Figure D-1: Steel Column Pedestal and Footing
Foundations for steel framed buildings generally consist of a reinforced concrete pad located at a suitable depth on a bearing stratum. The pad supports a stub column which has the column holding down bolts cast into it. The height of the stub column is such that the column base is located at the desired elevation.
Since steel framed buildings are comparatively light weight structures, the footing size is determined by the size of the adequate anchor required to prevent uplift due to wind. The size of footing should therefore be provided by the designer or supplier, and the horizontal restraint needed at the column bases must also be shown on the drawing.
Because of this, it is not possible to provide specific design guidelines for the footing, since the size of the footing is dependent upon the forces which would be generated by the wind. Experienced engineers would be required to carry out a wind analysis, the result of which would permit design of the footing to be undertaken.
