I am surprised that the Chinese haven't figured out a way to
make bamboo studs and beam from the fiber.

The Chinese are more interested in eating the shoots than playing with the
bamboo fiber.

Seriously, have you seen the use of bamboo as scaffolding in high-rise
buildings in places like China and Hong Kong? Its preferred over steel
scaffolding in that part of the woods. As for bamboo studs and beams I think
its stronger than wood per weight but how do you nail it together?
