(a)
Divide the rec tan gle into 4 parts
b = ; = 4.5
Зт
4.5 = 0.75
m =
Z.
6.
= = 0.5

n =
U sin g graph
1, (т, п) — 0. 10685
so,
q = Q (4 × I,) = 325 (4 × 0. 10685)
138. 905 kPa

The 6m x 9m rectangular foundation shown cariies a uniform load of 325 kPa.
a. Compute for the net stress increase at point A. (138.905)
b. Compute for the net stress increase at point B. (85.28)
c. Determine the total vertical at point A if the underlying soil has a unit weight of 17.45
