Problem 17.5 A column transfers a factored load of 700 kips to a 9-ft square footing shown
in Figure P17.5, resulting in a factored uniform soil pressure of 8640 psf. Design the footing
reinforcement using strut-and-tie methods. Material strengths are
16.1. A cantilever retaining wall is to be designed with geometry as indicated in Fig. P16.1 .
Backfill material will be well-drained gravel having unit weight w = 120 pcf, internal friction angle
' = 33 , and friction factor against the concrete bas
Notes regarding reinforcement details.
In the following problems, the reinforcement details are compressed to clarify the problem solutions. The
reinforcement details are noted by the line:
Reinforcement is shown by bar size. Thus a
