壹：建竹工坊
1. Archi Bamboo Co-op

2016年10月12日——10月14日，第九届中国竹文化节将在竹编艺术之乡——四川省青神县举办。8月初某天，设计师们讨论为此次活动设计室外标识竹装置，其共识是：当代原竹设计对话传统原竹工艺。由建筑师、结构工程师和竹木工程师组成的联合体“建竹工坊”诞生，在成都和深圳2个城市通过互联网，开始为期2月的讨论、设计、研发和建造……设计师具有不同的专业背景，却对原竹传统工艺以及当代创新应用的共同兴趣。

The 9th Bamboo Cultural Festival of China would be held in Qingshen County,Sichuan Province, which is famous for vernacular bamboo waving art. The design team proposed to erect an iconic outdoor installation for the event. The vision was to create a dialogue between contemporary bamboo design vs. traditional bamboo waving. Archi Bamboo Co-op(ABC), a team of architect, structural engineer, and bamboo expert was established for the task. In the following two months, an online discussion group, kept the design moving, crossing the city of Chengdu and Shenzhen. The designers with diverse backgrounds shared the same interests in revitalizing traditional bamboo log techniques.

建筑师杨保新：“现代原竹建筑未能大量运用并推广，其瓶颈在于没有很好地解决材料处理和节点标准化的问题，应该建立这类非标材料的完整设计和建造体系。”
Baoxin Yang, architect: “the bottle neck to put bamboo log in modern mass production, lies in the standardization of material treatment and detail design. There should be a complete design and construction system for non-standard material like bamboo log.”

建筑师李甫：“原竹通常被认为是乡土材料，适用于传统语境。如何突破常规，在当代城乡语境中进行批判性表达？”
Fu Li, architect: “bamboo log was regarded as vernacular material suitable to traditional design language. How to break the stereotype, and set it in a contemporary context?”

结构工程师林超伟：“充分利用原竹材性，扬长避短，宜通过巧妙的轻型结构体系展示力学的视觉张力。”
Chaowei Lin，structural engineer: “To take advantage of the structural strength of bamboo, it is important to showcase the visual impact of a clever light weight structure.”

竹材专家黄坤：“尽管重组竹工艺进年发展迅猛，但环保无害是原竹建筑和产品的极大优势。”
Kun Huang, bamboo expert: “although laminated bamboo was rapidly developed recently, but bamboo log do have huge ecological advantages.”

 

贰：创意
2. Concept

设计师们讨论后决定建造一座张拉体竹塔作为竹文化节的标志展品。伟大的发明家富勒在六十年代提出了张拉结构体系，充分发挥杆件受压和索件受拉的特性，以极少材料实现高跨空间。这一突破性的结构形式嫁接到中国最接地气的建筑材料-原竹上，放置在四川本土的城乡环境中，会呈现怎样的状态？

After discussion，designers decided to build a tensil bamboo structure as the iconic installa-tion for the bamboo cultural festival. The great inventor and architect Buckminster Fuller invented tensil system in 1960’s. The compression on the frames and tension on the cables work to-gether to occupy maximum height and span with minimum material. How interesting it would be, if we apply this modern structural system to the traditional material-bamboo, in a very local Si-chuan urban-rural context?

这是一个多专业合作的设计过程。材料学提供文献研究和实验统计的基础数据，建筑学控制空间几何体的变量参数，结构工程学进行参数化计算和优化，在各项变量中分析出最合理的结构受力模型，最终生成出“材料-结构-建筑”一体化的空间几何形式。此后在成都现场，设计师进行1:1比例的部分建造实验，检验理论计算的结果。现场实验的重点是节点研究、单元研究和单元组合研究。

It is a co-operation among multi professions. The bamboo expert provide basic data and re-searches of the material, structural engineer optimize the structure with parametric tool, to find the best force flow, architect provide vision of the formal and spatial concept. Finally, a trinity of ‘material-structure-form’ geometry was produced. A 1:1 mock-up was built in Chengdu to verify the theoretical design, especially the prototypes of joint and unit, and combination of units.

叁：制作
3. Installation

立足于’工匠精神’和实验精神’基础上的实践是建竹工坊的核心观念，设计师们亲自动手并全过程制作。中国传统竹工艺博大精深，设计师走访竹编之乡，学习和研究传统技艺，最终选用原竹特有的几种无害着色工艺：蓝绿：慈竹本色；黄绿：麻竹本色；浅绿：刮青；浅黄：干燥本色；中褐：中度炭化。
在地建造要求就地取材，因材施用。最终在当地选用慈竹、楠竹和麻竹满足了不同部位的结构要求。

A core value of Archi Bamboo Co-op is experimental practices with handcrafts man spirits. The designers rolled up sleeves to take part in the process of installation. Based on the traditional skills used by local handcrafts men, they improved the properties and techniques through scientific researches. The results of the researches were echo harmless colors unique to bamboo log：natural green, dried light yellow, shaved white, carbonized brown. They also differentiated local bamboo species for different structural requirements.

肆：失重
4. Un-gravity

第九届中国竹文化节开幕现场， 10米高竹塔，15根彩色原竹，漂浮并消隐在城市背景和热闹的展会人群中。会后，竹塔由四位工人抬着经过县城街道，整体安置在乡村稻田中，成为稻田中的公共艺术。2017年，春暖花开，油菜花海，经过半年的耐力试验后，竹塔将被拆解，竹竿和钢索被分类回收等待新的利用。 再见漂浮的五彩原竹。

In the open ceremony of the bamboo cultural festival, the 10 meter high bamboo tower of 15 colorful logs, float in air, as if un-gravitized. it merged into the exhibition crowd and urban background. Four farmer workers carried it to re-install in the rice field. In 2017 spring, after a half-year durability test, the tower will be disassembled, and recycled on future project. See you again, bamboo tower.

这次快速而轻巧的实验，模糊了建筑、结构、材料、雕塑和装置的边界。 它游走在传统和现代，建筑和艺术，城市和乡村的边缘。 失重，既指向竹子本身的漂浮状态，也指向整个装置的机动状态。 它将激发出更多未知的尝试。

This fast and light weight experiment, blurs the boundaries of architecture, structure , mate-rial ,installation and sculpture. It is a blend between tradition and modernity, architecture and art, city and countryside. The concept of un-gravity, not only expresses the floating condition of the bamboo logs, but also points to the mobility of the installation. It will inspire more unknown experiment.
