This paper presents a fully-coupled non-linear numerical modelling approach for the prediction of the Lotung Large-Scale Seismic Test (LSST) site free-field response during the recorded event of May 1986. An advanced kinematic hardening soil model is calibrated using resonant column data and cross-hole measurements available at the LSST site. The two horizontal components of the input motion are applied separately at bedrock level. The acceleration time histories predicted at different depths are compared with the down-hole motions recorded in-situ, indicating a very good agreement with the array data in terms of peak ground acceleration and frequency content.
