abstract

Disaster zones are often full of “found” material which are debris that can be recycled and used to build practical structures. In this paper, the question of how to build truss structures from these members of arbitrary geometry is introduced and a solution presented. Assuming a set of “found” truss members is provided and that each beam is made from a set of piecewise lines, they are approximated as straight. This is done to simplify the optimization process. A general linear search is then used to investigate possible structures until an optimal structure, with respect to weight and similarity to a desired construction, is found.
