A continuous strip footing is to be located concentrically under a 12 in. wall that delivers service loads D = 25,000 lb/ft and L = 15,000 lb/ft to the top of the footing. The bottom of the footing will be 4 ft below the final ground surface. The soil has a density of 120 pcf and allowable bearing capacity of 8000 psf. Material strengths are f = 3000 psi and f, = 60,000 psi. Find (a) the required width of the footing, (b) the required effective and total depths, based on shear, and (c) the required flexural steel area.

Transcribed Image Text:A continuous strip footing is to be located concentrically under a 12 in. wall
that delivers service loads D = 25,000 lb/ft and L = 15,000 lb/ft to the top of
the footing. The bottom of the footing will be 4 ft below the final ground
surface. The soil has a density of 120 pcf and allowable bearing capacity of
8000 psf. Material strengths are f = 3000 psi and f, = 60,000 psi. Find (a) the
required width of the footing, (b) the required effective and total depths, based
on shear, and (c) the required flexural steel area.
