史无前例的结构
IBUKU开创了一个新的设计词汇，沿途制定了我们自己的规则，并通过我们的旅程向世界提供新的解决方案。今天，我们提供了另一个设计方案，一个前所未有的结构，它不仅是一个令人难以置信的竹建筑作品，而且将成为轻质结构的一个参考。

An Unprecedented Structure
IBUKU has pioneered a new design vocabulary, making our own rules along the way, and offering new solutions to the world through our journey. Today, we offer yet another design solution, an unprecedented structure which is not only an incredible piece of bamboo architecture, but will serve as a reference in lightweight structures altogether.

弧形建筑是位于印度尼西亚巴厘岛的世界知名的绿色学校校园内的最新建筑。这所学校有12年的历史，打破了界限，扩大了视野，而Arc是这一历史中最新的基准，提高了全世界可持续教育的标准。绿色学校的弧形建筑是有史以来第一座此类建筑，由一系列相交的14米高的竹拱门建成，跨度为19米，由反弹性网格壳相互连接，其强度来自于两个相反方向的弯曲。

The Arc is the newest building on campus at the world-renowned Green School in Bali, Indonesia. The school has a 12 year history of breaking boundaries and expanding horizons and the Arc is the newest benchmark in that history, raising the bar for sustainable education around the world. The first building of its kind ever made, The Arc at Green School is built from a series of intersecting 14 meter tall bamboo arches spanning 19 meters, interconnected by anticlastic gridshells which derive their strength from curving in two opposite directions.

拱门是一个工程的壮举；它需要数月的研究和开发，并对量身定做的细节进行微调。其结果是一个精致的设计，具有无与伦比的美感，证明了IBUKU致力于扩大建筑和设计的视野。

The Arc is a feat of engineering; it required months of research and development and fine tuning of tailor-made details. The result is a refined design with unparalleled beauty, which stands as a testament to IBUKU’s commitment to expanding horizons in architecture and design

The Arc的概念结构是完全前所未有的。开始一个从未执行过的设计需要一些勇敢和乐观的态度。我们有足够的创造力和毅力去研究和开发该项目成功所需的答案。

The concepted structure for The Arc is totally unprecedented. Embarking on a design never before executed required some bravery and optimism. We were creative and stubborn enough to research and develop the answers needed for the success of the project

巴厘岛绿色学校的拱门进入了有机建筑的新时代，其19米跨度的拱门，由反弹性网格壳相互连接。它是与Jorg Stamm和Atelier One合作，为这个非同寻常的校园提供的一个新的社区健康空间和体育场馆。

The Arc at Green School Bali enters a new era for organic architecture, with its 19 meter span arches, interconnected by anticlastic gridshells. It is a new community wellness space and gymnasium for the extraordinary campus, in collaboration with Jorg Stamm and Atelier One.

灵感来自于大自然
弧线采用了自然界最伟大的策略之一，以最小的结构创造大空间。在人类的肋骨中，一系列的肋骨以压缩的方式工作，由肌肉和皮肤组成的紧张的弹性层固定。这为肺部创造了一个薄而坚固的保护层。在 “弧 “的例子中，在压缩中工作的拱门被紧张的反弹性网格壳所固定。这些格子壳的领域似乎在不可能的薄拱门之间的空间中垂下，给空间带来一种奇异、亲密和美丽。虽然，这些网格壳看起来是挂在拱门上的，但它们实际上是把拱门撑起来的。

Inspired by Nature
The Arc employs one of nature’s greatest strategies for creating large spaces with minimal structure. Within a human ribcage, a series of ribs working in compression are held in place by a tensioned flexible layer of muscle and skin. This creates a thin but strong encasement for the lungs. In the case of The Arc, arches working in compression are held in place by tensioned anticlastic gridshells. These fields of gridshells appear to drape across the spaces between impossibly thin arches soaring overhead, giving a whimsy, intimacy and beauty to the space. Although, the gridshells appear to hang from the arches, they actually hold them up.

网壳利用形状的硬度来形成屋顶围护，并为抛物线拱门提供抗压性。这两个系统共同创造了一个独特而高效的结构，能够在负载下弯曲，使结构重新分配重量，缓解拱门上的局部力量。
尼尔-托马斯，Atelier One的总监

The gridshells use shape stiffness to form the roof enclosure and provide buckling resistance to the parabolic arches. The two systems together create an unique and highly efficient structure, able to flex under load allowing the structure to redistribute weight, easing localised forces on the arches.
-Neil Thomas, Director of Atelier One

弧形的几何形状的反直觉协调使结构进入平衡状态，这意味着对结构材料的需求大大减少。这也意味着一个史无前例的内部容积，其结构薄得不可思议，而且没有任何分散注意力的桁架。

The Arc’s counterintuitive orchestration of geometry brings the structure into a state of equilibrium, which means a dramatically decreased necessity for structural material. This also means an unprecedented inner volume with an impossibly thin structure and without any distracting trusses.
