Spread the Load: A simple technique uses many smaller wood pieces as support members Developing countries around the globe are rapidly using up all of their indigenous hardwoods. Constructing reciprocal framework structures allows the use of smaller, younger pieces of wood from timber farms rather than felling old-growth trees for construction. The load is spread out across many smaller members, so none need the strength typical of support beams. While the technique requires some engineering skills, assembly on-site is simple and can often be done without complex machinery.
