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...

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...

The church of Longuelo designed by Pino Pizzigoni. An unknown example of outstanding structure

Deregibus, Carlo & Pugnale, Alberto

September 2009 | Conference Paper

This paper presents a critical study of the church of Longuelo, Italy, designed in 1966 by Giuseppe (Pino) Pizzigoni (1901–1967), an Italian architect who lived and worked in the city of Bergamo. He began his studies on shell structures in the Fifties and many of his buildings show outstanding skills...

Applications of a “Virtual” Force Density Method

Basso, Paolo, Del Grosso, Andrea, Pugnale, Alberto & Sassone, Mario

September 2009 | Conference Paper

The Force density Method [FDM] has been well known - since Linkwitz and Schek's first development in 1970's - as a powerful tool for analytical form-finding and static analysis of self-stressed structures like tensile membranes and cable networks. Actually, force density is always associated to a real stress state of...

Computational morphogenesis in architecture: the cost optimization of free form grid-shells

Basso, Paolo, Del Grosso, Andrea, Pugnale, Alberto & Sassone, Mario

September 2009 | Conference Paper

In this paper, an optimization problem related to the tessellation of a free form grid shell is presented. This kind of structures is generally composed by a supporting grid that defines the geometry of a large number of cladding elements always different one from another. From the constructive point of...

Shape Optimization of free form grid-shells

Basso, Paolo, Del Grosso, Andrea, Pugnale, Alberto & Sassone, Mario

May 2009 | Conference Paper

In this paper, we present two different optimization procedures, developed and implemented to deal with economic and constructive problems of free form grid shells. This kind of structures is generally composed by a supporting grid that defines the geometry of a large number of cladding glass elements always different one...

Optimal design of glass grid shells with quadrilateral elements by means of a genetic algorithm

Sassone, Mario & Pugnale, Alberto

May 2008 | Conference Paper

In this paper, a constructional problem related to grid-shells design is approached as an optimisation problem and an evolutionary solution technique is proposed. The construction of glass grid-shells, when only four sides cladding elements are used, requires to check the planarity of each element, it means that the four corner...

On the interaction between architecture and engineering: the acoustic optimization of a reinforced concrete shell

Sassone, Mario, Méndez, Tomas & Pugnale, Alberto

May 2008 | Conference Paper

In this paper, a computational morphogenesis process is applied to the design and the optimization of the shell roof of a large music hall. The architectural concept is based on the folded plate technique: a set of reinforced concrete plates, connected to each other on the edges, forms the global...
