Engineers re-create tsunami debris impacts to measure their force
The researchers' ultimate goal is to improve building designs so structures are built to better withstand the forces generated from tsunami debris

Welcome to NEES@Lehigh
The US National Science Foundation has established the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) as a national, networked collaboration of geographically-distributed, shared-use experimental research equipment sites. Each site has telepresence and teleoperation capabilities, computer models and physical test specimens, which will transform the environment for earthquake engineering. NEES@Lehigh is an equipment site specializing in real-time multi-directional (RTMD) testing for earthquake simulation of large-scale structural systems.
The Lehigh University RTMD facility located in the ATLSS Research Center (IMBT Laboratory) allows for real-time multi-directional hybrid seismic testing, combined with real-time analytical simulations, to investigate the seismic behavior of large-scale structural components, structural sub assemblages, and super assemblages (systems). This is achieved through the combined use of dynamic actuators, reaction wall, strong floor and high performance computing. This facility is also designed to support multi-site distributed hybrid testing methods where the substructures involved are at different geographic locations connected by the NEES network.
