Abstract
The empirical method in structural form finding has achieved world-wide efficiency and recognition as massive building tradition has continued to expand in history. Through direct involvement of lithoid materials, working under unilateral state of stress, designers driven by “static intuitions” have largely succeeded in giving shape to complex constructions, stabilized by gravity acting on the structural dead load mass (Fig. 1a).Ever since the second industrial revolution, with the help of materials able to carry tensile stresses, still the form of the structures have nevertheless been conceived and found observing the laws of statics, as a guarantee of an aesthetic result achieved. For membrane and cable structures, where the morphology must satisfy equilibrium conditions under an initial state of stress, finding the form of the structure is a “must” and, hence, a form finding procedure is required to identify the initial geometry. Nowadays, architects and engineers alike are immerged in a new challenge: the Free Form Design (FFD); a new fashion with the prevalence of aesthetics over static rationality where the role played by the structures is merely to support the architectural design Fig.1-b). Many novel projects attempt to extend the “state of the art” but, according to personal experiences, new structural morphologies adopted in actual conceptual design methodology generate uncertainties in reliability assessment [1][2].
