ABSTRACT: This paper documents the development of a new combined triaxial simple shear (TxSS) apparatus. The TxSS system consists of a simple shear apparatus incorporated in a triaxial cell for the measurements of static and dynamic characteristics of soil samples. A general description as well as some applications and advantages of the TxSS systems over the traditional apparatus are given in this paper. The key application of TxSS is the evaluation of liquefaction potential of soil under regular or irregular excitations. Sample results in terms of static and dynamic characteristics obtained using the Tx SS device on different cohesive and cohesionless soil samples are presented to illustrate its capabilities, and they are successfully compared to those obtained using reliable design charts available in the literature as well as those from rigorous numerical analyses using the computer code FLAC. Keywords: Tx SS , DSS, triaxial, simple shear, liquefaction.
