14. In typical floor support, a short timber post is capped with a steel channel to provide a larger bearing area for the joists. The joists are 6"x12" rough cut. The steel base plate is provided to increase the bearing area on the concrete footing. The load transmitted from each floor is 6.0k. (10 pts) -FLOOR JOISTS- STEEL CHANNEL CAP WOOD POST STEEL BASE CONCRETE FOOTING (a) 4 pts: Find the minimum channel length required to support the joists if the maximum allowable bearing stress perpendicular to the grain is 500 psi. (b) 6 pts: Find the base plate size required if the allowable bearing on concrete is 500 psi.
