Euler buckling end conditions

WebDetermine the allowable load using a factor of safety of 2.5 with respect to Euler buckling. The proportional limit of the steel is 275MPa.A long slender column ABC is pin-supported at the ends and compressed by an axial load P. Lateral support is provided at 4m 4m y yx x Ix=2220 cm4, Iy=727.2 cm4 and A=123 cm2 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 …
