Question
DAS (9e) Problem 10.6, add a question (c), what is
the depth Df for a 50 percent compensated
foundation.
10.6 It is proposed to build an 8 story building with a footprint
of 15 m x 20 m, resting on a mat foundation of the same
dimensions, in a saturated clay where c, 50 kN/m²,
y= 19.0 kN/m. Assume approximately 15 kN/m per floor
for the live and dead loads.
a. At what depth would you place the mat to make this a
fully compensated foundation?
b. What should be the factor of safety if the mat is placed at
3.0 m depth?
