Abstract
Tests were executed to analyze the behavior of disturbed foundation stiffness. Test results reveal a causal link between stiffness hysteresis loops and applied deformation amplitude. By manipulating the applied deformation amplitude, the size and position of stiffness hysteresis loops is plausible to control. The initial stiffness curve can be erased (disturbed) and reset afterwards. Also, cyclic stiffness curves of various size can be stabilized and repositioned. Such behavior is not predicted or accounted for by conventional models.
