Est = 200 GPa and Y = 250 MPa EXAMPLE : 2 (contd.) From table in Appendix B, column’s x-sectional area and moments of inertia are A = 5880 mm2, Ix = 45.8 106 mm4,and Iy = 15.4 106 mm4. By inspection, buckling will occur about the y-y axis.
WebEuler Buckling Theory is the classical theory presented in textbooks and classrooms. It begins simply by noting that the internal bending moment in a loaded and deformed column is −P y − P y where P P is the compressive load and y y is the column deflection. So insert −P y − P y in for M M in the beam bending equation, EI y′′ = M E ...
