Skin Friction for footing

Skin Friction for footing

(OP)
Would it be right to reference end bearing and skin friction for the design of footing which is 3' in dia and 15' deep?

RE: Skin Friction for footing

Sometimes, depends on the materials and the purpose of the foundation.

(OP)
It is the footing for the flagpost. The footing is 4000 psi concrete.

RE: Skin Friction for footing

Flagpoles usually don't cause much in the way of vertical loading, so you can probably take it all in end bearing.  Lateral loading causes bending of the pier, and has to be resisted by passive soil pressure.
