ROCKING IMPEDANCE OF EMBEDDED STRIP FOUNDATIONS IN LAYERED SOIL

An extensive parametric study has been performed to investigate the influence of the following factors on the rocking impedance of a rigid strip foundation embedded in a viscoelastic layered soil: depth of embedment; thickness of the top soil layer; height of contact at the foundation sidewall-soil interface; and ratio of shear wave velocities of layers for a 2-layered soil profile. The study used an advanced algorithm of the boundary element method developed by incorporating isoparametric quadratic elements and a sophisticated self-adapting numerical integration scheme. The details of the study are described, and the results are discussed.
