Abstract

Liquefaction induced ground failures during seismic events have been of major concern to the engineering community. Laboratory, full-scale, and centrifuge experimentation has provided valuable insights on the mechanics and propagation of liquefaction. Concurrently, advances in the computational field have led to refined numerical tools to simulate the liquefaction phenomenon. In an effort to better evaluate the modeling capabilities, the Liquefaction Experiments and Analysis Project (LEAP) aims at providing numerical modelers with high quality experimental data that can be used in a series of prediction exercises. For this purpose, in early 2015 several centrifuge tests were conducted at different facilities all over the world and were followed by numerical simulations. This paper presents the centrifuge test that was conducted at the Center for Earthquake Engineering Simulation at Rensselaer Polytechnic Institute and discusses the modeling techniques that were employed in order to gain a variety of information on the soil response.
