机器人切石法 麻省理工学院肖恩·科利尔纪念碑的建造

Robotic Stereotomy The MIT Sean Collier Memorial

麻省理工学院肖恩·科利尔纪念碑是为了纪念2013年在波士顿马拉松爆炸案中中枪身亡的肖恩·科利尔军官而建造的。文章介绍了这一永久性建筑物的设计与建造过程。设计将当代的数字建造技术、结构分析软件和计算技术与古老的纯受压穹顶技术相结合,创造出由硬石构成的五向穹顶和内部反射的中空拱形结构。这一建造包含由计算机控制的锯石和机械臂切石过程,以创造出多样的曲面石块。巨大的石块被运至现场由泥瓦匠依照复杂的搭建顺序装配完成。从方法论而言,麻省理工学院肖恩·科利尔纪念碑的设计流程是一个来回推敲的过程,即不断地进行数字模拟,在构建物理模型、模拟模型和数字模型的过程中进行优化设计。这一设计同时展现了以新兴数字建造方法为代表的当代技术和以传统石块砌筑技术为代表的永恒手工艺。

The Sean Collier Memorial was built in honor of Officer Sean Collier, who was shot and killed in the Boston Marathon bombings. This paper explores the design and fabrication process of the timeless structure. Combines age-old techniques for spanning vaults in pure compression with cutting-edge digital fabrication technologies, structural analysis software and computation, the memorial creates a shallow vaulted structure made of solid stone with a five-point figure and an inner space of reflection. The fabrication involves sophisticated stone carving by computer- controlled saws and a robotic arm to create the curved geometry of the blocks. The massive stone blocksare then set on-site by masons through an intricate scaffolding sequence. Methodologically, the design process for the Sean Collier Memorial involved a back and forth process between the construction of physical, analog, and digital models and simulations with digital tools. The design showcases both new digital fabrication methods as well as traditional stone setting masonry techniques, celebrating both contemporary technology and timeless craft.
