This Faculty Early Career Development (CAREER) grant will bridge the gap between design and engineering by developing a robust computational framework for the use, development, and integration of geometry-based structural design methods in three dimensions. These methods, known as 2-D graphic statics (GS), are powerful geometric techniques that have been used to find efficient structural forms of many iconic bridges and long-span structures over the past 150 years. This program will establish the mathematical foundations of 3-D graphic statics, which has been very recently developed for finding architectural forms for high-performance structures. This research will devise computational tools to effectively build, control, and optimize structural forms in three dimensions. An open-source software, an interactive educational platform together with outreach activities will extend the accessibility and use of 3-D graphic statics by students, designers, and practitioners to learn, share, explore, and design innovative, high-performance, lightweight spatial structural solutions. The result of this project will open a new horizon for an unexplored realm of efficient spatial structural designs.The primary objective of this CAREER project is to develop mathematical methods and computational algorithms that (1) effectively construct convex and non-convex (self-intersecting) reciprocal polyhedral diagrams with certain user-input geometric constraints; (2) optimize the magnitude of external loads and the internal forces geometrically; (3) manipulate reciprocal polyhedral diagrams without breaking the topological and geometric dependencies of these diagrams; (4) allow for instant topological editing of both structural form and its force distribution; and (5) enhance the visualization of the reciprocal diagrams to increase design efficiency. This program will also provide a robust software platform and its related application programming interface for design, control and optimization of structures using 3D graphic statics. The software platform will be used in the education of a wide range of students, researchers, and practitioners and broaden the use of 3-d graphic statics in the design and fabrication of highly efficient, innovative, high-performance structural systems.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.

这项教师的早期职业发展（职业）赠款将通过为在三个维度的使用，开发和集成的使用，开发和集成的强大计算框架来弥合设计和工程之间的差距。这些方法被称为2-D图形静态（GS），是强大的几何技术，用于在过去150年中找到许多标志性桥梁和长跨度结构的有效结构形式。该程序将建立3-D图形静态的数学基础，该基础是最近开发的，用于寻找高性能结构的建筑形式。这项研究将设计计算工具，以有效地建立，控制和优化三个维度的结构形式。开源软件，一个交互式教育平台以及外展活动将扩展学生，设计师和从业人员对3D图形静态的可访问性和使用，以学习，分享，探索和设计创新，高性能，轻巧的空间结构解决方案。该项目的结果将为一个未开发的有效空间结构设计的领域打开新的地平线。该职业项目的主要目标是开发数学方法和计算算法，这些方法和计算算法（1）（1）有效地构建了具有某些具有某些用户用户输入的多面体图； （2）从几何上优化外部载荷的大小和内力； （3）操纵相互的多面图，而不会破坏这些图的拓扑和几何依赖性； （4）允许对结构形式及其力分布的即时拓扑编辑； （5）增强相互图表的可视化以提高设计效率。该程序还将提供一个强大的软件平台及其相关的应用程序编程接口，用于使用3D图形静态对结构进行设计，控制和优化。该软件平台将用于对广泛的学生，研究人员和实践者的教育，并扩大了3D图形静态的使用，以设计和制造高效，创新性，高性能的结构系统。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识优点和广泛的crietia的评估来通过评估来进行评估的，并值得通过评估。
