Fenomenologia estrutural da dupla curvatura no processo de ideação arquitetónica

Abstract

O elevado valor plástico e a eficiência estrutural intrínseca das formas curvas contrasta paradoxalmente com a sua parca utilização na arquitetura, não tirando proveito das suas potencialidades e tornando-a mais pobre espacialmente. A maior complexidade destas formas, exige por sua vez um maior domínio da geometria, da fenomenologia estrutural e dos processos construtivos, impondo uma visão holística e interdisciplinar, que resulte num processo dialético entre a conceção e a construção. As ferramentas digitais deviam constituir um quadro tecnológico capaz de acolher e responder a estas questões, designadamente da produção das superfícies curvas. Esta realidade emergente exige um processo cognitivo e metodológico, que importa refletir, quer na prática profissional, quer no ensino da arquitetura. As teorias de projeto digital e os seus esquemas taxonómicos, estão longe de refletir as necessidades operativas e teóricas da prática de projeto. Embora intua a sua importância na prática do arquiteto, a sua abordagem é ainda de grande abstração, a um nível semiótico. O trabalho ora produzido recorre a um conjunto de axiomas e teoremas operativos para constituir uma metodologia de carácter funcional, que tem a criatividade como capacidade operativa máxima. A tecnologia construtiva que emerge do pós-guerra regida pela necessidade de baixo custo e rapidez, resulta em sistemas construtivos lineares, inábeis em lidar com a conceção e manuseamento da geometria curva e com a personalização. Esta lacuna foi o pretexto para o desenvolvimento do sistema construtivo Brick-Warp. O sistema referido recorre a peças produzidas em série, personalizadas à posteriori por processos de fabricação digital, juntando a produção em série com a personalização em série. A isto acresce um processo de montagem que recorre ao pré-esforço para estabilizar as peças, dispensando a utilização de cibramento. O que torna o sistema construtivo, pensamos, especialmente competitivo. O trabalho desenvolvido consegue abarcar na sua aproximação ao problema, tanto a a dimensão teórica como a dimensão construtiva, originalidade essa que, pensamos, fortalece a proficiência das proposições apresentadas.

ABSTRACT: The inherent structural efficiency of curved shapes and the eminent value of their plasticity contrasts paradoxically with its sparse use in Architecture. This situation prevents the whole subject matter of profiting from this area of great potential, thus rendering it less rich in terms of spacial analysis and use. The greater complexity of these shapes demands in turn a greater mastery of Geometry, structural phenomenology and correspective building processes, imposes a holistic and therefore interdisciplinary approach which results both in and from a dialectal process between conception and construction. The digital tools should make up a technological framework capable of responding to these questions, namely of the creation of curved shapes. The reality demands a cognitive methodology which reflect this, wether in architectural pratice or teaching. Theories for digital processing and their taxonomic schemes are far from reflecting the operational and theoretical demands regarding of project practice. Although it is important in the architect's practice, his approach is still of great abstraction. The present dissertation resorts to a set of principles and theorems to build a functional methodology which holds creativity as its top operating capability. Constructive technology emerging from the post war era, governed by the need for low cost and speed derived into linear constructive systems, inapt to dealing with the design and handling curved geometry or customizing and personalization. This gap was the pretext for the development of the Brick-Warp system. The given system resorted to parts which were mass produced and later personalised by digital fabrication, marrying mass production to mass personalisation. An assembly procedure is then used resorting to pre-stress in order to stabilize the parts thus dismissing the need to apply scaffold. It is these features that will ultimately make the system, we think, specially competitive. The work now completed, encompasses both the theoretical and the constructive dimensions of the problem, the originality of which, we think, strengthens the proficiency of the propsitions now presented.
