Stress of materials is useful to understand in order to fully utilize the basic properties of the material to the designer's advantage.
Bamboo is a very interesting material.http://en.wikipedia.org/wiki/Bamboo
High-quality bamboo is stronger than steel, a property that has made it a choice in building materials and weaponry.
Properly cured and dried, combine with epoxy or fibreglass, bamboo can be very srong.

Different methods exist to treat the bamboo poles and make them durable. All methods aim to cure the material in order to improve durability. One company smokes and heat-treats the bamboo. Others use a torch to achieve the same effect. Ovens can also be used. To prevent water-damage the bamboo can be coated with a sealant such as polyurethane.
The bamboo poles can be joined in different ways. The earliest models used metal joints which were then tightened around the bamboo. Another approach is to wrap the joints with resin saturated fibers to make composite lugs around the bamboo frame members.
