Timber-framed wall buildings are seen all over Europe, especially in seismic regions, given its adequacy to resist earthquakes. The “Pombalino” buildings, developed after the great 1755 earthquake that destroyed Lisbon, constitute one of the best examples of historic seismic-resistant structures based on timber-framed masonry walls. The research presented in this article aimed at experimentally evaluating the seismic behavior of the “Pombalino” buildings. The experimental program was based on extensive dynamic testing on sub-structures of typical “Frontal” walls (the timber masonry walls), carried out at the LNEC (the Portuguese National Laboratory of Civil Engineering) shaking table. The tests comprised (a) seismic tests, in which the seismic action was applied with increasing amplitude in one direction; and (b) dynamic identification tests, aiming at evaluating the dynamic properties of the sub-structures and their evolution with damage accumulation. 相似文献

This study examines the socio-spatial practices of the United June Movement (UJM), a grassroots movement that drew inspiration from the neighbourhood forums of the Gezi Park protests. We argue that the counter-sites of politicisation and symbolic places engraved on the social movements’ memory formed the socio-spatial base of solidarity networks and the long-term political organising of UJM. Secondly, we suggest that in an authoritarian context, activist organisations nourishing from full-scale protests such as UJM need to form, reshape, and sustain free spaces where they feel protected. For testing these arguments, we designed fieldwork around UJM with an ethnographic approach. We concluded that the desire for social change has the potential of generating alternative visions in a spatiotemporal context, but in the medium term, it can turn into a feeling of self-enclosure or being besieged. Even so, such attempts leave a perpetual legacy, tagged to certain spaces and geographies. 相似文献

Salt crystallization is a major cause of degradation in old buildings. One of the issues that stills need clarification is regarding the influence of the salts on the capillary absorption and subsequent drying of porous building materials. This article presents an experimental study that included capillary absorption and evaporative drying tests on two types of material (lime mortar and ceramic brick) using pure water or saturated solutions of six salts (sodium chloride, sodium sulfate, sodium nitrate, sodium carbonate, potassium nitrate, or potassium carbonate). The results of capillary absorption agree only roughly with the linear relationship, predicted by theory, between sorptivity and the square root of the ratio between viscosity η and surface tension σ of the solution (σ/η)1/2. This poor agreement is probably due to material heterogeneity. The drying dynamics was regular and showed little dispersion between specimens, but only for the uncontaminated materials. Indeed, the drying dynamics of the salt contaminated materials was often irregular or diverged among similar specimens, and the same happened with their salt decay patterns. The main conclusion is that soluble salts can amplify the effects on drying of the small structural heterogeneities that porous building materials normally depict. 相似文献

The history of cross vaults began almost 2,000 years ago with a widespread use during the Middle Ages and Renaissance, becoming nowadays one of the most diffused and fascinating structural typologies of the European building cultural heritage. However, conversely to the undeniable excellence achieved by the ancient masons, the structural behavior of these elements is still at the center of the scientific debate. In this regard, with the aim of reviewing the knowledge on this subject as a concise and valuable support for researchers involved in conservation of historical buildings, with a focus on design rules and structural analysis, the present study firstly introduces the cross vaults from a historical perspective, by describing the evolution of the main geometrical shapes together with basic practical rules used to size them. Then, the article deals with the subsequent advancements in structural analysis methods of vaults, until the development of modern limit analysis. 相似文献

This article aims to analyse the importance of the Egyptian campaign to Ottoman policy in the First World War. It seeks to add to our knowledge of the Ottoman war experience by putting the focus on the empire’s preparations for conquering Egypt and by giving priority to understand the aims of the expedition. The expedition itself is placed within the context of the jihad policy adopted at the beginning of the war and which sought to put an end to the Entente’s colonial domination of Muslim countries. The Ottomans’ propaganda initiatives in support of the measures were meant to motivate support among the Syrian population through the idea of holy war. 相似文献

Although higher education in Turkey does not have especially well-advanced systems and resources for addressing graduate employability, two developments are making it particularly important for Turkish geography departments to give increased priority to this agenda. One is the country’s new Higher Education Qualifications Framework and the other is a major increase in geography student numbers, which means that geographers seeking school teaching posts (traditionally seen as the natural career pathway) now hugely outnumber the posts available. Against this background, this paper proceeds to explore the potential of geographic information systems (GIS) to contribute to geographers’ employability in Turkey through a study involving the views and experiences of academic staff, students and employers. The paper reveals a mixed picture of both opportunities and challenges. It ends with a series of employability recommendations for geography and GIS in Turkey, a number of which could also be of wider relevance elsewhere. 相似文献
