Matts and all -
Bob Bolles did a pretty good test for out of plane load on a
bamboo-corsetted wall, and we test design folks have decided to omit all
forms of pinning from all tests. That way, we won't compel anyone
henceforth to having to pin, and are confident that we'll get good
structural values anyway.
We still won't know for sure how much interior or exterior pins contribute
to strength, be they rebar or bamboo, but hopefully will no longer care.
That's the theory, anyway.
