Laminar Constructions and Reciprocal Structures

Abstract

Reciprocal structures are constructed by using a wide variety of patterns. These designs are a good source of inspiration when working with laminar constructions (sheets). Using the same formal schemes, laminar constructions feature better bending of their elements along the shape of the model and the application of extra pressure on the connection joints. Many of the geometric constructions made at the University of the Basque Country and presented in this paper show structural, constructive and formal improvements in many reciprocal structures assembled using sheets instead of linear elements. Keywords Reciprocal frame structures Á Leonardo grids Á Laminar constructions Á Complex shapes Á Developable surfaces Reciprocal Structures Although reciprocal structures have probably been known since antiquity, the first detailed sketches are found in the folio 899v of Leonardo da Vinci's Codex Atlanticus (Williams 2008). In recent years the scientific community has begun to consider these structures as something more than a historical curiosity. Some scholars attribute to Villard de Honnecourt the first drawing of a reciprocal

Developable Wooden Surfaces for Lightweight Architecture: Bio-Dune Pavilion

“…The morphological approach has been carried out from graphic thinking, following the conceptual premises of Descriptive Geometry, the potential of digital tools, and parametric design. These surfaces can be studied from two different directions: on the one hand, the approximate processes can be studied in order to convert any type of surface into a discrete series of developable surfaces (González-Quintial et al 2013), (Barrallo et al 2017), or, on the other hand, they can be studied in order to morphologically enter into greater depth into the different ways of generating surfaces that are strictly developable in a continuous way.…”
