The outside diameter of the steel pipe shown is 220 mm and its wall thickness is 6.0 mm. The upper bearing plate has the same width as the reinforced concrete beam it supports. The total load on the column by the reinforced concrete beam is 550 kN. Determine a. The average bearing stress between the pipe column and the upper steel bearing plates. b. The length L of the rectangular upper bearing plate if its width is 275 mm. and the average bearing stress between the steel plate and the reinforced concrete beam is not to exceed 6.2 MPa. c. The dimension a of the square lower bearing plate if the average bearing stress between the lower bearing plate and the concrete slab is not to exceed 6.2 MPa
