Tests of a rolling-pendulum base-isolation system were performed as part of NSF award CAREER: Mitigation of Seismic Risk to Critical Building Contents via Optimum Nonlinear 3D Isolation (PI- Scott Harvey, University of Oklahoma, award #1943917). The work involved multi-directional real-time hybrid simulations (RTHS) of a rolling pendulum system for seismically isolating equipment in mission-critical buildings.

We've been busy this summer creating our new real-time multi-directional shake table test bed! There's quite a bit of work left but this is exciting as it adds new 3DOF capabilities for researchers to use NHERI Lehigh for their experiments.
