<p>Based on conceptual frameworks of soil behavior and published experimental data related to stress and strain thresholds, alternative cyclic strain regime divisions and the cyclic strain thresholds that represent the change in soil behavior are proposed. ...

<p>The prescribed motion to be used as base excitation for shear wave propagation studies in soils is not well defined in the literature. This paper utilizes two methods to investigate the concept of utilizing one-half the rock surface velocity as the incident ...
