After one year development, we present a bamboo space frame with a new bamboo connection developed by us. The construction is a tetrahedron and with it the minute-possible demonstration of a 3-dimensional structure.

Linear grown bamboo is suitable for the reception of pressure and tensile forces ideally. Up to now, it neither was possible to realize complicated geometries, still it wasn't possible to take advantage of the high tensile strength of bamboo.

Now we solved these problems. The bamboo rods prefabricated by us with their connections meet in a knot, at which they are simply screwed on. At laboratory examinations about the tensile strength, we could prove, that our connection can use the full tensile strength of bamboo tubes.



Our students of architecture have designed bamboo space frame structures. Please have a look at the designs!

The simplicity of the assembly and the capability of our connection technology offers completely new perspectives and up to now undreamt-of possibilities for building with bamboo.

Comparative to construction metals (ie steels), how great is the tensile strength of bamboo?

And reading about bamboo makes me think of the frustration of archaeologists worldwide - bamboo is so useful and ergonomic for many cultures of Asia (and has been since H. erectus), but never lasts as long as flint or other lithic tools, so no ancient bamboo artifacts are ever found.

What a bright-looking group of students. Which is you? :)

According to this article, it depends. The range given (in ksi) is as follows:

steel 50-250
bamboo 50-75

Yes, they are aren't they? Sadly, I'm not among them.

like hemp, can be grown localy by future survivors to provide a base of materials to build new structures. that floating soda bottle island used a framewoek of bamboo to hold bags of bottles in place. however, like alternative energy and fuels, any future development in bamboo use be strickly by those whom want it as part of their self reliant needs. am I making any sense here?

Wow that's really awesome! So is this a research project for a graduate program?

Do you mind if I add you as a friend?
