 103.184 Megapascal <-- Allowable Stresses in Columns

What is Allowable Stress in concentrically loaded columns?

The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material. The allowable stresses are generally defined by building codes, and for steel, and aluminum is a fraction of their yield stress (strength)
