(25 pts) Consider a square footing with dimensions of 4 feet by 4 feet in plan bearing at a depth of 2.5 feet. A column load "P" is applied to

the center of the foundation. The soil above the bearing elevation has a unit weight (y) of 115 pcf. The bearing soil has a unit weight of 118 pcf, an effective friction angle () of 20 deg, and an effective cohesion (c') of400 psf. a) (15 pts) What is the allowable bearing capacity (in psf) for this foundation? b) (10 pts) What is the magnitude of the allowable design load (P, in kips) that can beapplied to the foundation? b) (10 pts) What is the magnitude of the allowable design load (P, in kips) that can beapplied to the foundation?
