KnitCandela是一个薄薄的曲面混凝土壳体，框架由超轻的针织物构成。针织物部分在瑞士制作，用行李箱带到墨西哥。

KnitCandela is a thin, sinuous concrete shell built on ultra-lightweight knitted formwork that was carried to Mexico from Switzerland in a suitcase.

▼概览，overview

整个结构在墨西哥国立自治大学当代艺术博物馆进行组装，作为Zaha Hadid工作室在拉丁美洲的第一个展览。该项目是一个实验性结构，致敬了西班牙墨西哥建筑师兼工程师Félix Candela。设计师通过采用新的计算机设计技术和创造性的KnitCrete编织技术来重新构想Félix Candela别出心裁的混凝土壳结构。该项目动感的壳状结构是受到哈利斯科（墨西哥太平洋岸的州）传统服饰的流线造型启发。建造工人们亲切地称它为“sarape”（一种起源于墨西哥的条纹围巾），但事实上它的灵感来源于Félix Candela备受称赞的餐厅项目，在其后来的作品中也延续了同样的设计语言。

▼概念设计研究，conceptual design study

Constructed at the Museo Universitario Arte Contemporáneo (MUAC) in Mexico City as part of Zaha Hadid Architects’ first exhibition in Latin America, KnitCandela is an experimental structure that pays homage to the Spanish-Mexican architect and engineer Félix Candela. KnitCandela reimagines his inventive concrete shell structures through the introduction of new computational design methods and innovative KnitCrete formwork technology. The dynamic geometry of KnitCandela’s shell is inspired by the fluid forms of the colourful traditional dress of Jalisco, Mexico. While the structure’s local builders nicknamed the project ‘sarape’ (a striped scarf that originated in Mexico), KnitCandela’s form references his acclaimed restaurant at Xochimilco; a concept he further developed in several of his subsequent projects.

Candela建筑师结合夸张的曲面造型（“hypars”），创造可以再利用的结构，来减少建造过程中的浪费。现在设计师可以通过KnitCrete技术考虑更加自由的造型设计，这个制作索网和纤维框架的系统可以高效地制作出更具有表现力的混凝土结构，不再需要复杂的建模。薄薄的双曲面混凝土结构表面积约为50平方米，重量超过5吨，但为其提供支撑的KnitCrete纤维框架仅重55千克，仅靠行李箱就能从瑞士运到墨西哥。

While Candela relied on combining hyperbolic paraboloid surfaces (“hypars”) to produce reusable formworks leading to a reduction of  construction waste, KnitCrete allows for the realisation of a much wider range of anticlastic geometries. With this cable-net and fabric formwork system, expressive, freeform concrete surfaces can now be constructed efficiently, without the need for complex moulds. KnitCandela’s thin, double-curved concrete shell with a surface area of almost 50 sq.m. and weighing more than 5 tonnes, was applied on a KnitCrete formwork of only 55 kg. The knitted fabric of the formwork system was carried to Mexico from Switzerland in a suitcase.
