The following model applies to columns simply supported at each end (). Firstly, we will put attention to the fact there are no reactions in the hinged ends, so we also have no shear force in any cross-section of the column. The reason for no reactions can be obtained from symmetry (so the reactions should be in the same direction) and from moment equilibrium (so the reactions should be … WebM= EIw 00, the local equilibrium equation for the column self buckling becomes EI d4w dx4 + d dx q(l x) dw dx = 0 (10.6) Integrating once, we get EI d3w dx3 + q(l x)dw= 0 (10.7) The integration constant is zero because the shear force vanishes at the free end x= l.
