Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Pós-graduação em Música - IA; Este trabalho é uma abordagem analítica do monodrama Erwartung Op. 17 – obra do expressionismo musical composta por Schoenberg a partir do texto de Marie Pappenheim – que parte das reflexões estéticas de Theodor Adorno sobre a obra e sobre o expressionismo em geral, principalmente em sua Filosofia da Nova Música. O primeiro capítulo aborda os dois conceitos de expressão que caracterizam, na ótica de Adorno, a música anterior ao expressionismo: a expressão como simulação de paixões e a expressão como organização total da forma. Cada uma delas resultou, não obstante, em um bloqueio da expressão, decorrente da hipóstase quer seja do princípio formal abstrato, quer seja dos momentos particulares isolados do todo. Este bloqueio expressivo é desenvolvido no segundo capítulo, que aborda a dinâmica através da qual, num contexto de comercialização e fetichização da cultura, a música tende a forjar uma aparente reconciliação entre a parte e o todo, entre o universal e o singular. A música expressionista realiza uma crítica dessa aparência de conciliação e dá lugar ao singular não mediatizado pela forma. Toma...

Tese de doutoramento em Engenharia Civil / Estruturas; A preservação das construções históricas de elevado valor patrimonial é hoje um tema muito actual nas sociedades modernas tanto mais quanto estas construções desempenham um papel cada vez mais importante na indústrias do turismo e, consequentemente, na economia e na imagem e auto-estima dos países e seus povos. A perigosidade sísmica de Portugal e de muitas outras regiões do globo de que se destacam, pela sua proximidade, os países da bacia Mediterrânica, coloca um elevado número de construções históricas, nomeadamente as construções em alvenaria, particularmente vulneráveis a acções sísmicas, sob potencial risco de colapso. Pese embora a complexidade e a peculiaridade destas construções, em geral caracterizadas por uma falta generalizada de informação de que se destaca a ausência de elementos de projecto e o desconhecimento da constituição interna dos seus elementos estruturais e do seu estado actual, são as lacunas metodológicas ainda existentes no estudo destas construções, geralmente orientado por regras e procedimentos adequados para novas construções, que conduzem frequentemente a intervenções desajustadas ou desproporcionadas à dimensão dos problemas e ao valor patrimonial das construções. Além disso...

Preservation of historical constructions with high cultural heritage value is an actual theme in modern societies as these constructions play an important role in the industry of tourism and culture, and consequently in the economy and in the image of countries and self-esteem of people. The seismic hazard of Portugal and, due to its vicinity, of the Mediterranean basin puts under potential risk of damage and collapse a high number of historical constructions, namely most of the old masonry constructions, particularly vulnerable to seismic actions. The seismic behaviour of the Church of Monastery of Jerónimos, Portugal, is discussed here with a numerical simulation, using artificial seismic acceleration time histories in agreement with three seismic hazard scenarios for 475, 975 and 5000 years return periods, allowing to assess its seismic safety.

Las sociedades modernas entienden su patrimonio cultural como un hito de cultura y diversidad. Sólo durante las últimas décadas la idea de que edificios antiguos podrían ser conservados y reutilizados se ha convertido en atractiva. Sin embargo, una gran parte de este patrimonio es afectado por problemas estructurales lo cual amenaza la seguridad de los edificios y personas. Los desarrollos en el área de inspección, ensayos no destructivos, seguimiento y análisis estructural de construcciones históricas, bien como recientes normas para reutilización y conservación, permiten medidas correctivas más seguras, económicas y adecuadas. El artículo aborda las metodologías adoptadas, en diferentes casos de estudio así como presentes desafíos. En particular, intervenciones recientes en casos de estudio en Portugal (Catedral de Porto y Seminario de Braga) son analizadas con detalle.; Modern societies understand built cultural heritage as a landmark of culture and diversity.

For a long time, reactive seismic retrofitting was focused on monumental heritage and very little on vernacular architecture. In the last years, there has been a growing interest on seismic resistant design and solutions and several research units emerged to produce important research in the scientific field. However, for some time, international focus to address earthquake-damaged buildings was on intrusive techniques and technological materials to retrofit monuments. This paper aims to explore how the research project SEISMIC-V intends to fill the gap regarding this critical research problem. The research will contribute to the awareness and protection of the local seismic culture. The project outcomes will provide data for the strengthening of seismic-resistant architectural components in in-use vernacular heritage.; Fundação para a Ciência e a Tecnologia (FCT)

Specific architectural elements can be identified in vernacular constructions located in regions frequently exposed to earthquakes. Such elements are the result of a seismic culture which has been empirically developed during centuries so that the vulnerability of the buildings is reduced. This research is based on the fact that vernacular architecture may bear important lessons on hazard mitigation. Traditional earthquake resistant technologies can be successfully applied to preserve and retrofit surviving examples without prejudice for its identity. Few papers have focused on strengthening solutions emerging from vernacular architectural heritage. Research is particularly focused on case studies in Portugal where traces of Local Seismic Culture have been identified and documented through direct visual inspection, published information and local narratives. The main goal of this study is the identification and understanding of traditional construction solutions and detailing that, in many cases, have shown to improve the seismic performance of vernacular constructions.; Fundação para a Ciência e a Tecnologia (FCT)

Dissertação de mestrado integrado em Engenharia Civil (área de especialização em Perfil de Estruturas e Geotecnia); Cultural heritage buildings are structures that enclose a set of particular values which symbolically allow to become part of a given culture identity and continuity. Nowadays, the conservation interventions on these particular structures aim to retain its historic integrity, identity and symbolism by taking into account centuries of ideological evolution, related to aesthetic and technical issues. The interventions in cultural heritage buildings should only be taken after a careful analysis, which includes a diagnosis, safety assessment and the design of possible solutions. Despite the need for some conservation interventions due to lack of maintenance and progressive deterioration, situations of sudden destruction of cultural heritage buildings deserves a special reflection. A numerical model is invariably a valuable tool to assess the structural behavior of these buildings and to influence the final act decision. The present study case is the Christchurch Catholic Basilica, also known as Cathedral of the Blessed Sacrament. It is located in New Zealand and is listed as category I heritage in New Zealand – International or National significance. The four earthquakes events in an approximate period of nine months (September 2010 to June 2011) led to a progressive damage and local collapses. In order to study its structural behavior...

A procura de soluções para a gestão dos resíduos radioactivos tem sido alvo de vários estudos em vários países, ao longo de mais de 30 anos. O modelo actual preferencial para a armazenagem definitiva de resíduos radioactivos de alta actividade involve a utilização de galerias em formações geológicas de profundidade, o que obriga a estudos prévios do comportamento do solo e da flora e fauna existentes nos locais, de modo a poder prever efeitos futuros na segurança das barreiras de protecção do repositório. Apesar de os repositórios para resíduos radioactivos de baixa e média actividade não necessitarem de obedecer aos mesmos critérios que no caso dos repositórios geológicos, nomeadamente, o terem de ter em conta as altas actividades e a elevada capacidade calorífica associada àquele tipo de resíduos, também eles têm de ser cuidadosamente e profundamente estudados em todas as suas vertentes (geologia, hidrogeologia, actividade sísmica, ocupação humana, comunidades biológicas, etc.), tal como foi demonstrado no passado em relação ao repositório espanhol para resíduos de baixa e média activa, EL Cabril. O solo é um ambiente rico em termos de diversidade biológica e as bactérias estão entre os grupos mais representativos tendo...

The countries of the Middle East and North Africa (MENA) are blessed with an extraordinary cultural patrimony, secular and religious, of huge importance for each country and for humankind at large. The region is home to 48 sites already inscribed on the world heritage list maintained by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) and has an enormous nonmaterial heritage as well. The Middle East is also the cradle of the world's major monotheistic religions. This cultural patrimony is a cornerstone of many people's existence and nourishes their daily lives. It must continue to flourish. This report analyzes the cultural heritage sector in the countries of the Middle East and North Africa, and the World Bank's policy and operational experiences in this sector over the past six years, 1996-2001. It has three objectives: 1) to explore the characteristics, capacities, needs, and constraints of the region's cultural sector and their relevance to overall country development; 2) to take stock...

Modern societies understand built cultural heritage, including vernacular construction, as a landmark of culture and diversity, which needs to be protected and brought to the next generations in suitable condition. Still, a large part of this heritage is affected by structural problems that menace the safety of buildings and people. In the case of vernacular construction, deterioration due to abandonment is often present, making the phenomena of urbanization one of the most important menaces to this built heritage. The developments in the areas of inspection, non-destructive testing, monitoring and structural analysis of historical constructions, together with recent guidelines for reuse and conservation, allow for safer, economical and adequate remedial measures, as discussed in this paper; Project ‘SEISMIC - V – Vernacular Seismic Culture in Portugal’ (PTDC/ATP - AQI/ 3934/2012) , from the Portuguese Science and Technology Foundation (FCT)

Rammed earth is one of the oldest building materials in the world and is present in Portugal with a particular focus in the South of the country. The mechanical properties and the structural behavior of rammed earth constructions have been the subject of study of many researchers in the recent years. This study is part of a broader research on vernacular seismic culture in Portugal. Numerical analyzes were carried out to assess the influence of different retrofitting solutions in the behavior and seismic performance of an rammed earth building representative of the vernacular heritage of Alentejo region. Understating the structural fragilities of this type of constructions allowed determining the most appropriate retrofitting solutions.; Project ‘SEISMIC-V –Vernacular Seismic Culture in Portugal’ (PTDC/ATP-AQI/3934/2012), from the Portuguese Science and Technology Foundation (FCT)

Considering that vernacular architecture may bear important lessons on hazard mitigation and that well-constructed examples showing traditional seismic resistant features can present far less vulnerability than expected, this study aims at understanding the resisting mechanisms and seismic behavior of vernacular buildings through detailed finite element modeling and nonlinear static (pushover) analysis. This paper focuses specifically on a type of vernacular rammed earth constructions found in the Portuguese region of Alentejo. Several rammed earth constructions found in the region were selected and studied in terms of dimensions, architectural layout, structural solutions, construction materials and detailing and, as a result, a reference model was built, which intends to be a simplified representative example of these constructions, gathering the most common characteristics. Different parameters that may affect the seismic response of this type of vernacular constructions have been identified and a numerical parametric study was defined aiming at evaluating and quantifying their influence in the seismic behavior of this type of vernacular buildings. This paper is part of an ongoing research which includes the development of a simplified methodology for assessing the seismic vulnerability of vernacular buildings...

18th Society for Risk Analysis (SRA) Europe conference: From the Everyday to the Extraordinary, Karlstad, Sweden, 28th June - 1st July 2009.; Throughout the Azores' history damaging earthquakes have caused considerable physical and human losses in the archipelago. Knowing the important role that seismic risk perception can play on decisions made on earthquake risk mitigation a study (TOPOI METUS. Social cosmographies of danger. Risk perception of natural hazards) was carried out to address the Azoreans understanding of seismic risk profile, patrimonial and economic vulnerability to that risk, and risk management. Such knowledge can contribute to improve the communication of risk messages and, at a more global level, inform civil defence policies and their implementation. Based on data produced along thirty in-depth extensive interviews conducted in five of the nine islands of the archipelago, this presentation focuses on findings of perceptions regarding dimensions of risk management (i.e. information and actions taken before a crisis, and during the response and recovery phases of a disaster situation). Particular attention is given to communication aspects such as "Who do people trust?" and "What forms, strategies, and means of communication do people value most?" Preliminary results seem to point out to a generalized sense of not needing more information in order to be better prepared to face crises and to the inexistence of a culture of precaution towards major disasters. The rationales underlying those perspectives are discussed.

This paper introduces and discusses a new polarization filter which can aid interpretation of single or multichannel multicomponent seismograms. We define a measure of degree of polarization based on instantaneous polarization attributes of analytic traces. Computation of the data eigenstructure is not required and the measure can be used in combination with its spatial coherence to enhance polarized signals on seismic record sections. Our approach avoids suppressing signals with spatially changing characteristics such as happens in the transition to post-critical reflections or for reflections from laterally varying interfaces. The simplicity of the method permits the filter to be tailored to various data characteristics and the concept can be applied to cross-energy methods. We also show that non-linear amplification of rectilinearity and planarity weight functions in time-domain principal-component filters permits the size of data windows to be decreased, improving resolution and suppressing noise.; This research has been supported by the Spanish Ministry of Education, Culture, and Sport through grant SB2000-0120 and by a Marie Curie Fellowship of the European Community programme IHP (HPMF-CT-2001-01322).; Peer reviewed

The mechanical properties and the structural behaviour of rammed earth constructions have been the subject of study of many researchers in the recent years. This study is part of a broader research on vernacular seismic culture in Portugal. Numerical analyses were carried out on a rammed earth masonry construction representative of the vernacular heritage of Alentejo region. Variations in the geometry, constructive characteristics and material properties were implemented and the main conclusions of the non-linear static and modal analysis are presented. Analysing the damage framework allowed interpreting the weaknesses of this type of constructions and consider the most appropriate reinforcement methodologies.

Considering that vernacular architecture may bear important lessons on hazard mitigation, this chapter focuses on the European Mediterranean countries and studies traditional seismic-resistant architectural elements and techniques that local populations developed to prevent or repair earthquake damage. This area was selected as a case study because, as a highly seismic region, it has suffered the effect of many earthquakes along the history and, thus, regions within this area are prone to have developed a Local Seismic Culture. After reviewing seismic resistant construction concepts, a wide range of traditional construction solutions that, in many cases, have shown to improve the seismic performance of vernacular constructions of these regions is presented, as a contribution to the general overview of retrofitting building systems provided in this book. The main motivation is that most of these techniques can be successfully applied to preserve and to retrofit surviving examples without prejudice for their identity.

Given the fact that using timber frame structures has proven to improve the seismic behavior of vernacular architecture, as has been reported in past earthquakes in many countries, its preservation as a traditional earthquake resistant practice is important. This paper firstly intends to evaluate whether the use of timber frames as a traditional seismic resistant technique for vernacular architecture in the South of Portugal, traditionally a seismic region, is still active. Secondly, the city of Vila Real de Santo António was selected as a case study because it also followed a Pombaline development contemporary to the reconstruction of Lisbon. The plan included the provision of timber frame partition walls for some of the buildings and, thus, an overview of the type of constructions originally conceived is provided. Finally, the alterations done in the original constructions and the current state of the city center are described and the effect of these changes on the seismic vulnerability of the city is discussed.
