报告人简介：

Philippe Block是苏黎世ETH建筑技术研究所（ITA）的教授，与Tom Van Mele博士一起指导Block研究小组（BRG），并担任该研究所所长。他还是瑞士国家研究中心数字化建造的主任并且担任ODB工程咨询公司的联合创始人。Block教授从事了多学科交叉领域的工作，涉及图解静力学、计算结构找型、结构设计优化，数字建造和工艺等。他曾获得国际空间结构协会Hangai Prize和Tsuboi Award，以及Edoardo Benvenuto prize(2012), the Berlin Art Prize for Architecture (2018)等多项国际大奖。他曾在比利时布鲁塞尔Vrije大学（VUB）和美国麻省理工学院（MIT）学习建筑和结构工程，并于2009年在麻省理工获得博士学位，师从John Ochsendorf教授。

Prof. Dr. Philippe Block is a full professor at and head of the Institute of Technology in Architecture (ITA) at ETH Zurich, where he co-leads the Block Research Group (BRG) with Dr. Tom Van Mele. He is director of the Swiss National Centre of Competence in Research (NCCR) in Digital Fabrication, and founding partner of Ochsendorf DeJong & Block (ODB Engineering).Prof. Block’s multi-disciplinary research interests span graphical design and analysis techniques, computational form finding and optimisation, structural and architectural geometry, digital fabrication and appropriate construction. Prof. Block has received numerous awards and recognitions for his research, including the Hangai Prize (2007) and the Tsuboi Award (2010) from the International Association of Shell and Spatial Structures (IASS), the Edoardo Benvenuto prize (2012) for scientific research on the history of Structural Mechanics and Art of Building, the Berlin Art Prize for Architecture (2018), given by the Academy of Arts, and most recently the Rössler Prize (2018) for most promising young professor at ETH Zurich.He studied architecture and structural engineering at the Vrije Universiteit Brussel (VUB) in Belgium and at the Massachusetts Institute of Technology (MIT) in the US, where he earned his PhD in 2009.

报告摘要：

混凝土并不想以梁的构造呈现，它更适合于“拱”型。将混凝土建构在纯受压的空间结构中，可以显著减少材料用量。随着当今计算图形学、工程分析方法以及数字化建造等领域的发展，混凝土可以作为一种可持续的解决方案用于常见的各类结构构件中，比如楼板或拱桥。本讲座将介绍在苏黎世理工学院的数字建造实验室如何重塑混凝土建构，使这些结构能具备轻质、低碳、无筋、低能耗、可再生、耐火、保温、声学性能优良、可预制组装，以及作为结构部件轻松拆卸和重复使用，或者在使用寿命结束时实现便捷回收.......这些理念均有潜力在全球范围内大规模使用，并且成本效益显著。听起来是否好得令人难以置信呢？

Concrete does not want to be a beam, it wants to be an arch. Reintroducing funicular geometry for spanning space in concrete makes it possible to significantly reduce the amount of material needed, but also, because of the very low stresses, build with lesser emitting materials. Recent developments in computational design and engineering methods and construction-scale digital fabrication now allow us to introduce concrete as an extremely sustainable solution for common structural elements like a floor “slabs” or a arched bridges. This lecture will introduce how we can disrupt concrete construction: lightweight, extremely low embodied emissions, no embedded reinforcement steel, using very little resources and made largely out of construction demolition waste, fire resistant, providing thermal mass, acoustically performant, dry-assembled prefab, so easily demountable and reusable as structural components or entirely and easily recyclable at the end of its life, available at scale and globally, and economic. Sounds too good to be true?
