How to Calculate Critical Elastic Moment?
Critical Elastic Moment calculator uses Critical Elastic Moment = ((Moment Gradient Factor*pi)/Unbraced Length of Member)*sqrt(((Elastic Modulus of Steel*Y Axis Moment of Inertia*Shear Modulus*Torsional Constant)+(Y Axis Moment of Inertia*Warping Constant*((pi*Elastic Modulus of Steel)/(Unbraced Length of Member)^2)))) to calculate the Critical Elastic Moment, The Critical Elastic Moment formula is defined as the methods given in design codes for determining the slenderness of a section. The elastic critical moment (Mcr) is similar to the Euler (flexural) buckling of a strut in that it defines a buckling load. Critical Elastic Moment is denoted by Mcr symbol.
How to calculate Critical Elastic Moment using this online calculator? To use this online calculator for Critical Elastic Moment, enter Moment Gradient Factor (Cb), Unbraced Length of Member (L), Elastic Modulus of Steel (E), Y Axis Moment of Inertia (Iy), Shear Modulus (G), Torsional Constant (J) & Warping Constant (Cw) and hit the calculate button. Here is how the Critical Elastic Moment calculation can be explained with given input values -> 6.791907 = ((1.96*pi)/12)*sqrt(((200000000000*5E-06*80000000000*21.9)+(5E-06*0.2*((pi*200000000000)/(12)^2)))).
