How to Calculate Effective Length of Column According to Johnson's Parabolic Formula?
Effective Length of Column According to Johnson's Parabolic Formula calculator uses Effective Column Length = (Compressive Yield Stress-(Critical Load On Column/Column Cross Sectional Area))/(Johnson's formula constant*(1/Least Radius of Gyration Column)) to calculate the Effective Column Length, The Effective length of column according to Johnson's parabolic formula formula is defined as the distance between successive inflection points or points of zero moment. Effective Column Length is denoted by Leff symbol.
How to calculate Effective Length of Column According to Johnson's Parabolic Formula using this online calculator? To use this online calculator for Effective Length of Column According to Johnson's Parabolic Formula, enter Compressive Yield Stress (σc), Critical Load On Column (P), Column Cross Sectional Area (Asectional), Johnson's formula constant (r) & Least Radius of Gyration Column (rleast) and hit the calculate button. Here is how the Effective Length of Column According to Johnson's Parabolic Formula calculation can be explained with given input values -> 3.3E+6 = (420-(5/1.4))/(6*(1/0.04702)).
