Advances in the Art of Testing Soils Under Cyclic Conditions

Abstract

The session on “Advances in the Art of Testing Soils under Cyclic Loading Conditions” was organized by the Soil Dynamics committee of the American Society of Civil Engineers in an endeavor to evaluate the state of practice governing testing equipment and methodology, and behavioral analysis of materials. The topics included centrifuge modeling of soils, torsional triaxial and direct shear devices and their use with hollow cylindrical soil specimens, applications of the constant volume cyclic simple shear device, monotonic and cyclic loading behavior for triaxial stress conditions, effects of irregular and multi-directional load application, evaluation of liquefaction flow failure during earthquakes, influence of testing techniques on soil properties in a cyclic triaxial apparatus, evaluation of shear wave velocity and shear modulus using cubic soil samples or bender elements, and mathematical modeling of nonlinear behavior in a resonant column test.
