CLIMA: Nimble, Adaptive, and Reusable Structures (NARS): Systems, Mechanics, and Financing

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、适应和可重复使用的结构(NARS)融资建立一个全面的框架。NARS背后的总体思想是利用以折纸为灵感的可部署和可重新配置的结构中的新兴概念，用于在基础设施建设中具有战略意义、广泛和商业可行性的应用。这些系统有能力成为灾后从气候变化恢复和适应气候变化的变革性解决方案。NARS系统可以提供几个好处，包括可适应的建筑计划、可重复使用、快速组装、施工中的自动化以及分散地点的制造。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，其意图是加速和缩放灵活组装、几何适应性和现代建筑的再利用。虚拟现实将被用来向行业、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材的开发和改进，包括：一年级学生学习具有气候适应性结构的土木工程的课程模块；研究生课程的授课内容，重点是类似NARS系统的理论、分析和设计；以及可持续基础设施项目的合同和金融创新的研究生课程使用案例。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。这项研究将建立模拟工具，为NARS的组装过程、承载能力、几何适应性、可施工性和绩效指标对融资的影响提供见解。厚折纸的反向设计和优化将发现模块化和适应性强的系统，这些系统整合到现代建筑结构中。这项工作将建立新的以力学为基础的实验方法，以测试：(A)适应性，即根据不同的加载情况重塑和/或改变系统的用途，以及(B)可重用性，即系统被多次解构和重组。该项目的一个实验计划将提供对由面板和铰链组成的厚折纸的机械原理的见解。最后，本项目将建立模型和方法来评估生命周期成本，以构建模块化和可重用的结构。这项工作将揭示适当的融资结构和交付的公私合作伙伴关系合同选项，并深入了解NARS系统的更广泛的环境、社会和治理(ESG)影响如何降低资本成本。该奖项反映了NSF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。

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.
