A 10 m high 150UC30 steel column is fixed at its base and restrained to move laterally in the x direction at the top and at mid-height. Determine the allowable eccentric force P that can be applied without causing the column to either buckle or yield. Adopt a safety factor of 2 against buckling and yielding. Hint: You may choose to use a computer program to help solve the arising iterative equation. Alternatively, you may choose to not solve the equation at all and check the criticality of a requirement by simple substitution.
