Research Experiences for Undergraduates (REU), NHERI 2022: 3D Model of a Concentrically Braced Frame for Real-Time Hybrid Simulation

This project provides an in-depth study into how floor isolation systems (FISs) perform when subjected to floor accelerations from a 3D building model of a special concentrically steel braced frame (SCSBF) building during real-time hybrid simulation (RTHS). The project details the creation and study of a 3D model of a SCSBF building using HyCoM-3D, a 3D modeling software created for use at the NHERI Lehigh Experimental Facility. Data in this project can be reused to further assess how FISs behave when subjected to accelerations and their ability to isolate large nonstructural components of buildings and lessen their damage when subjected to different accelerations due to different building configurations. This project is unique because it considers the multi-directional response of a FIS subjected to floor motions simulated from a 3D, nonlinear model of a SCSBF building. The main audience is researchers and professionals interested in learning more about how FISs can limit damage to nonstructural building components.
