Frames Designed by Leonardo with Short Pieces. An Analytical Approach

Abstract

This paper deals with the analysis with actual mathematical tools of some structural proposals done by Leonardo in his notebooks. At difference of other subjects such as the Fly of Birds or Treatise of Painting, he never made his sketches to establish a coherent treatise on structures although he consumed a lot of pages analyzing constructional patterns to build bridges, roofs and floors a well vas beams, strings and mechanisms. May be he never constructed his proposals, but them are designed as if it would necessary to define minimal details. A particular subject contained in his notebooks are concerning to great span structures built with short elements. We try to proof the validity of these proposals.
