Nous avons déjà commencé à parler des outils des conception que nous utilisons dans notre travail. Par la suite nous allons focaliser le discours sur le rôle des différents outils et logiciels.

Dans notre démarche quotidienne, une maquette virtuelle 3D (Rhinoceros ou Autocad) est développée à partir des premiers croquis réalisés normalement à la main. Le logiciel Rhinoceros représente aujourd’hui un véritable phénomène dans le monde de l’architecture. Conçu à la base pour les métiers du design d’objets (en particulier pour le dessin de bijoux) le logiciel s’est transformé dans les cinq dernières années en un véritable standard pour les agences d’architecture. La raison de ce succès est principalement liée à la grande facilité de générer, décrire et modifier des formes complexes.

This article presents a new methodology for generating compression-only vaulted surfaces and networks. The method finds possible funicular solutions under gravitational loading within a defined envelope. Using projective geometry, duality theory and linear optimization, it provides a graphical and intuitive method, adopting the same advantages of techniques such as graphic statics, but offering a viable extension to fully three-dimensional problems. The proposed method is applicable for the analysis of vaulted historical structures, specifically in unreinforced masonry, as well as the design of new vaulted structures. This paper introduces the method and shows examples of applications in both fields.

1. INTRODUCTION

Medieval vault builders created complex forms carefully balanced in compression. The structural properties of these sophisticated forms are still poorly understood because of a lack of appropriate analysis methods, i.e. methods relating stability and form. Understanding the mechanics of these vaulted structures leads to new insights for both analysis and design.

DEFINITION. Forms are called ‘developable’ or ‘single curved’ when they can be created through ordinary bending of a planar surface without stretching, cutting or wrinkling the material. These surfaces are characterized by only bending in one direction at a time, like the cylinder or the cone. Developable surfaces are useful because they allow round forms to be made out of flat materials like plywood, sheet metal or cloth. This is why they are used for ship building, tent sewing and fabrication of ventilation ducts etc.

Complexitys blog was conceived amid much brainstorming and deliberation, and with much enthusiasm, but with little idea of exactly which direction it would proceed in. Little more than two months after its birth and we’ve been surprised and encouraged to see the first important result of our devotion to, and investment in, an open online communication of architecture.
As Domenico Di Siena from Ecosistema Urbano Office explained in our “web for architects” training in Paris, “an architecture office’s blog is not a portfolio or a place to talk about themselves, but rather an incredibly powerful tool to create a community around the office’s activities and interests”.
Two months into the project and several blogs worldwide have begun talking about complexitys, so these words are now becoming reality.

Bueno. Este es un post de viernes por la tarde, es decir un poco de risa.
Pero quizás tampoco mucho.
También es el primer post en español, y también es el primer post de la categoría “Architecture Games”, en la cual vamos a hablar de todo lo que está relacionado con la parte más creativa y de juego de la arquitectura y de la construcción.

We are happy to post our first entry of our new DOWNLOADS category.
Like a small but growing number of other architecture offices (such as Ecosistema Urbano and Arquitextonica), we believe that sharing content can be useful, productive and not anti-economic.
In other words, we believe in an Open Culture.

That’s why on this post we want to share with you in a free download format, a rhinoscript code (see video above) that we developed for a skylight design in China, which can help with understanding the concept of double and single curvature geometry.
If you are new to rhinoscript, it may help you to have a look at THEVERYMANY, where you will get a better idea of what can be achieved within this format.
