|P Column P Base plate -D-
A steel column of hollow circular cross section
is supported on a circular, steel base plate and
a concrete pedestal (see figure). The column has an
outside diameter d = 250 mm and supports a load
P = 750 kN.
(a) If the allowable stress in the column is 55 MPa,
what is the minimum required thickness t? Based
upon your result, select a thickness for the column.
(Select a thickness that is an even integer,
such as 10, 12, 14, . . ., in units of millimeters.)
(b) If the allowable bearing stress on the concrete
pedestal is 11.5 MPa, what is the minimum
required diameter D of the base plate if it is
designed for the allowable load Pallow that the
column with the selected thickness can support?
