The Natural Hazards Engineering Research Infrastructure (NHERI) will be supported by the National Science Foundation (NSF) as a distributed, multi-user national facility that will provide the natural hazards engineering community with access to research infrastructure. NHERI will be comprised of separate research infrastructure awards for a Network Coordination Office (NCO), Cyberinfrastructure (CI), Computational Modeling and Simulation Center (SimCenter)-this award, and Experimental Facilities for earthquake and wind hazards engineering research, including a post-disaster, rapid response research (RAPID) facility. NHERI awards will contribute to NSF's role in the National Earthquake Hazards Reduction Program (NEHRP) and the National Windstorm Impact Reduction Program. NHERI continues NSF's emphasis on earthquake engineering research infrastructure previously supported under the George E. Brown, Jr. Network for Earthquake Engineering Simulation as part of NEHRP, but now broadens that support to include wind and coastal hazards engineering research infrastructure. NHERI has the broad goal of supporting research that will improve the resilience and sustainability of civil infrastructure, such as buildings and other structures, underground structures, levees, and critical lifelines, against the natural hazards of earthquakes and windstorms, in order to minimize loss of life, damage, and economic loss. Information about NHERI resources is available on the NHERI CI web portal (http://www.DesignSafe-ci.org). This award will provide the SimCenter component for NHERI. The goal of the SimCenter is to provide the natural hazards engineering research and education community with access to next generation computational modeling and simulation software tools, user support, and educational materials needed to advance the nation's capability to simulate the impact of natural hazards on structures, lifelines, and communities, and to make informed decisions about the need for and effectiveness of potential mitigation strategies. These tools will be available on the NHERI CI's DesignSafe-ci.org Discovery Workspace. The SimCenter will provide computational modeling and simulation tools using a new open source simulation framework that: (1) addresses various natural hazards, such as windstorms, storm surge, tsunamis, and earthquakes; (2) tackles complex, scientific questions of concern to disciplines involved in natural hazards research, including earth sciences, geotechnical and structural engineering, architecture, urban planning, risk management, social sciences, public policy, and finance; (3) utilizes machine learning to facilitate and improve modeling and simulation using data obtained from experimental tests, field investigations, and previous simulations; (4) quantifies uncertainties associated with the simulation results obtained; (5) utilizes the high-performance parallel computing, data assimilation, and related capabilities provided by the DesignSafe-ci.org web portal to easily combine software applications into workflows of unprecedented sophistication and complexity; (6) extends and refines software tools for carrying out performance-based engineering evaluations and supporting decisions that enhance the resilience of communities susceptible to multiple natural hazards; and (7) utilizes existing applications that already provide many of the pieces of desired computational workflows. The resulting cloud-based ecosystem will allow multidisciplinary specialists and various stakeholders to collaborate on solutions to complex natural hazard engineering problems regardless of their local resources and geographic proximity. In tandem with the framework and applications being developed, in-person and online educational programs, including massive open online courses, will be implemented within a new Virtual Community of Practice that will provide an online meeting place to obtain and exchange community-generated ideas, feedback, best practices for modeling and simulation, insights, and innovations for natural hazards engineering research. The SimCenter will also provide user workshops and a graduate student research traineeship program and will host two students as part of the NCO's Research Experiences for Undergraduates program.

自然危害工程研究基础设施（NHERI）将由国家科学基金会（NSF）作为分布式的多用户国家设施的支持，该设施将为自然危害工程社区提供研究基础设施。 NHERI将由网络协调办公室（NCO），网络基础设施（CI），计算建模和仿真中心（Simcenter）（SIMCENTER）的单独研究基础设施奖项组成 - 这是该奖项以及地震和风危害工程研究的实验设施，包括一项后置换式研究，快速响应研究（快速响应研究（快速）的设施（快速）。 NHERI奖将有助于NSF在国家地震危害计划（NEHRP）和全国风暴影响减少计划中的作用。 NHERI继续NSF强调地震工程研究基础设施，以前在George E. Brown，Jr。地震工程模拟网络中作为NEHRP的一部分进行了支持，但现在扩大了支持，包括风风和沿海危害工程研究基础设施。 NHERI的广泛目标是支持研究，以改善民用基础设施的弹性和可持续性，例如建筑物和其他结构，地下结构，堤防和关键寿命，以应对地震和风风暴的自然危害，以最大程度地减少生命，损失以及经济损失。有关NHERI资源的信息可在NHERI CI Web门户网站（http://www.designsignsafe-ci.org）上获得。该奖项将为Nheri提供Simcenter组件。 Simcenter的目的是为自然危害工程研究和教育社区提供下一代计算建模和仿真软件工具，用户支持以及促进国家对模拟自然危害对结构，寿命和社区的影响的能力所需的教育材料，并为潜在的缓解策略的需求和有效性做出知情的决策。这些工具将在Nheri CI的DesignSafe-ci.org Discovery工作区中找到。 Simcenter将使用新的开源仿真框架提供计算建模和仿真工具，该框架：（1）解决各种自然危害，例如风暴，风暴潮，海啸和地震； （2）解决参与自然危害研究的学科的复杂，科学问题，包括地球科学，岩土技术和结构工程，建筑，城市规划，风险管理，社会科学，公共政策和金融； （3）利用机器学习来利用从实验测试，现场调查和以前的模拟获得的数据来促进和改善建模和模拟； （4）量化与获得的模拟结果相关的不确定性； （5）利用DesignSafe-ci.org Web门户提供的高性能并行计算，数据同化以及相关功能轻松将软件应用程序组合到前所未有的复杂性和复杂性的工作流中； （6）扩展并完善了用于进行基于绩效的工程评估和支持决策的软件工具，从而增强了易受多种自然危害的社区的韧性； （7）利用现有的应用程序已经提供了许多所需的计算工作流程。由此产生的基于云的生态系统将使多学科专家和各种利益相关者能够在复杂的自然危害工程问题的解决方案上合作，无论其本地资源和地理位置如何。与开发的框架和应用程序的同时，将在一个新的虚拟实践社区中实施，包括大规模开放的在线课程，包括大规模开放的在线课程，该课程将提供一个在线聚会场所，以获取和交换社区生成的想法，反馈，最佳实践，建模和模拟，仿真，洞察力，洞察力，以及自然危害工程研究的创新。 Simcenter还将提供用户研讨会和研究生研究培训计划，并将接待两名学生，作为NCO本科生研究经验的一部分。
