This paper presents a project designed and built for the Seventh World Urban Forum (WUF7) in Medellín, Colombia, commissioned by the Department of Habitat of the United Nations (UN-Habitat).
The project is a " free-form " masonry shell, built using the technique of thin-tile vaulting (also known as Catalan or Guastavino vaulting). UN-Habitat inten...
The structure of the concrete floor presented in this paper consists of a thin funicular vault, quadrilateral in plan, supported on its four corners, and stiffened by a system of " ribs " walls on its extrados. The structural prototype is completed with tension ties, which link the supports and absorb the horizontal thrusts of the funicular shell....
The project “Brick-topia” was based on a combination of the latest structural analysis and form-finding computational tools with traditional, cheap and effective construction techniques. It is the result of innovation to fight against budget and time. The initial budget was 3,000 euros and only seven weeks was the time to look for sponsors, design...
This article introduces a methodology for a novel data-driven computational model aimed at aiding public administrations in managing and evaluating the adaptative reuse of buildings while tackling ecological and digital challenges. Drawing from the 2030 Agenda for Sustainable Development, the study underscores the significance of innovative approac...
This article examines the involvement of Portuguese architect Álvaro Siza in the reconstruction of West Berlin, specifically in the project of the Bonjour Tristesse block in the Kreuzberg neighborhood between 1982 and 1988. The study investigates the urban and social context of the time, marked by post-war tensions and neighborhood mobilizations, w...

Conventional formworks for concrete curved shells either are expensive, complex and wasteful or have formal restrictions. Using tile vaults (also known as timbrel, Guastavino, thin-tile or Catalan vaults) as stay-in-place formwork for concrete shells could significantly reduce construction costs and material waste. Tile vaults only require formwork...
The complex structural behaviour of masonry, with its brittle response in tension, frictional response in shear, and anisotropy, makes it challenging to model accurately. Tile vaults, with their unique features such as different binders and bricks placed flat, have distinctive structural performance, and determining the most suitable assessment met...
The celebration of the European Year of Architectural Heritage in 1975 in Amsterdam had a great impact on architectural debate in West Berlin, which held a similar event one year later entitled A future for our past. There was a climate of great tension in the city between the precursors of the urban development plans and the social movements in th...
Cities face the challenge of transforming existing buildings to be reused, particularly those that are underused or not used at all. Tackling this issue, the European Commission approved in 2014 a package of measures to promote a circular economy. According to this agreement, our cities can be more sustainable and resilient by transforming these un...
La crisis sociosanitaria desencadena-da por la pandemia viral de la Covid-19 ha agraviado las consecuencias provocadas por las carencias habitacionales de la ciudad y también las grandes dificultades que encuentra el emprendimiento local para crecer en Barcelona. También, la emergencia actual, ha dejado en segundo término, la lucha contra el cambio...
Tile vaults are unreinforced masonry structures made of thin bricks (tiles) and fast-setting mortar that can be constructed without the need of a formwork, except at the boundaries, making them inherently economic. Their slenderness and finishing make them also efficient and expressive. These qualities of tile vaulting can be enhanced by combining...
The Extended Limit Analysis of Reinforced Masonry (ELARM) is a simple and user-friendly method for the design and structural analysis of singly-curved, reinforced tile vaults [1]. It is based on limit analysis but takes into account the reinforcement’s contribution to the composite cross-section’s bending capacity.
A three-dimensional approach to E...
Esta comunicación se propone mostrar y poner a debate la experiencia de los talleres de experimentación basados en metodologías de aprendizaje conocidas como “learning by building”. Se analiza la experiencia de los propios autores a través de un taller en el Instituto de Arquitectura Avanzada de Catallunya en el que a través de la construcción de u...
The construction of concrete shells requires formwork with rigid shuttering onto which concrete can be poured and allowed to harden. These formworks are typically complex and unique, and are frequently not reused. Furthermore, their construction is labour and material intensive, and often even requires a separate foundation. Therefore, formworks fo...
Tile vaults are traditional, unreinforced masonry structures made of thin bricks (tiles), mortar and fast-setting cement or gypsum. They can be constructed without the need for a formwork, except at the boundaries, making them inherently economic. Tile vaults have historically provided a solution for the efficient construction of vaulted structures...
Tile vaults are unreinforced masonry structures made of thin bricks (tiles) and fast-setting mortar that can be constructed needing only formwork along their boundaries, making them inherently economic. Their slenderness and finishing make them also efficient and expressive.
These qualities of tile vaulting can be enhanced by combining it with conc...
This paper describes the concept, form finding, fabrication and experimental testing of a prototype floor system, derived from principles of shallow arching action, to initiate internal compressive stresses rather than exclusively flexural stresses. This vaulting in a floor system leads to a lightweight structural element, with significant weight s...
New interactive equilibrium methods for the design and analysis of masonry structures have facilitated the construction of masonry structures with a formal language well beyond what is typically associated with compression-only architecture. These developments have also rekindled interest in tile vaulting, and led to a rediscovery of this tradition...
Reinforced-brick shell structures are mainly known through the extraordinary work of the Uruguayan engineer Eladio Dieste. However, other remarkable examples of shells in reinforced masonry were being built during Dieste´s development of the technique or even before. The works by Guillermo González Zuleta in Colombia and Ildefonso Sánchez del Río i...
"The conservation and restoration of monuments must have recourse to all the sciences and techniques which can contribute to the study and safeguarding of the architectural heritage " [1].
The Venice Charter showed a new understanding of historical constructions' conservation. In particular, the way that it is defined in the first two articles wid...
La cultura del usar y tirar ha imperado en los últimos tiempos y el culto a lo nuevo ha transformado también la arquitectura. Del mismo modo en que se descartan productos de consumo que todavía funcionan por los nuevos modelos, se planifican barrios completamente nuevos sobre suelos no urbanizados que provocan la expansión de las ciudades en forma...
Hundreds of years support the effectiveness and efficiency of some traditional building techniques which solved architectural aspects of housing, as well as other tiypologies. Tile vaulting, or "volta catalana", appeared in Spain as we know it today five centuries ago. It consists on the construction of vaulted structures of different geometries wi...
