The computational challanges of a mega spaceframe
Paper i proceeding, 2017
The modeling of the envelope and space frame for the new Mexico City Airport was a massive computational task, demanding the development of numerous new methods, tools and processes to deal with its complexity and scale. The shape of the envelope was created through form finding, leading to an all-encompassing lightweight shell with internal spans reaching 130 m. This paper will
discuss the challenges faced and the methods used to develop a visually continuous and smooth space-frame model and envelope, while simultaneously complying with very strict spatial and
programmatic constraints and structural optimisation criteria. It will further explain how dynamic
relaxation was complemented with bespoke mechanisms for mesh manipulation, interfacing and
mesh smoothing to fine-tune the final form.
