The steel pipe column shown in the following Figure has an outside diameter of 8 in. and a wall thickness of 0.25 in. The timber beam is 10.75 in. wide, and the upper plate has the same width. The load imposed on the column by the timber beam is 70 kips in the direction of gravity. Determine: a. The average bearing stress at the surfaces between the pipe column and the upper and lower steel bearing plates. b. The length L of the rectangular upper bearing plate if its width is 10.75 in. and the average bearing stress between the steel plate and the wood beam is not to exceed 500 psi. 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 800 psi.

![The steel pipe column shown in the following Figure has an outside diameter of 8 in.
and a wall thickness of 0.25 in. The timber beam is 10.75 in. wide, and the upper plate
has the same width. The load imposed on the column by the timber beam is 70 kips in
the direction of gravity. Determine:
a. The average bearing stress at the surfaces between the pipe column and the
upper and lower steel bearing plates.
b. The length L of the rectangular upper bearing plate if its width is 10.75 in. and
the average bearing stress between the steel plate and the wood beam is not to
exceed 500 psi.
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 800 psi.
d. The dimensions of the concrete pad footing if the soils below it are not to exceed
a bearing pressure of 4 psi.
