Collaborative Research: Tessellated Structural-Architectural Systems for Rapid Construction, Repair, and Disassembly

最近发生的自然灾害提醒人们，下一代建筑应尽量减少极端荷载的经济和社会后果，同时尽量减少对环境的影响。本研究探讨了一种新的综合结构建筑墙系统，利用棋盘格图案，重复的元素的安排，以产生建筑物，可以有效地建造，维修，重新配置和解构。Tessellated Structural Architectural（TeSA）系统可以通过在极端事件发生后快速修复和重新占用来促进恢复力，以及通过材料、结构元件和建筑物的再利用和适应性来促进可持续性。TeSA系统的好处之一是促进建筑物的适应和解构，这是减少陈旧的策略，这是建筑物拆除的主要原因，并限制拆除碎片的环境足迹，同时增加建筑物的生命周期，因为它们可以灵活地适应未来的使用。随着城市化的继续发展，对这些福利的需求可能会增加。大学课程和从业者研讨会将用于传播研究成果，并鼓励其在建筑行业的应用。本研究项目将研究和了解多种TeSA系统的基本差异。不同类别的镶嵌墙系统，包括1D和2D拓扑联锁镶嵌的结构行为将通过验证模型进行研究。分析模型，物理实验和概率评估将被用来集中在镶嵌结构的损坏和修复/更换损坏的元素在建筑规模的影响本地化。研究还将建立一个决策框架，使建筑师和工程师的综合团队能够利用脆弱性曲线作为传达材料和建筑系统设计决策影响的视觉手段。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。

Recent natural disasters are reminders that the next generation of buildings should minimize economic and social consequences of extreme loading with minimal environmental impact. This research investigates a new integrated structural-architectural wall system which utilizes tessellated patterns, an arrangement of repetitive elements, to produce buildings that can be efficiently constructed, repaired, reconfigured, and deconstructed. Tessellated Structural Architectural (TeSA) systems can contribute to resilience through rapid repair and reoccupation after an extreme event, as well as to sustainability through reuse and adaptability of materials, structural elements, and buildings. Among the benefits of TeSA systems is to facilitate building adaptation and deconstruction, which are strategies for mitigating obsolescence, a primary cause of building demolition, and limiting the environmental footprint of demolition debris while increasing the lifecycle of buildings as they are flexible to adapt to future uses. The need for these benefits will likely increase as urbanization continues to increase. University coursework and practitioner workshops will be used to disseminate research results and encourage their application in the construction industry.This research project will study and understand fundamental differences of multiple classes of TeSA systems. The structural behavior of diverse classes of tessellated wall systems, including 1D and 2D topologically interlocking tessellations will be investigated through validated models. Analytical models, physical experiments, and probabilistic assessments will be used to focus on localization of damage in tessellated structures and the effects of repair/replacement of damaged elements at the building scale. Research will also create a decision framework whereby integrated teams of architects and engineers can utilize fragility curves as a visual means of communicating the effects of design decisions concerning materials and building systems. It will provide architects and engineers with validated methods and a demonstrated framework for designing TeSA systems of their own creation.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.
