5.3 A short steel column supports an axial compressive load of 120,000# and is welded to a steel base plate resting on a concrete footing. a) Compute the area of steel por b. Determine the size of the base plate (square) required if the allowable bearing on concrete is 450 psi. c. Calculate the required size of footing (square) if the allowable soil pressure is equal to 3,000 psf. Neglect weights of column, base plate, and footing.
