Computer Simulation of Earthquake Effects

New techniques such as the shear wave velocity techniques, electrical methods, and ground penetrating radar have potential for providing new, reliable information. Results presented in these papers collectively demonstrate that these new techniques should be given serious consideration for predicting the liquefaction behavior of saturated sands during earthquakes. This proceeding presents nondestructive site characterization and property evaluation, constitutive modeling and numerical procedures, and applications. The papers cover: details on the use of an electrical technique for evaluating in situ properties; the use of ground penetrating radar for predicting changes in soil density during soil liquefaction; how shear wave velocities measured in situ are capable of predicting the liquefaction potential; the constitutive modeling of flow liquefaction and cyclic mobility in detail; soil-pile structure interaction in liquefiable soils; and non-destructive electrical in situ site characterization to quantify the initial state parameters and constitutive model constants representative of the site for use in verified numerical procedures.
