报告人简介:

Sigrid Adriaenssens目前是美国普林斯顿大学土木与环境工程系的副教授,结构找型实验室负责人,主要从事固体力学和柔性结构非线性力学、结构设计以及工程艺术方面的科研和教学工作。她的主要研究方向是极端荷载作用下的大跨度空间结构力学和设计,近期研究方向转向了数字建造。她一直致力于建立一个服务于自动化结构设计优化的整体框架,其中包括解析公式、数字化找型和优化方法、流固耦合、机器学习模型和算法等。在应用方面,她使用这个框架成功地在建筑尺度创造了自适应遮阳装置和大型防浪结构。她与2018年获得了美国土木工程协会(ASCE)乔治·温特奖。2021年,她被任命为ASCE结构分会会士,国际壳层与空间结构协会(IASS)副主席,获得同济大学主办的数字未来Matthias Rippmann奖和以及英国萨里大学空间结构研究中心先锋奖。同时,她担任ASCE结构美学设计分委会主任和IASS混凝土壳分会的主任,同时也是International Journal of Space Structures的联合主编。

 

Sigrid Adriaenssens is currently an associate professor who directs the Form Finding Lab at Princeton University’s civil and environmental department, where she teaches courses on (non‐)linear mechanics of solids and slender structures, structural design, and the integration of engineering and the arts. Her research interests lie in the mechanics of large‐span structural surfaces under extreme loading and more recently under construction. She has been working on a comprehensive framework with advanced analytical formulations, numerical form finding and optimization approaches, fluid/structure interaction, and machine learning models and algorithms to open new avenues for accelerated discoveries and automated optimal designs. In terms of applications, she has used this framework to successfully innovate structural and architectural systems ranging from macroscale adaptive shading shell devices to large‐scale storm surge membrane barriers. In 2018 she received the ASCE George Winter Award. In 2021, she was named Fellow of the Structural Engineering Institute of the American Society of Civil Engineers (ASCE), elected vice‐president of the International Association of Shell and Spatial Structures (IASS), and received the DigitalFUTURES Matthias Rippmann Award (Tongji University, China) and the Pioneers’s Award (Spatial Structures Research Centre of the University of Surrey, UK). She chairs the ASCE Esthetics in Design Committee as well as the IASS Concrete Shell Roofs Working Group. She is the co‐editor of the International Journal of Space Structures.

 

报告摘要:

2050年,将有至少70%的世界人口居住在城市中。结构工程师肩负着在这些城市创想、设计和建造人类赖以生存结构物的重任。建筑业是资源最密集的行业之一,但我们的城市基础设施仍在大规模地以传统形式建设,通过堆积材料质量来获得强度。相反,普林斯顿大学的结构找型实验室(Form Finding Lab),一直专注于研究具有合理受力分布、轻薄、经济和低碳的曲面结构。结构找形实验室的核心研究问题是“建筑尺度下结构形式和工作性能的关系是什么?”正因为此,实验室探索了诸多依靠几何非线性、拥有奇妙力学性能、却使材料依然处于弹性阶段的壳结构、膜结构和杆系网结构。它们的几何形状和拓扑结构赋予了它们超越传统结构系统的特性。在这次演讲中,Adriaenssens教授将简述她课题组近期有关一些高性能和新功能大型结构从概念提出、到设计分析,再到建造结构的全过程。这些结构可以有效承受极端载荷、自我组装、调整刚度、切换不同的稳定状态,甚至获得变形增强等效应。

 

By 2050, 70% of the world’s population will live in cities. Structural engineers envision, design and construct structures that those city dwellers depend on daily. The construction industry is one of most resource-intensive sectors, and yet our urban infrastructure continues to be built in the massive tradition in which strength is pursued through material mass. In contrast, we, at the Form Finding Lab at Princeton University, have focused our research on structural systems that derive their performance from their curved shape, dictated by the flow of forces. As a result, these structures can be extremely thin, cost-effective, and have a smaller carbon footprint. Our core research question is ‘What is the relationship between form and efficiency in civil-scale structures?’. Shells, membranes, and rod networks exhibit fascinating mechanical behaviors because geometric nonlinearities arise even when their material properties are linear. Their shape and topology give them properties beyond what is possible with conventional structural systems. In this talk, we outline how we discovered, studied, designed and even built large-scale structural surfaces that can efficiently carry extreme loading, self-assemble, adjust their stiffnesses, elastically shift from one shape to another, or amplify motion.
