Question

A W14x54 steel column rests on a concrete
pedestal. Column base plate is to be provided and
designed using the full capacity of the column for axial
load. The properties of the steel column are shown in the
table. Yield strength of the column and base plate is 248
MPa. For concrete; f’c = 21 MPa.

a. Determine the axial capacity of the column.
(LRFD)
b. Determine the smallest dimension of the square
base plate so that the allowable bearing for the
concrete support is not exceeded? (Increment of
5mm)
c. Determine the thickness of the base plate
