What is End Fixity Coefficient?
The end fixity coefficient is defined as the ratio of the moment at one end to the moment at the same end when both the ends are ideally fixed.
c=2, both ends pivoted;
c=2.86, one pivoted, other fixed;
c=1.25 to 1.50,Restraining bulkhead partially fixed;
c=4, both ends fixed;
c=1 one fixed, one free.
How to Calculate Allowable Compressive Stress for Aluminium Columns?
Allowable Compressive Stress for Aluminium Columns calculator uses Allowable Column Compressive Stress = (End Fixity Coefficient*pi^2*Modulus of Elasticity)/(Effective Length of Column/Radius of Gyration of Column)^2 to calculate the Allowable Column Compressive Stress, The Allowable Compressive Stress for Aluminium Columns formula is defined as the maximum stress (tensile, compressive or bending) that can be applied on a structural material such as Aluminium Columns without any deformation. Allowable Column Compressive Stress is denoted by Fe symbol.
How to calculate Allowable Compressive Stress for Aluminium Columns using this online calculator? To use this online calculator for Allowable Compressive Stress for Aluminium Columns, enter End Fixity Coefficient (c), Modulus of Elasticity (E), Effective Length of Column (L) & Radius of Gyration of Column (ρ) and hit the calculate button. Here is how the Allowable Compressive Stress for Aluminium Columns calculation can be explained with given input values -> 5.5E-5 = (4*pi^2*50000000)/(3/0.5)^2.
