Legacy data from the NEES cyberinfrastructure available in DesignSafe continues to prove useful for current NHERI researchers, including those seeking to validate new computational modeling frameworks. Researchers out of Penn State’s Institute for Computer and Data Sciences (Amir et al. 2020) reused experimental data on buckling at connections in steel structures from “Ultra-Low Cycle Fatigue and Fracture in Steel Structures” (Kanvinde et al. 2005) to validate one component of their hysteretic beam finite-element model. This model is incredibly versatile and can accommodate a variety of structural responses with diverse parameters and structural components. The researchers were able to recover all of the documentation and experimental information from the published dataset that they needed to simulate the experiment with their model, contributing to the demonstration of the broad validation of their model.
