・PE=π^2*E*I/(K*l)^2.In the case that ignore Shear Deformation.
・Pcr=PE/(1+PE/(G*κ*A)).In the case that considering Shear Deformation.
・A:Cross sectional area of column.
・G:Elastic shear modulus.G=E/(2*(1+γ)).γ:Poisson's ratio.
・κ:Shear Coefficient.κ=∫1/(k^2/A)・dA. k=τ*A/Q.τ:Shear stress.
-Shear Coefficient is 『The ratio of the average shear strain on a section to the shear strain at the centroid』(Reference:『The Shear Coefficients in Timoshenko's Beam Theory』.)
