Bamboo is organic material that shape, caliber and bamboo joints are different, so it’s a restrict and hard to control material. The purpose of this project want to weave bamboo by algorithm computing and found the construction of double curve surface.

Bamboo Construction 34
The project aimed at minimal surface, expecting to create two force system of continuous surface. However, bamboo is straight originally, how to form double curve surface with itself and produce structural resistance at the same time without any force assistance is difficult problem. In the process, using the behavior of bamboo can weave itself to arrange them to three direction on the segmentation of surface. And then, it become weave consisted of the pattern of hexagon and triangle. Because this is double layer structural system, the first weaved layer should offset and segment again.

In the algorithm process, the surface will form seriously distort in the condition of high curvature. If compulsively segment the surface, it will cause serious twist of bamboo and the joint of triangular shear plate also have severely effect of distortion. Therefore, I try to segment surface to small unit, and the unit computing to weave by itself. However, the unit connect with other unit that cause the pattern of bamboo can’t be align and splice each other even have some unit connect with above five unit in the condition of complicated surface. In order to avoid the complicated algorithm of computing, the construction finally use the way of projection. Thus, the surface pattern can’t distort in the top view, but the diversity triangular shear plate turn to simplify. When in the high curvature surface, the triangular shear plate will elongate. However, those different length of triangular shear plate lead sunlight into interior in new way that form special atmosphere unexpectedly.

To put it simple, this structural system is similar to truss, there have shear plate structure to connect two weave layer in the triangle segmentation. Therefore, using algorithm computing to change the pattern of weaved to form different scale of hexagon and triangle can shape more complicated surface.
