Welcome to the RTMD Facility

The Lehigh University RTMD facility located in the ATLSS Research Center (IMBT Laboratory) allowed 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 was achieved through the combined use of dynamic actuators, reaction wall, strong floor and high performance computing. This facility as also designed to support multi-site distributed hybrid testing methods where the substructures involved were at different geographic locations.

Testing of NEESR-CR: Post-Tensioned Coupled Shear Wall Systems at Lehigh University Friday, November 10, 2014

This NEESR project entitled NEESR-CR: Post-Tensioned Coupled Shear Wall Systems (PIs: Yahya Kurama, University of Notre Dame, and Michael McGinnis, University of Texas at Tyler) is conducting large-scale experiments and accompanying numerical simulations of post-tensioned coupled shear wall structures at the Real-time Multi-directional (RTMD) Earthquake Simulation Facility, the Lehigh NEES Equipment Site. The goal of this NEESR project is to develop a new type of earthquake-resistant reinforced concrete (RC) coupled wall system with significant performance and economic benefits over conventional coupled wall systems.

Engineers re-create tsunami debris impacts to measure their force

In a tsunami, devastation is created by far more than the wave itself. Debris that hits homes and other structures plays a huge role in a tsunami’s destructive power. But until now, engineers could only estimate the forces at work when debris, such as a floating telephone pole, hits a house. With support from the […]
