The “penalty” of the heavily loaded foundation is to sustain substantial additional
vertical settlements,

Particularly significant, although somewhat coincidental, is the very small residual
rotationinbothcases.Thisisduetothelargelysymmetricnatureoftheexcitation,as
a result of which the heavily loaded foundation develops “left” and “right” bearing-
capacity failure mechanisms. The resulting two-sided inelastic deformations lead to
