This material is based upon work supported by the National Science Foundation (NSF) under Grant No. CMMI-0830331 through the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES). The “Seismic Performance Assessment in Dense Urban Environments: Soil-Structure Interaction on the Scale of a City Block” project is a collaborative effort that includes the University of California, Berkeley (lead institution), University of Buffalo-SUNY, University of California, Davis, University of California, San Diego, California Polytechnic State University, San Luis Obispo, and the Consortium of Universities for Research in Earthquake Engineering. This project utilizes the NEES equipment site at the University of California, Davis. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the NSF.

This data report describes the fourth centrifuge test in a sequence of six tests designed with the overarching goal of developing an understanding of soil-structure interaction (SSI) in dense urban environments — often called structure-soil-structure interaction (SSSI). NWT01, also known internally as Test-4, was preceded by HBM02 (Test-1), HBM03 (Test-2), and HBM04 (Test-3). For interested parties, data reports are available for Test-1, Test-2, and Test-3 (Mason et al., 2010a,b,c) through the UC Davis Center for Geotechnical Modeling (, as well as through NEESHub (
