L'objectif de ces travaux est d'améliorer la compréhension de la propagation du feu à grandes échelles au sein des entrepôts de stockage en racks. L'outil numérique utilisé est FDS (Fire Dynamics Simulator), modifié pour le cas présent. Il est basé à la fois sur la résolution des équations de Navier-Stokes à faible nombre de Mach et sur les équations de conservation de l'énergie, de la masse et des espèces chimiques. Un modèle de fraction de mélange à chimie infiniment rapide est retenu pour simuler la combustion. A ceci viennent s'ajouter un modèle sur le rayonnement s'appuyant sur l'équation de transfert radiatif et un modèle de pyrolyse obéissant à une relation simple d'Arrhenius. Le modèle de sous-mailles (basé sur le modèle de Smagorinsky), est retenu pour la simulation de l'écoulement turbulent. FDS est validé par comparaison issue d'expériences de feux réalisées en espaces ouverts et confinés. Ceci permet de prévoir les caractéristiques principales du feu, telles que la hauteur de flamme au dessus du rack, la vitesse de propagation, les échanges radiatifs, convectifs, etc. Une étude préliminaire, basée sur la simulation d'une partie d'entrepôt, détermine les paramètres caractéristiques influençant la progression du feu parmi les racks tel que la hauteur du plafond. Enfin, la simulation d'un entrepôt entier sous différentes configurations, apporte des informations globales (puissances libérée par l'incendie...) sur la manière dont un feu se propage au sein d'un grand nombre de racks.

Report presents a series of analyses and recommendations for fostering the role of culture for sustainable development. Drawing on a global survey implemented with nine regional partners and insights from scholars, NGOs and urban thinkers, the report offers a global overview of urban heritage safeguarding, conservation and management, as well as the promotion of cultural and creative industries, highlighting their role as resources for sustainable urban development. Report is intended as a policy framework document to support governments in the implementation of the 2030 Agenda for Sustainable Urban Development and the New Urban Agenda.

A homage to the 1973 publication of Architecture and Utopia by Manfredo Tafuri—echoed in the title—this book is devoted to the radical experiences of the 1960s and to their consequences for the most recent developments in contemporary architecture. As a response to the profound crisis of Western culture the emerged in the 1960s, radical artists from Italy, Austria, England and Japan called into question the foundations of modernist utopias. They transmuted the difficulties of capitalism into a repertory of startling images that revealed the disturbing realities of consumer society, even in those places still resistant to the penetration of modern architecture, such as Superstudio and Archizoom’s Florence. Their model, though exhausted in the space of experimentation, went on to inspire a generation of architects, from the High Tech movement to Rem Koolhaas, who sought to employ the paradigm of dystopia as both a visionary and a constructive method, one which could operate on the architecture of late capitalism and generate unexpected possibilities for urban planning. In the light of these examples, how to define a unified “dystopian” method of design, i.e. a common ground for an architecture that, by its very nature, seems to resist systematization? Are the most recognizable architectural expressions of this theoretical framework—characterized by brazen displays of technology and structures of overwhelming scale—merely isolated cases, albeit of particular iconic power? Or do they belong to a wider landscape of antirational architectural projects? And to what extent are these disturbing expressions premised on the utopian tradition or, better yet, the conceptual model of “negative thought”? The goal of this book is to respond to such questions, thus initiating an open dialogue about the legitimacy of this critical category.

What is the nature of the interaction between architecture and machines as key objects in human design, and how does this interplay work? The contributors to this book explore this multifaceted interchange in its broad thematic manifestations and historical depth, focusing above all on three aspects: machines that assist in the design and construction of buildings, those that perform their tasks inside the walls and structures of buildings, and--in particular--machines that act as models and images of architectural thought. What emerges is that the subject of machines within the architectural framework has been rooted not simply in concrete technical questions, but rather to a far greater extent in general programs, processes, and performances, and thus in fundamental categories of built space. As the first issue of gta papers, Architecture / Machine forms the basis of a new publication format of gta Verlag. The gta papers will, at regular intervals, encompass and present current and selected research findings from ETH Zurich's Institute for the History and Theory of Architecture.
