Example 16: Elastic square raft on Isotropic elastic half-space soil
medium
Description of the problem
To verify the mathematical model of
ELPLA
for elastic raft, the results of an elastic raft
at different relative stiffness obtained by other analytical
solutions from Stark/
Majer
(1988) and
Borowicka (1939) are
compared with those obtained by
ELPLA.
A rectangular raft with sides 12 [m] and 6 [m], rests on an
isotropic elastic half-space soil medium is chosen and subdivided into 12 * 12 elements as
shown in Figure 23. The elastic properties of the raft and the soil are
Es
= 10 000 [kN/m ],
Eb
= 2.6 *10 [kN/m ], νs= 0 [-], νb= 0.15 [-]. The raft carries a uniform load of 100 [kN/m2].
