Example 12: Simple assumption model for irregular raft
Description of the problem
To verify the simple assumption model of
ELPLA,
the contact pressure distribution of an irregular foundation obtained by
Bowles
(1977) (Example 9-6, page 265) is compared with
that obtained by
ELPLA.
A square foundation has 10 [m] side is chosen. The foundation is subjected to a column load of 540 [kN] at the center. It is required to determine the
distribution of the contact pressure when the corner is notched as shown in Figure 16.
The notch has
the following properties:
Area A
= 4.5 [m2]
Center of gravity from
o
in x-direction
x!
= 3.5 [m]
Center of gravity from
o
in y-direction
y!
= 4.25 [m]
