Critical buckling load
Problem statement
Calculate the maximum load that a pin-ended column made of 20 mm (3/4 in) steel plate (E = 200 GPa and σy = 210 MPa) can support. The column was braced about its weak axis and was designed with a factor of safety of 2.5.
Figure data: 8 m column braced 3 m from the base; built-up section of 300, 280, 160 and 180 mm plates.
Concepts: pin-ended column, bracing, weak axis, Euler formula, factor of safety
