Column Base plate PROBLEM 1.10-14
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? Based upon your result, select a thickness for the column, (Select a thickness that is an even integer, such as 10, 1 14,.. ., in units of millimeters.)
(b) If the allowable bearing stress on the concrete pedestal is 15 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.
