The primary objectives of this project are two folds: (1) to demonstrate how researchers from multiple universities can conduct collaborative research using a network of experimental facilities distributed around the country and utilizing the advanced NEES information technology tools to collect, communicate, and archive large volumes of data, and (2) to conduct high quality studies of soil-foundation-bridge structure systems. The project involves field testing, centrifuge testing, structural component studies, and shake table testing of a two-span bridge frame. A strong educational component is embedded throughout all the phases of the study. The overall project is being managed by researchers from the University of Texas, Austin. Other investigators are from the University of California, Berkeley and Davis, Kansas University, University of Michigan, University of Nevada, Reno, Purdue University, San Jose State University, and the University of Washington.
