Developing and testing a seismic-resistant family of self-centering (SC) steel frame systems with the potential to safely withstand the currently accepted design basis earthquake (DBE) for buildings without damage.
Using WTI’s INERTIA™ test software and National Instruments hardware to create a data acquisition and control system for control of the servo-hydraulics, data collection, and high-speed model execution in order to investigate the seismic behavior of large-scale structural components, structural sub assemblages, and super assemblages (systems).
“I’ve been working in the field of data acquisition and control for over 25 years. INERTIA is the only control package that offers this level of customization. The straightforward programming methodology, combined with the ability to completely customize your control application, makes INERTIA a perfect fit for the research environment.”

Lehigh University is home to the largest structural engineering lab in the Americas. As a member of the US National Science Foundation’s Network for Earthquake Engineering Simulation (NEES), Lehigh University uses their Advanced Technology for Large Structural Systems (ATLSS) research center to investigate the seismic behavior of large-scale structural components. One of their projects involves the development and testing of SC steel frame systems, an innovative technology that is designed to avoid structural damage and inelastic deformations during earthquakes, unlike conventional, earthquake-resistant steel frame systems.
