“…A reciprocal frame (RF) is a three-dimensional grillage structure based on elements (beams, elongated elements or laminae) that mutually support each other. The origins and general characteristics of RFs have been examined in depth previously in this journal (Di Carlo 2008;Duvernoy 2008; Baverel and Pugnale 2014; Pugnale and Sassone 2014; Thönnissen 2014) and will not be gone into here.…”

This paper deals with the use of reciprocal frames in temporary gridshell structures, such as architectural pavilions in expositions and installations. These architectural examples can benefit from the use of short, easy to handle, generally joint-free, and repeatable â\u80\u9cmodulesâ\u80\u9d in order to create particular self-supporting structures. The lightweight and interwoven grid obtained by connecting short elements according to the reciprocity principle is structurally efficient and, at the same time, aesthetically pleasing, mainly due to the resulting tessellation. The paper firstly investigates the connection between efficiency and aesthetics. The last part of the paper investigates some temporary architectural pavilions from both an aesthetical and parametric point of view. In order to deepen our understanding of these structures, they are re-modelled according to a bottom-up approach by means of a constraint-based parametric CAD modeller. In this way, a reciprocal frame can be explored and modified by the parametric arrangement of its generative elements, which, like a natural organism, grows in self-generating forms

Laminar Constructions and Reciprocal Structures

2017

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
