Algoritmi di forma delle strutture reciproche

This work aims to develop a method for the design of a structural system to be used in variable span roofs. This algorithm allows to optimize geometry and material sections and, starting from roof shape and span, it can be used to highlight a good combination of beam size depending on the chosen topology. This proposal derives from a series of encounters with a group of small enterprises, based in Baselga di Piné (TN), and with Trentino Sviluppo agency. These small enterprises asked to use their short timber beams for long span roofs, as it happens with glued laminated timber (which requires a more advanced technology). A way to take advantage of the available technology, capable of producing only 5 metres long timbers, is to develop a system based on a limited number of elements, which can connect to each other in order to achieve a wide range of forms and dimensions. The use of reciprocal frame structures allows to span distances longer than the available beams. Being composed by a high number of elements, we have chosen to take advantage of symmetry and modularity to achieve a faster computation for this kind of structures. This work shows the potential of an ancient building system which can now become useful to open new markets for small enterprises based in Trentino.
