Descripción
Galileo postulated the existence of an insurmountable size for stone columns bearing a useful load as the size for which the structure is only able to resist its self-weight. Herein a method for the determination of the unsurmountable size for truss-like structures is shown, given the form of these structures and the ratio between the allowable stress and the specific weight of the material (the material structural scope). Three types of bars are considered: straight bars, with solid and hollow rectangular cross-section, and catenary bars with circular cross-section ?a limit and theoretical case for estimating a meaningful upper bound of the structural scope?. An approximate rule to estimate the structural efficiency ?here named GA rule? is shown, and is compared with numerical solutions using the proposed method.
