Structural Extreme Events Reconnaissance (StEER): Data to Knowledge Framework for Coordinated Reconnaissance following Natural Hazard Events

地震、飓风和龙卷风等自然灾害事件可能夺走不可替代的生命，给全国各地的社区造成数十亿美元的损失，对美国经济以及美国公民的安全和福祉造成连锁影响。不幸的是，这些损失只会越来越多。减少灾害造成的伤亡严重依赖于工程师系统地记录灾害对建筑环境的影响，并确保由此产生的知识迅速为新的监管政策和施工实践提供信息，指导更具弹性的恢复和重建。这一奖项将扩大结构性极端事件侦察(STEER)网络在这些从自然灾害中吸取教训的努力中的作用。该项目将简化网络的核心运营，支持志愿者工程师收集和处理有价值的灾后数据。同时，该项目将制定新的议定书，以便更有效地收集和处理数据以及向研究、政策和实践方面的支持者传播知识。这些方案将扩大包括本科生在内的研究界的参与，同时建设他们获得高质量法医数据的能力。研究界将进一步受益于由此产生的科学计划，该计划确保灾后观察为未来的研究提供信息，并将其转化为政策和实践。通过更有效地利用机会，不仅学习灾害研究中获得的知识，而且采取行动，该项目将帮助社区变得更具复原力和可持续性。该项目将有助于国家科学基金会(NSF)在国家减少地震灾害计划(NEHRP)和国家减少风暴影响计划(NWIRP)中发挥作用。该项目将开发新的协议，通过六个相互关联的目标的输出来提高转向网络的效率，首先是：(1)分层的区域数据收集模型，以便更灵活地进行实地反应；(2)统一各种危害和建筑类型的结构评估的工作流程；(3)自动数据收集和综合的新能力；以及(4)损害量化计划，提供与既定评级系统兼容的更客观的业绩评估。这四个目标的产出将增强网络的核心操作，以减少数据收集/处理需求、提高效率并减少延迟。这反过来将使该网络的成员能够将更多的精力用于深入的法医评估，将这些知识提供给新的传播渠道，该渠道是通过增加一个以选民为重点的侦察和通信枢纽而形成的。这与(6)观测驱动的科学规划相结合，将网络的发现与研究和技术转移机会联系起来。总而言之，这将导致一个更加连贯的自然灾害工程研究议程，并最终将有助于将下一代缓解战略转化为实践。项目数据将被存档，并在国家科学基金会支持的自然灾害工程研究基础设施(https://www.DesignSafe-ci.org).This)数据库中公开提供(NSF的裁决反映了国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Natural hazard events, such as earthquakes, hurricanes, and tornadoes, can claim irreplaceable lives and cause billions of dollars in damage to communities nationwide, with cascading impacts on the U.S. economy as well as the security and well-being of its citizenry. Unfortunately, these losses are only mounting. Reducing the toll of disasters depends critically upon engineers systematically documenting hazard impacts on the built environment and ensuring the resulting knowledge swiftly informs new regulatory policies and construction practices guiding more resilient recovery and rebuilding. This award will expand the role of the Structural Extreme Events Reconnaissance (StEER) Network in these efforts to learn from natural disasters. This project will streamline the network’s core operations, supporting volunteer engineers as they collect and process valuable post-disaster data. In parallel, this project will develop new protocols for more efficient data collection and processing as well as knowledge dissemination to constituencies in research, policy, and practice. These protocols will broaden the participation of the research community, including undergraduate students, while building their capacity for high-quality forensic data. The research community will further benefit from the resulting Science Plan that ensures post-disaster observations inform future research and its translation into policy and practice. By more effectively utilizing the opportunity to not only learn but act upon the knowledge gained in the study of disasters, this project will help communities to become more resilient and sustainable. This project will contribute to the National Science Foundation (NSF) roles in the National Earthquake Hazards Reduction Program (NEHRP) and the National Windstorm Impact Reduction Program (NWIRP). This project will develop new protocols that enhance the StEER network’s efficiency, achieved through the outputs of six interconnected objectives, beginning with: (1) a tiered, regional data collection model for more agile field responses, (2) a workflow that unifies structural assessments across hazards and building typologies, (3) new capacities for automated data collection and synthesis, and (4) a damage quantification scheme offering more objective evaluations of performance compatible with established rating systems. Outputs of these four objectives will enhance the network’s core operations to lessen data collection/processing demands, increase efficiency, and reduce latency. This in turn will enable the network’s members to direct more energy toward in-depth forensic evaluations, feeding this learning into new dissemination conduits, formed through the addition of (5) a constituent-focused reconnaissance engagement and communications hub. This is coupled with (6) observation-driven science planning that links the network’s findings to research and technology transfer opportunities. In total, this will result in a more coherent natural hazards engineering research agenda and ultimately will help translate next-generation mitigation strategies into practice. Project data will be archived and made publicly available in the NSF-supported Natural Hazards Engineering Research Infrastructure (NHERI) Data Depot (https://www.DesignSafe-ci.org).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
