1.A strip footing carries a load 17709 lbs per foot of
length. The footing has a width of 1.1 ft. Determine
the increase in vertical stress directly below the center of the
footing at a depth of 4.4 ft. Provide your answer
in psf, to 2 decimal place.
2.The site for a commercial building project has the surface
elevation lowered by 1.41 m to improve area grading for the
building access, parking and drainage. The unit weight of the
soil removed was 19.0 kN/m3. Foundations for the
building will be constructed at the level of the new ground surface
elevation. Each foundation is 1.5 m by 1.5 m square and
imposes a bearing pressure of 314 kPa. Using the 2:1
approximation method determine the net increase in stress (kPa) at
a depth of 1.0 m below the footing. Provide your answer to 2
decimal places.
