A steel column of hollow circular cross section shown in Figure is supported on a circular steel base plate and concrete pedestal The column has outside diameter 220 mm and a wall thickness of 15 mm. It supports an axial load of 680 kN.a. Determine the bearing stress induced by the column to the base plate in MPa.b. If the allowable bearing stress on the pedestal is 10MPa, determine the required diameter of the base plate in mm.
Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown in the figure. One load of P=33P=33 kipskips is applied to the assembly at A, two loads of Q=30Q=30 kipskips are applied at B, and two loads of R=35R=35 kipskips are applied at C. The normal stress magnitude in aluminum rod (1) must be limited to 1717 ksiksi. The normal stress magnitude in steel rod (2) must be limited to 3030 ksiksi.
