Abstract
DesignSafe addresses the challenges of supporting integrative data-driven research in natural hazards engineering. It is an end-to-end data management, communications, and analysis platform where users collect, generate, analyze, curate, and publish large data sets from a variety of sources, including experiments, simulations, field research, and post-disaster reconnaissance. DesignSafe achieves key objectives through: (1) integration with high performance and cloud-computing resources to support the computational needs of the regional risk assessment community; (2) the possibility to curate and publish diverse data structures emphasizing relationships and understandability; and (3) facilitation of real time communications during natural hazards events and disasters for data and information sharing. The resultant services and tools shorten data cycles for resiliency evaluation, risk modeling validation, and forensic studies. This article illustrates salient features of the cyberinfrastructure. It summarizes its design principles, architecture, and functionalities. The focus is on case studies to show the impact of DesignSafe on the disaster risk community. The Next Generation Liquefaction project collects and standardizes case histories of earthquake-induced soil liquefaction into a relational database—DesignSafe—to permit users to interact with the data. Researchers can correlate in DesignSafe building dynamic characteristics based on data from building sensors, with observed damage based on ground motion measurements. Reconnaissance groups upload, curate, and publish wind, seismic, and coastal damage data they gather during field reconnaissance missions, so these datasets are available shortly after a disaster. As a part of the education and community outreach efforts of DesignSafe, training materials and collaboration space are also offered to the disaster risk management community.
Highlights
There is a variety of natural hazards, which includes meteorological hazards like hurricanes, tornadoes, thunderstorms, and downbursts; seismic hazards such as ground shaking and ground liquefaction; and hydrological hazards, for example storm surges, tsunamis, and inland floods
This article concludes by presenting some case studies, which illustrate the impact of DesignSafe on different segments of the disaster risk management community, and, by inviting discussion on steps forward, the ability of DesignSafe to harness the resources of the cyberinfrastructure for present and future needs
Diverse data sets from a range of sources must be integrated in models that are often increasingly complex and integrative across disciplines ranging from hazard sciences, engineering, and social sciences
Summary
There is a variety of natural hazards, which includes meteorological hazards like hurricanes, tornadoes, thunderstorms, and downbursts; seismic hazards such as ground shaking and ground liquefaction; and hydrological hazards, for example storm surges, tsunamis, and inland floods. For a holistic assessment of community resilience, disaster risk managers need to integrate different sources of expertise and data across the various thematic domains. This involves management and analysis of large multidisciplinary datasets that correspond to different kinds of natural hazards The purpose of NHERI is to integrate seven large natural hazards experimental facilities across the United States with simulation laboratories and disaster reconnaissance efforts, to enable researchers to explore and test ground-breaking concepts to protect homes, businesses, and infrastructure lifelines from earthquakes and windstorms. This article concludes by presenting some case studies, which illustrate the impact of DesignSafe on different segments of the disaster risk management community, and, by inviting discussion on steps forward, the ability of DesignSafe to harness the resources of the cyberinfrastructure for present and future needs
