Reciprocal systems based on planar elements: morphology and design explorations

Baverel, Olivier & Pugnale, Alberto

September 2013 | Conference Paper

The concept of transferring forces in a reciprocal way has always been related to the use of elongated timber elements. However, planar components can also be considered - circular tiles, squares, triangles and more articulated or irregular geometries are all valid alternatives. This paper proposes an initial study on reciprocal...

Multi-Objective Optimization of Concrete Shells

Méndez Echenagucia, Tomas, Pugnale, Alberto & Sassone, Mario

July 2013 | Conference Paper

This paper discusses the application of a Multi-Objective Search method to the design of shell structures. Contrasting objectives of lightweight and high stiffness are considered for two case studies with different geometry and constraints. The Multi-Objective search is performed in the frame of the Pareto theory of non-domination, implemented in...

Computational Morphogenesis in architecture: structure and light as a multi-objective design/optimization problem

Liuti, Alessandro, Pugnale, Alberto & Erioli, Alessio

July 2013 | Conference Paper

This paper deals with a multi-objective design/optimization grid-shell problem. Structural behavior and light absorption/shading have been selected as fitness functions. Such performance criteria can separately lead to different and divergent optimal solutions but, if they are considered as a whole, they are expected to result in several equivalent or similar...

Reciprocal systems based on planar elements

Baverel, Olivier & Pugnale, Alberto

July 2013 | 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 design potential. Reciprocal structures were first originated as assemblies of elongated elements. In Europe, the concept of spanning longer distances than the...

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...
