ABSTRACT

The vulnerability of masonry infills within reinforced concrete (rc) frames under out-of-plane loading induced by earthquakes has been observed in several past earthquakes through severe damage and often total collapse. Although the infill panels are assumed as non-structural elements, their damage or collapse is not desirable, given the possible consequences in terms of human life losses and repair or reconstruction costs.

Therefore, it is important to gather better insight on the out-of-plane behavior of existing infills so that strengthening guidelines can be derived. In this scope, the main objective of this study is to analyze the out-of-plane experimental behavior of masonry infilled frames that are characteristic of Portuguese buildings and can be seen in other south European countries. In the experimental study carried out, different parameters affecting the out-of-plane response of infilled frames were considered, namely, workmanship, existence of openings and prior in-plane damage. The experimental program was designed to test six half-scale specimens. The out-of-plane loading was applied uniformly to the brick infills by means of an airbag to simulate the effect of earthquakes.  相似文献

In the second half of the 19th century, the area known as Lezíria, in Portugal, started to use portable steam and traction engines in agricultural production. Out of more than a hundred original examples, all of them manufactured in England, little more than a dozen survive today, with different levels of preservation. This article studies these for the first time through an archaeological perspective, identifying their use and importance in different agricultural activities in the production of goods such as olive oil.  相似文献

This paper is the first updated review of the scope, depth and problems related to the current radiocarbon chronology of the late prehistory of southern Iberia. The aim is twofold. First, it critically analyses the quantity and quality of radiocarbon dates used to interpret the diverse trajectories of western Mediterranean societies throughout more than four millennia. Secondly, it reviews a set of three different and prominent archaeological phenomena from an inter‐regional comparative perspective: primary and secondary burial practices, domestic stone architecture and ditched enclosures. Our long‐term, geographically wide‐ranging approach locates similarities while highlighting the effects of local and historical conditions in certain divergent circumstances.  相似文献

Research into the Chalcolithic period in the region of Lower Estremadura, south of Torres Vedras, western Portugal, has generated much new data from fortified sites and cemeteries. The lack, so far, of a thorough overview of this diverse body of information has hindered the definition of the Chalcolithic culture of the region. The economic, social and cultural transformation observed at sites with a long sequence beginning with the Late Neolithic, has never been analysed.
The results obtained by the author in one of the most notable sites of the region, the fortified site of Leceia, near the town of Oeiras, are of particular interest. Seventeen excavation campaigns carried out since 1983 have provided a remarkable body of information. The characterization of other previously identified Chalcolithic groups in Portugal allow us to see how the Chalcolithic of Estremadura relates, at a regional level, with the cultural development to the north, the south, the hinterland and the coast.
Of major importance to this discussion are the chronometric results obtained in Leceia. For the first time, the 36 radiocarbon dates and their subsequent statistical treatment have allowed us to establish absolute boundaries for the existing successive cultural phases of the Late Neolithic and the Early, Middle and Late Chalcolithic.  相似文献

Abstract

This review analyzes, through three recently published books that talk about cultural heritage in Latin America, how the Cultural Heritage Studies have allowed us to understand the current situation in the region characterized by the growing tendency to promote declarations of heritage as part of a plan for the use of culture as a resource for sustainable development. Likewise, those books analyze how responses from local communities are generated to hegemonic definitions of heritage, which indicates that cultural heritage in Latin America is not something given but something in constant construction and dispute.  相似文献

Drawing on ethnographic material collected in Bahia (Brazil) between 2004 and 2011, this article presents an alternative account of the notion of ‘filiation’ that avoids the equivoques concerning this concept that are dominant within contemporary anthropological discourses on kinship. The story of a lay preacher whose faith responds to her lack of a father figure illuminates how the constitution of personhood is based on filiation as a triangulation.  相似文献
