This article focuses on the effects of the earthquake which struck the Abruzzo region (Central Italy) on April 6, 2009, causing considerable damage to many ancient buildings, particularly churches. During the emergency after the earthquake, many churches and other historical monuments (towers, city walls, large town houses, etc.) were surveyed, according to first-level damage survey forms for Cultural Heritage buildings, by multidisciplinary working groups composed of experts from several Italian institutions (Universities, Ministry for Cultural Heritage, Fire Brigade, etc.). This article presents a statistical study on the information collected by the University of Padova during the surveys, which was later inserted and organized in a database, and illustrates data on damage assessment of the buildings in question. It also presents an intuitive overview of the seismic effects on several churches, allowing not only better understanding of the response of these structures to this particular earthquake, but also correlating data on it with its effects on the churches.  相似文献

ABSTRACT

Several architectural configurations of unreinforced masonry residential buildings are designed according to the different methods proposed in the Italian code: rules for the so-called simple masonry buildings, linear and nonlinear static analyses. Always complying with code requirements, for each building-site combination, the design was made, as much as possible, without an excessive margin of safety. The different design methods provided buildings with very different levels of safety, being linear static analysis largely overconservative with respect to the nonlinear static approach. These buildings were then analyzed in the companion paper.  相似文献

ABSTRACT

This research seeks to identify the factors that best explain the performance of regional innovation in Europe, in the era of smart specialization. Data were collected from the Regional Innovation Scoreboard 2016 and a quantitative methodology was followed using linear regressions as statistical methods. The results allowed us to reach four explanatory models of performance innovation for Innovative Regions Leader, Strong, Moderate and Modest. Some policies have also been suggested as possible regional innovation measures that can help policy makers to clarify and improve the innovation performance of these regions.  相似文献

The First World War is known for its use of advanced weaponry, which caused massive injuries. Over 8,000 Portuguese soldiers who had fought in the African and European theatres of war returned home with a disability. Through a qualitative analysis of archival data, newspaper articles, and legislation, this article examines what was done for these disabled veterans in Portugal between 1917 and 1927, drawing comparisons with similar situations in other countries. As it will be noted, voluntary organisations and the State took limited measures to rehabilitate disabled ex-servicemen, who were consigned to oblivion.  相似文献

A large ceramic vessel was discovered at São Brás (southern Portugal) containing a metallic hoard from the Chalcolithic/Early Bronze Age period. These weapons and tools were characterized by microanalytical techniques as being composed of copper with varying arsenic contents (2.2 ± 1.6 wt%) and minor amounts of lead, bismuth and iron. The collection shows a clear association between daggers and copper with a higher arsenic content, which can be explained by the high status of these silvery alloys. Finally, the compositional distribution of the hoard was compared with the metallurgy of the Bell Beaker and non–Bell Beaker communities inhabiting the south‐western Iberian Peninsula.  相似文献

在学术界,似乎有一个不证自明的定论,即:作为近代资本主义政治制度核心构件的议会政治是与中世纪封建社会无缘的。但事实上,在特定历史条件下,两也完全有可能联系在一起。英国由于在早期历史中形成了政治协商传统和初步成型的议会协商机制以及相应的社会化理念,从而为中世纪晚期出现议会政治奠定了必要的历史基础;但历史基础仅仅提供了议会政治早产的可能性,而将这种可能变为现实的决定性力量则是当时各种具体的特殊原因和个人因素构成的偶然机缘。换言之,中世纪晚期英国议会政治的早产是一种历史偶然现象。由此可见,偶然因素也是一种应当给予充分重视的历史决定性力量。  相似文献

This article focuses on the changes made to the cartography of southern Africa between 1725 and 1749 by the French geographer Jean Baptiste Bourguignon d’Anville. The maps in question were produced in collaboration with the Portuguese ambassador Dom Luís da Cunha as part of d’Anville’s plan to demonstrate what lay between the Portuguese colonies of Angola in the west and Mozambique in the east and to establish a link across the continent. The maps he produced in the first two phases of his mapping of southern Africa (1725–1731) echoed the traditional horror vacui. The vast blank that appeared on his map of Afrique of 1749, however, has to be seen as d’Anville intended—the integration of empty space on a map with Enlightenment rationalization of geography.  相似文献

ABSTRACT

It is an acknowledged fact that historical centers, given its significance from the cultural and architectural viewpoint, bring further challenges in terms of maintenance planning, survey, and safety assessment. The preparation of an adequate investigation plan and the extent of data to be collected is highly reliant on many aspects, such as the category of the architectonic asset, the importance of the heritage site, or the resources available, for example. In what regards the seismic response assessment of urban cultural heritage assets located in historical centers, the amount and detail of data also depend on this article, scale of assessment, and current state of conservation and occupation. Within this framework, this article provides an overview of the state of the art of investigation techniques currently used in survey operations, which are currently available for improving the knowledge level of urban cultural heritage assets within historical centers, as a supporting tool for the seismic response assessment of such singular assets. Finally, acknowledging the lack of accuracy when evaluating the seismic response of an asset enclosed in aggregate as an isolated structure, this article also focuses on the identification of the main particularities inherent to buildings enclosed in aggregate.  相似文献
