CAREER: Integration of Steel Grain Bin Vulnerability and Rural Community Resilience for Multiple Hazards

该教师早期职业发展（CAREER）奖将促进对钢粮仓性能的理解，以及农业农村社区对自然灾害，特别是地震和风暴的适应能力。农村和农业社区的复原力通常落后于城市社区，部分原因是其独特的基础设施，该项目将采取综合研究和教育方法来提高其复原力。与钢粮仓性能相关的调查结果将直接翻译给制造商。一个综合的基础设施和农村社区复原力模型将使各个社区能够评估其复原力，并考虑到其独特的建筑环境。该教育计划将通过增加在大学一级追求和坚持工程学的农村学生人数，促进未来STEM劳动力的多样化和加强，目前城市和农村学生之间存在着巨大的差距。将开发一个公民科学考察平台，进一步让广大农村公民参与抗灾能力的研究和实践。该项目将有助于国家科学基金会（NSF）在国家地震灾害减少计划（NEHRP）和国家风暴影响减少计划（NWIRP）中的作用。该项目的总体目标是对钢粮仓的性能以及农业农村社区在遭受地震和直线风暴时的恢复力有一个基本的了解。为了实现这一目标，研究计划将包括两个主要的研究重点：钢粮仓脆弱性和社区复原力影响评估。钢粮仓的主要研究任务将包括钢粮仓的高保真数值建模，大规模地震和气动弹性测试，以及元模型的开发，以促进脆弱性分析，将危害强度与一系列粮仓的损坏概率相关联。与社区复原力有关的主要任务将包括制定一个农业社区复原力模型，该模型将在纵向结构和社区普查方面得到验证，并评价旨在提高复原力的缓解措施。本研究将使用美国国家科学基金会支持的自然灾害工程研究基础设施（NHERI）在佛罗里达国际大学的风墙设施进行气动弹性测试，并将在NHERI数据库（https：//www.example.com）中存档和公开提供项目数据www.DesignSafe-ci.org。本项目由土木基础设施工程（ECI）计划和刺激竞争研究的既定计划（EPSCoR）联合资助。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This Faculty Early Career Development (CAREER) award will advance understanding of the performance of steel grain bins and the resilience of agriculturally based rural communities to natural hazards, particularly earthquakes and windstorms. The resilience of rural and agricultural communities typically lags behind their more urban counterparts, in part due to their unique infrastructure, and this project will take an integrated research and education approach to enhance their resilience. Findings related to the performance of steel grain bins will be translated directly to manufacturers. An integrated infrastructure and rural community resilience model will enable individual communities to evaluate their resilience accounting for their unique built environment. The education plan will contribute to diversifying and enhancing the future STEM workforce by increasing the number of rural students pursuing and persisting in engineering at the university level, where currently there exists a substantial gap between urban and rural students. A citizen science reconnaissance platform will be developed to further engage a wide range of rural citizens in the study and practice of disaster resilience. This project will contribute to the National Science Foundation (NSF) role in the National Earthquake Hazards Reduction Program (NEHRP) and the National Windstorm Impact Reduction Program (NWIRP). This overarching goal of this project is to generate a fundamental understanding of the performance of steel grain bins and the resilience of agriculturally based rural communities when subjected to earthquakes and straight-line windstorms. To reach this goal, the research plan will be comprised of two major research thrusts: steel grain bin vulnerability and community resilience impact assessments. Major research tasks for the steel grain bin will include high-fidelity numerical modeling of steel grain bins, large-scale seismic and aeroelastic testing, and development of metamodels to facilitate fragility analyses relating the hazard intensity to damage probabilities for a range of grain bins. Major tasks associated with the community resilience thrust will include the development of an agricultural community resilience model, which will be validated with respect to longitudinal structural and community reconnaissance, and the evaluation of mitigative measures to enhance resilience. This research will use the NSF-supported Natural Hazards Engineering Research Infrastructure (NHERI) Wall of Wind facility at Florida International University for aeroelastic testing and will archive and make publicly available project data in the NHERI Data Depot (https://www.DesignSafe-ci.org).This project is jointly funded by the Engineering for Civil Infrastructure (ECI) program and the Established Program to Stimulate Competitive Research (EPSCoR).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.
