A steel column of length L is 16 feet and a rectangular crosssection a is 2 inch and b is 4 inches. The column has a fixed end at B and supports a centric load at A. Two smooth and rounded fixed plates restrain end A from moving in one of the vertical planes of symmetry but allow it to move in the other plane. The steel has yield strength of 36 ksi. Use a modulus E = 29 x 106 psi and a factor of safety F.S.2.0. Determine: 17 A B L y (1) Recognize the boundary conditions in xy plane and in xz plane. (2) Effective length of the column in xy plane and in xz plane. (3) Critical load (Euler formula) in xy plane and in xz plane. (4) Based on the calculation result in (3), in which plane is the column easier to buckle? (5) the maximum force P that can be applied without causing the column to either buckle or yield. (Need to consider the F.S.) A steel column of length L is 16 feet and a rectangular crosssection a is 2 inch and b is 4 inches. The column has a fixed end at B and supports a centric load at A.
