Reciprocal systems based on planar elements: Morphology, classification and design issues

Baverel, Olivier & Pugnale, Alberto

November 2012 | Conference Paper

This paper deals with the design of reciprocal spatial configurations based on the use of planar elements, which are investigated and classified according to their morphological characteristics and potential. Reciprocal structures are generally designed with the use of linear elements. Since their historical conception, at least in Western culture, they...


Engineering Architecture: Come il virtuale si fa reale (How Virtual Becomes Real)

Pugnale, Alberto

September 2012 | Article

In: "Bloom", vol. 14, pp. 17–24. Original Italian abstract (English text below): Negli ultimi vent’anni l’impatto del digitale in architettura è cresciuto esponenzialmente, manifestandosi nei ‘BLOB’ informi di Greg Lynn1, come anche nelle cosiddette ‘free-form’ dei NOX2. L’aggettivo ‘free’ identifica la libertà di generare forme architettoniche a prescindere da ogni...


Three-dimensional reciprocal structures: morphology, concepts, generative rules

Parigi, Dario & Pugnale, Alberto

May 2012 | Conference Paper

This paper presents seven different three-dimensional structures based on the principle of structural reciprocity with superimposition joint and standardized un-notched elements. Such typology could be regarded as being intrinsically three-dimensional because elements sit one on top of the other, causing every configuration to develop naturally out-of the plane. The structures...


Approaching technical issues in architectural education

Pugnale, Alberto & Parigi, Dario

May 2012 | Conference Paper

This paper discusses the teaching of technical subjects in architecture, presenting two experimental activities, recently organized at Aalborg University - a two-week-long workshop and a one-day long lecture. The activities are strategically placed between seminar-based subjects and architectural design studios, from the pedagogical point of view. On the one hand,...


Parametric Design and Construction Optimization of a Freeform Roof Structure

Kure, Johan, Manickam, Thiru, Usto, Kemo, Clausen, Kenn, Chen, Duoli & Pugnale Alberto

October 2011 | Conference Paper

In this paper, the design of a free-form roof structure is presented, approaching the problem in order to reduce construction costs and to define an efficient structural behaviour. The design process is supported by the use of a parametric tool, Grasshopper, for the definition of an optimization problem related to...


The principle of structural reciprocity: history, properties and design issues

Pugnale, Alberto, Parigi, Dario, Sassone, Mario & Kirkegaard, Poul Henning

September 2011 | Conference Paper

This paper deals with the principle of structural reciprocity, considering its origins in both Occidental and Orient culture and aiming to highlight the definition, main characteristics and interesting aspects of such concept referring to its application to the world of construction. Issues spanning from history, form-finding and morphology, structural behaviour...


Workshop di costruzione architettonica: l’interazione tra forma e struttura nella ricerca e didattica del progetto

Pugnale, Alberto, Deregibus, Carlo, Sassone, Mario & Kirkegaard

May 2011 | Conference Paper

Il rapporto che in architettura lega forma e struttura è di particolare interesse sia nella ricerca sui temi del ‘non-standard’ (Migayrou 2003), focalizzati per lo più sullo studio della gestione parametrica del progetto, sulla fabbricazione a controllo numerico dei suoi elementi, nota come File-To-Factory o più recentemente Digital Crafting, e...


On the Optimal Design of Glass Grid Shells with Planar Quadrilateral Elements

Sassone, Mario & Pugnale, Alberto

December 2010 | Article

This paper presents an optimization procedure for the solution of the planarity problem, a requirement of grid shells with four or more sides faces that need of having four adjacent nodes laying on a plane in order to use plane glass slabs as cladding elements. It can be satisfied by...


New conceptual design tools: towards designers as software customizers

Pugnale, Alberto, Holst, Malene Kirstine & Kirkegaard, Poul Henning

November 2010 | Conference Paper

This paper aims to discuss recent approaches in using more and more frequently computer tools as supports for the conceptual design phase of the architectural project. The present state-of-the-art about software as a conceptual design tool could be summarized in two parallel tendencies. On the one hand, the main software...
