The objective of this CiviL Infrastructure research for climate change Mitigation and Adaptation (CLIMA) research project is to establish a comprehensive framework for system integration, structural mechanics, and financing for nimble, adaptive, and reusable structures (NARS). The overarching idea behind NARS is to harness emerging concepts in origami-inspired deployable and reconfigurable structures for strategic, widespread and commercially viable applications in building infrastructure. These systems have the capacity to become transformative solutions for post-disaster recovery from - and adaptation to - climate change. NARS systems can offer several benefits including adaptable building plans, reusability, rapid assembly, automation in construction, and fabrication at distributed locations. The research program will establish simulation tools, design methods, experimental mechanics principles, smart financing models, and pertinent knowledge whose intent are accelerating and scaling nimble assembly, geometric adaptability, and reuse for modern construction. Virtual reality will be used to demonstrate the capabilities and potential of NARS to industry, government, and community stakeholders. The work will also contribute to the development and improvement of educational materials including: modules for a course that engages first-year students to pursue civil engineering with climate adaptable structures; lecture content for a graduate course focused on theory, analysis, and design for NARS-like systems; and graduate course use cases on contractual and financial innovation for sustainable infrastructure projects.The specific goals of the project include exploring building system integration, structural mechanics, and infrastructure financing for NARS systems. The research will establish simulation tools that provide insights on the assembly process, load bearing capability, geometric adaptability, constructability, and the impact of performance indicators on financing of NARS. Inverse design and optimization of thick origami will discover modular and adaptable systems that integrate into modern building structures. The effort will establish new mechanics-based experimental methods to test: (a) adaptability, where a system is reshaped and/or repurposed for different loading scenarios, and (b) reusability, where a system is deconstructed and reassembled multiple times. An experimental program for the project will provide insight on the mechanics of thick origami consisting of panels and hinges. Finally, this project will establish models and methods to evaluate the lifecycle cost to construct modular and reusable structures. The work will uncover appropriate financing structures and public-private partnership contracting options for delivery, and generate insights on how broader environmental, social, and governance (ESG) implications of NARS systems can reduce the cost-of-capital.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.

该气候变化减缓和适应民用基础设施研究 (CLIMA) 研究项目的目标是为系统集成、结构力学和灵活、适应性和可重复使用结构 (NARS) 的融资建立一个全面的框架。 NARS 背后的总体思想是利用折纸启发的可部署和可重构结构中的新兴概念，在建筑基础设施中实现战略性、广泛性和商业上可行的应用。这些系统有能力成为灾后恢复和适应气候变化的变革性解决方案。 NARS 系统可以提供多种优势，包括适应性强的建筑规划、可重复使用性、快速组装、施工自动化以及分布式地点的制造。该研究计划将建立模拟工具、设计方法、实验力学原理、智能融资模型和相关知识，其目的是加速和扩展现代建筑的灵活装配、几何适应性和再利用。虚拟现实将用于向行业、政府和社区利益相关者展示 NARS 的能力和潜力。这项工作还将有助于教育材料的开发和改进，包括：让一年级学生学习气候适应结构土木工程的课程模块；研究生课程的讲座内容侧重于类似 NARS 系统的理论、分析和设计；该项目的具体目标包括探索 NARS 系统的建筑系统集成、结构力学和基础设施融资。该研究将建立模拟工具，为装配过程、承载能力、几何适应性、可施工性以及性能指标对 NARS 融资的影响提供见解。厚折纸的逆向设计和优化将发现可融入现代建筑结构的模块化和适应性系统。这项工作将建立新的基于力学的实验方法来测试：（a）适应性，即系统针对不同的负载场景进行重塑和/或重新调整用途，以及（b）可重用性，即系统被多次解构和重新组装。该项目的实验计划将深入了解由面板和铰链组成的厚折纸的力学。最后，该项目将建立模型和方法来评估构建模块化和可重复使用结构的生命周期成本。这项工作将揭示适当的融资结构和公私合作伙伴关系交付合同选项，并就 NARS 系统更广泛的环境、社会和治理 (ESG) 影响如何降低资本成本提供见解。该奖项反映了 NSF 的法定要求使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
