Testing Seismic Isolation with Real-time Hybrid Simulation

Testing Seismic Isolation with Real-time Hybrid Simulation

Author: Natural Hazards Engineering Research Infrastructure June 7, 2022 Duration: 10:38

University of Oklahoma earthquake engineer Scott Harvey is developing a base isolation system to protect valuable and sensitive contents inside buildings. He employed the shake table at the NHERI Lehigh University experimental facility to learn how his isolation system behaves under shaking. In his next experiments, Harvey will deploy the magic of real-time hybrid simulation (RTHS) to numerically simulate buildings with his physical device -- using NHERI Lehigh’s well-known RTHS capabilities.

The forces that shape our world aren't always gentle. Earthquakes, hurricanes, floods, and tornadoes are a reality of life on this planet, but the scale of their impact is something we can influence. DesignSafe Radio, from the Natural Hazards Engineering Research Infrastructure team, delves into the human ingenuity working to soften the blow of these events. This isn't just a theoretical discussion; it's a close look at the rigorous testing, data, and engineering research funded by the National Science Foundation that aims to protect communities. Each episode pulls back the curtain on how scientists and engineers are learning from past disasters to fortify our future. You'll hear conversations about the tools and methods transforming how we understand structural resilience, offering a tangible sense of how research translates into real-world safety. The goal is straightforward: to ensure the next natural hazard doesn't escalate into a catastrophe for families and neighborhoods. Tune into this podcast for a grounded perspective on the intersection of science, education, and practical solutions, where complex research is made accessible and the focus remains firmly on building a more durable society.
