Il legno lamellare tra limiti produttivi e potenzialità tecnologiche

The static conception of a warp of "curved beams" according to a horizontal position plane, hypothesized in glulam, it has had to confront with the impossibility of achieving structural elements with the desired geometry; the productive scenery, at present, solves only solutions arc mixtilinear, the only type derivable from the glulam with horizontal arrangement of the slats. This study, including the reasons for the detected limit, has investigated the technological feasibility of the glulam with a vertical arrangement of the slats, the only one that would allow a curvature in the horizontal position plane. To proceed in this direction, it was considered essential, advance, characterize the new material under the theoretical-experimental profile, analyzing the technical problems, to be addressed through a review of the production cycle, and researching the failure mechanisms, through a program of experimental tests. Validated the consistency of the hypothesis advanced, of which we report very encouraging results, you will have to face a technological reflection in the productive sector, to ensure the concrete possibility to start a dedicated production line to the beams in vertical glulam, linear or curved; then proceed to define a model of computation consistent with the structural efficiency found experimentally, such as to make possible their structural design.
