Last month, I gave a webinar through the Lehigh EF Seminar Series on the higher-mode force and acceleration demands in seismic-force resisting systems employing strongback spines. The presentation discusses the evolution of the strongback, from its initial days as auxiliary outcome of a study on vintage braced frames, to its current iteration with force-limiting connections…

This post is very belated. In August, I gave a webinar through MECHS, a research coordination network funded by the National Science Foundation, on the potential use of real-time hybrid simulation for wave-structure interaction problems. See the webinar below. The website for MECHS can be found here: https://mechs.designsafe-ci.org/

Although my background is in earthquake engineering, I’ve recently been fascinated by wave-structure interaction problems. From a structural perspective, we are often focused on deformations due to external loading on the structure. In contrast, fluid mechanics is often focused on the effects of boundary conditions on the fluid flow. In some situations, the solid and…
