Technique and countermeasures were proposed for transformation of low yieldtimber forest after analysis on its causes through investigation on current resources of low yield and scattered forest.
The deformation of the structure will mainly concentrates at the joints when structural damage occurs. The timber members remain elastic while the joint steel plates yield.
