建筑设计构造装置木结构预应力科技普适性CODA

曾经杰出

CODA是一个专门研究通过计算机设计并优化轻量结构的小组，最终的目标是通过技

术和效率减少建筑行业的生态耗费。同时他们也坚信，科技发展会带来普世性的解决

方案。最近他们的研究主要集中在木结构的弹性与变形。2013年某个星期，8名成员

在匈牙利木建筑结构节上安装了这个名叫BigO的环形木壳。这个坚固的结构由十分简

单的元素---一系列笔直平滑的木板组成。这些4米长的木板被成员手工切割组合成100

条9.5长的单元条，然后进行现场组装。木板的弯曲产生了很好的预应力，在这个设计

中，修长而相互交叉的木板，因各自的力叠加而变得牢固。设计使得低技实现了高效

的结果。整个现场在与其它项目组研究学习交流的良好氛围下实现了建造。

CODA (Computational Design Affairs ) is a research group at BarcelonaTech
(Universitat Politècnica de Catalunya ). Their research is focused on the creation and
optimization of lightweight structures by means of computational design . Its ultimate
goal is to reduce the ecological footprint of the building industry through technological
efficiency. On the other hand, the group believe that technological development must be
democratic, and solutions universally accessible. Their recent research focuses on the
instrumentalization of the elastic deformation of timber structures.



CODA members Enrique Soriano and Pep Tornabell, were invited to participate in
HelloWood festival held each year in Hungary and bringing together young designers
and architects around wood construction. For a week and with the help of 8 students,
the group stepped forward in their research by conducting the project BigO, a toroidal
wooden shell. The aim was to build a very rigid structure but keeping affordability by
assembling simple elements. The strategy  was making a simple thin double curved
shell from slender straight  flat planks of massive timber.



Being a summer workshop, simple constructive solutions were welcome. This context
forced pragmatic solutions: the structure was assembled with 100 identical pieces of  
9.5 meters that were manufactured on a specifically built table. Original raw planks were
approximately 4 meters, with a section of 1 x 10 cm, so they had to be joint, cut, marked
and bored. Genuine digital manufacturing, not done by robots, but by enthusiastic
students with much precision. Both the detailing and the the setting-out on site were
solved with students experiencing specific material in- situ.
The experience produced two conclusions. The first is that the combination of anticlastic
curvature and surface synclastic produced a highly torsioned geodesic curve, that
induced high prestresses  in the planks, not only from the bending from the torsion. The
grid of coupled slender flexible planks, was then self-stiffened by the counteraction of
the prestresses. The structure  was achieved maintaining a low profile technology for a
highly efficient result.The second conclusion is that the group would definitely not have
been able to reach a similar result without the extraordinary good atmosphere in the
festival. The experience of researching, exchanging, and learning to implement
constructive solutions with the other groups was highly rewarding.

这是木得还是竹的？   我想起了王澍老师的那个千年穹啦，  是叫这个名字吗？！建构是俺们其中一个课程设计，当时选的砖，膜拜了一把刘克成的陕西国际陶艺博物馆...
