The NEES Data Model in Support of Earthquake Engineering Research

Abstract eng:
The George E Brown Jr. Network for Earthquake Engineering Simulation (NEES) is a shared national network of 15 experimental facilities, collaborative tools, a centralized data repository, and earthquake simulation software, all linked together to enable engineers to develop better and more cost-effective ways of mitigating earthquake damage. To support data organization, archiving and dissemination resulting from NEES related research, the NEES Cyberinfrastructure Center (NEESit) has developed an abstract data model for earthquake engineering projects and an implementation of that data model through the NEEScentral Data Repository application. The NEES Data Model represents classes of entities and relationships to provide essential data for reproducing experimental and computational simulation results. It is based on a hierarchical structure, consisting of Projects, Experiments, Trials and Repetitions, that collects highly detailed information from each experiment or computational simulation in order to be able to reproduce the research. The NEEScentral Data Repository provides data management infrastructure to shorten the gap between research and practice through long-term preservation and sharing of data. The ultimate goal is to provide access to different types of experimental and computational data to promote and facilitate collaborative and interactive processes required to address the complex nature of seismic events and their physical and societal impacts, ultimately reducing vulnerabilities from earthquakes. This paper describes the details of the NEES data model and presents an overview of the NEEScentral data repository application. Future directions for the NEES Data Model are provided.
