Question 1
A horizontal beam AB with a pin-support at A and an allowable clockwise moment of M =
60 kNm at Point B. At C the beam is supported by pinned-end column CD of length L, the column
is laterally restrained at 0.6L from the base at D only in the horizontal direction of the plane of
the frame (i.e. plane of the paper). The column is a steel (E = 200 GPa) pipe with a length
L = 2.5 m and an outside diameter of 100 mm. The factor of safety with respect to buckling is
n = 2.5. Let d=L/2. Determine the required wall thickness t for the pipe section CD.
