I would like to begin a case study in structural design using bamboo, which has currently become available to me. The design instance I would like to structurally copy is the Rogue RM-6 "Monster Rack" and a simple bench. Knowing that bamboo is used in scaffolding there must be details on structural reinforcement when binding stems together to make a structure. I would like to apply these kinds of principles to this rack design making necessary modifications where compromise is necessary. I do not know a good source to learn how make such structural binding techniques, so I thought to ask here if anyone here knows of one.

$\begingroup$ Assuming you will be using the bamboo in its natural form, (long tubes), why dont you just use standard joining techniques that you would use for any wooden structure, bamboo is really just a hard wood with a high silica content. $\endgroup$– William HirdNov 28, 2017 at 23:18

$\begingroup$ Yes, long, unseasoned tubes. 20' tall 3"/4" diameter base tapering to about a quarter inch. What is "standard joining," in your opinion, @WilliamHird? $\endgroup$– user13851Nov 28, 2017 at 23:25

$\begingroup$ Do some research in the coutries that use bamboo for scaffolding and many other things. $\endgroup$– Solar MikeNov 29, 2017 at 7:56

1$\begingroup$ @WilliamHird: Bamboo being mostly hollow tubes doesn't really work well for standard wood joining techniques like dovetail cuts. $\endgroup$– SF.Nov 29, 2017 at 15:11

Bamboo in its natural shape is very prone to splitting. Having any kind of hole will reduce its high bending strength resistance significantly.
In addition, bamboo culm does not have a constant cross-section in the longitudinal direction, makes it harder to create a reliable bond. J.F. Correal "Bamboo design and construction" has few suggestions for bamboo connections. the following are few of the typically used and suggested connections.
