Southern Modernisms. Critical Stances through Regional Appropriations. Conference proceedings

The hegemonic definition of Modernism has been subjected to an intense critical revision process that began several decades ago. This process has contributed to the significant broadening of the modernist canon by challenging its primal essentialist assumptions and formalist interpretations in the fields of both the visual arts and architecture. This conference aims to further expand this revision, as it seeks to discuss the notion of “Southern Modernisms” by considering the hypothesis that regional appropriations, both in Southern Europe and the Southern hemisphere, entailed important critical stances that have remained unseen or poorly explored by art and architectural historians. In association with the Southern Modernisms research project (FCT – EXPL/CPC-HAT/0191/2013), we want to consider the entrenchment of southern modernisms in popular culture (folk art and vernacular architecture) as anticipating some of the premises of what would later become known as critical regionalism. It is therefore our purpose to explore a research path that runs parallel to key claims on modernism’s intertwinement with bourgeois society and mass culture, by questioning the idea that an aesthetically significant regionalism – one that resists to the colonization of international styles and is supported by critical awareness – occurred only in the field of architecture, and can only be represented as a postmodernist turn.

Southern modernisms from A to Z and back again

The book now being published results from a research project entitled Southern Modernisms that ran from March 2014 to May 2015 with FCT funding. The aim of the project was to explore the possibility of constructing a more inclusive, plural notion of modernism through the revision of Modernism’s prevailing definition – its stylistic focus, its formalist and anti-representative bias, as well as its autonomic assumptions, or, as far as architecture is concerned, its functionalist credo. This critical undertaking was grounded on the hypothesis that southern European modernisms featured a strong entrenchment in popular culture (folk art and vernacular architecture), and that this characteristic could be understood as anticipating some of the premises of, what would later become known as, critical regionalismo.

Historical reconstructions of raw materials based on a blue smalt coating applied to a seventeenth-century altarpiece

Based on samples cross-sections from the Main Altarpiece of the Coimbra Old Cathedral, where a blue coating performed in 1685 is observed (that was partly covered with a Prussian blue-containing overpaint), the raw materials present in this coating were reproduced and studied. Blue areas were painted with smalt in oil, according to the contract signed by Manoel da Costa Pereira in 1684 and the analysis by Le Gac in 2009. Based on these, three batches of cobalt-based glasses (S1, S2 and S3) were heated and melted in alumina crucibles in the kiln. S1 contained 6.03 % of cobalt oxide, S2 contained 2.10 %, with the addition of 1.49 % of magnesium oxide, and S3 contained 6.82 % of cobalt oxide, with the addition of 4.63% of antimony trioxide. These batches were ground mechanically with water and manually with different vehicles stated in recipes. The results were studied by means of OM, SEM-EDS, X-Ray CT, Colorimetry and Vickers HT. Different binders were also produced and analyzed by means of μ-FTIR, in order to perform their characterization and obtain Standard Spectra. Since anhydrite was identified in the ground layers, gypsum from Óbidos was also characterized by XRD. The main goal of this thesis was to study all the raw materials present in the 1685-blue coating, in order to allow the historically accurate reconstruction of the layers build-up in the next future.

Geopolymers as infill material for conservation of azulejos

The restoration materials currently used to fill gaps in architectural historical azulejos (e.g. lime or organic resin pastes) usually show serious drawbacks in terms of compatibility, effectiveness and durability. The existing solutions do not fully protect azulejos in outdoor conditions and frequently result in further deterioration. Geopolymers can be a potential solution for azulejo lacunae infill given the chemical-mineralogical similitude to the ceramic body, and also the durability and versatile range of physical properties that can be obtained through the manipulation of their formulation and curing conditions. This work presents and discusses the viability of the use of geopolymeric pastes to fill lacunae in azulejos or to act as “cold” cast ceramic tile surrogates reproducing missing azulejo fragments. The formulation of geopolymers, namely the type of activators, the aluminosilicate source, the amount of water (to meet adequate workability requirements) and curing conditions were studied. The need for post-curing desalination was also considered envisaging their application in the restoration of outdoor architectural historical azulejos frequently exposed to adverse environmental conditions. The possible advantages and disadvantages of the use of geopolymers in the conservation of azulejos are also discussed. Several techniques were used to study the chemical and physical behavior of geopolymers, namely FT-IR, XRD, MIP, SEM-EDS, WDXRF, electrical conductivity, open porosity, bending strength, adhesion strength, water vapour permeability, thermal expansion and hydric expansion. The results indicate that geopolymers are a promising material for restoration of azulejos, exhibiting some properties, such as adhesion to the ceramic substrate, higher than inorganic materials used nowadays, such as aerial lime based pastes.

Entre o Vernáculo e o Híbrido: Concepções da Arquitectura Popular Portuguesa entre 1960 e 2000

A antropologia e a arquitectura são disciplinas que se têm frequentado com alguma assiduidade, algumas vezes de forma consciente, outras sem que disso se tenham necessariamente dado conta. Uma das mais assíduas plataformas de encontro entre ambas as disciplinas tem sido fornecida pela arquitectura variavelmente designada de “popular”, “vernácula” ou “tradicional”. Por vias diferentes, sobretudo no decurso dos anos 1960, tanto a antropologia como a arquitectura fizeram da arquitectura popular um objecto comum de estudo, analisado de acordo com uma preocupação dominante por formas genuínas e autênticas, marcadas pelo peso da tradição. E por vias diferentes, tanto a antropologia como a arquitectura, retendo embora uma preferência pelo popular, trocaram, a partir dos anos 1980, essas ideias de genuinidade e autenticidade por uma conceptualização do popular enquanto matéria híbrida e impura. Learning from Las Vegas (1977) de Robert Venturi, do lado da arquitectura, e Culturas Híbridas (1989) de Nestor García Canclini, do lado da antropologia, são duas obras marcantes nessa viragem. É a partir delas que esta comunicação se propõe interrogar o modo como no Inquérito à Arquitectura Popular em Portugal se pode surpreender uma tensão entre o popular como autêntico e formas mais misturadas do popular, resolvida então a favor da autenticidade, que se projecta, de forma contraditória, na actualidade.

Implementation of a probabilistic based framework for safety assessment of existing timber elements

The assessment of existing timber structures is often limited to information obtained from non or semi destructive testing, as mechanical testing is in many cases not possible due to its destructive nature. Therefore, the available data provides only an indirect measurement of the reference mechanical properties of timber elements, often obtained through empirical based correlations. Moreover, the data must result from the combination of different tests, as to provide a reliable source of information for a structural analysis. Even if general guidelines are available for each typology of testing, there is still a need for a global methodology allowing to combine information from different sources and infer upon that information in a decision process. In this scope, the present work presents the implementation of a probabilistic based framework for safety assessment of existing timber elements. This methodology combines information gathered in different scales and follows a probabilistic framework allowing for the structural assessment of existing timber elements with possibility of inference and updating of its mechanical properties, through Bayesian methods. The probabilistic based framework is based in four main steps: (i) scale of information; (ii) measurement data; (iii) probability assignment; and (iv) structural analysis. In this work, the proposed methodology is implemented in a case study. Data was obtained through a multi-scale experimental campaign made to old chestnut timber beams accounting correlations of non and semi-destructive tests with mechanical properties. Finally, different inference scenarios are discussed aiming at the characterization of the safety level of the elements.
