Fluid structure interaction for cascading seismic and tsunami events using real-time hybrid simulation
While real-time hybrid simulation has been utilized for structures subjected to seismic events for decades, its use in fluid-structure interaction problems is still a novel endeavor. Gathering data for cascading seismic and tsunami events is difficult due to space constraints in existing experimental facilities, complications regarding the application of scaling laws for both the fluid…

Mitigating computational bottlenecks using graphics processors
I have become fascinated by the intersection of computer hardware and the fidelity of our numerical analyses. For example, graphics processors (GPUs), real-time computer chips used for gaming and machine learning, could be leveraged to accelerate our computational models, enabling faster and higher-fidelity simulations. In using GPU-based computing, the governing equations of motion would remain…

Musings on the evolution of the strongback
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…
