Abstract

St Pancras station has provoked controversy and shaped opinions throughout its existence. In reactions to its construction and changing views on its architectural style, from its decline in the 1930s to the debates over its future, and in the spectacular reversal of fortunes that has made it at once the symbol of the railway renaissance and an exemplar of how great historic buildings handled with care and understanding can effect our wider sense of values, St Pancras has been profoundly infl uential. Throughout, the impact of St Pancras has been more far-reaching than its role as a railway terminus. These are the trends that are explored in this paper.  相似文献

The main objective of this work is to assess the vulnerability and seismic risk of typical existing modernist unreinforced masonry (URM) modernist buildings and aggregates situated in the Eixample district of Barcelona, part of the architectural heritage of the city. The context of the analysis is the methodology proposed by the Risk-UE project. The buildings are characterized by their capacity spectrum and the earthquake demand is defined by the 5% damped elastic response spectrum, considering deterministic and probabilistic earthquake scenarios. A discussion addresses the basis of the seismic damage states probabilities and the calculated damage index. An important research effort has been focused on the buildings modeling. All the architectural elements and their mechanical properties have been studied and evaluated accurately. It has been evidenced that a detailed and complete knowledge of all the structural elements existing in this type of buildings influence directly their behavior and hence the calculations and the results. The analysis of the isolated buildings and of the aggregate building has been performed for both mentioned seismic scenarios. Finally, a complete discussion of the results is included.  相似文献

SUMMARY: This essay examines the available archive of articles on standing buildings published in Post-Medieval Archaeology. After setting out some general trends evident in a brief analysis of the number of buildings archaeology articles published over the last 50 years, their subjects and authors, this essay places these articles in three key wider contexts: the relationship of buildings archaeology to architectural history; buildings archaeology in Post-Medieval Archaeology in an international context; and the Society for Post-Medieval Archaeology’s relative lack of engagement with modern buildings and contemporary built heritage.  相似文献

When structural retrofitting of buildings is required due to seismic safety considerations, building owners or government officials are faced with a crucial decision whether to demolish and rebuild their buildings, or retrofit them. Simple decisions based on fixed proportions, such as demolish and rebuild if retrofit costs exceed 40% of the replacement cost, may be misleading. A financial analysis should be carried out considering all the revenues and costs of the building during its life time. A low-cost residential apartment building that has a construction cost of $140/m2 is selected in this study to represent the vulnerable buildings in developing countries under seismic risk. Life-cycle cost analysis approach is employed to value the rebuild or retrofit alternatives to compare economically. Economic assessment has been carried out for various parameters. It has been found that the age of the building and the retrofit ratio are dominant parameters among the others. The critical retrofit ratio (percent of retrofit cost to initial construction cost) varied from 25% for 40 year old buildings to 67% for 10 year old buildings. It is suggested that economical decisons should not be made simply by comparing the retrofit costs to initial construction costs.  相似文献

Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas (‘beautiful stones’) found in some of them, and their relation to certain artistic trends in so‐called Celtic art.  相似文献

A new approach has been developed for finding optimal location of sensors in 3D multi-storeyed buildings. This approach is based on the compact probabilistic representation of acceleration response in terms of its covariance matrix. For a specified number of sensors, the optimal location has been taken to be the one for which the computed covariance matrix is closest to the exact covariance matrix of the random field constituted by the acceleration response process. It has been found that the determined sensor locations match favourably with those predicted by earlier studies for the special case of shear buildings. Further, the optimality of the determined sensor locations has also been verified by identifying the system parameters from the time series data and comparing them with those of the Finite Element Model.  相似文献

A data base containing details of all the published Anglo-Saxon buildings constructed in timber has been created in the course of previous work. In this paper, a systematic analysis of the contents of the data base is presented with particular reference to regional differences in the buildings and their chronological development. From this, spatial and temporal patterns of evolution of the buildings are determined, and are briefly compared with those of Anglo-Saxon culture as a whole.  相似文献

Following international trends, Turkey has recently introduced decentralisation reforms to its highly centralised public administration system. These reforms have also applied to the cultural heritage sector, where innovative laws since 2004 have allowed local administrations and private actors to play new entrepreneurial roles. The Gaziantep Metropolitan Municipality has been a pioneer in this process, promoting policies that promote cultural tourism as an engine of economic growth. Under its leadership, hundreds of historic buildings have been restored, nine new museums and heritage sites opened, and museum visitors increased tenfold. These positive results make Gaziantep an interesting case of successful decentralisation in heritage management. Despite these successes, however, the disconnection between rhetoric and results, and the fragmentation and ambiguity of responsibilities emerging from the decentralisation process raises serious questions about its sustainability and replicability.  相似文献

There has been legislation in place since the 1970s in Canada's largest province, Ontario, that encourages the identification of significant heritage buildings and is supposed to provide them with at least a degree of protection. Both heritage recognition and most other land use decisions, however, are exercised at the local government level. W'hile conservation of heritage structures has been successful in some places, an alarming number of significant historic buildings in the province continue to be lost. Relying on dozens of volunteers, this study examined thousands of buildings in over twenty Ontario communities and sought to establish how many heritage buildings had been demolished and to determine why these losses were occurring. It was discovered that in the municipalities surveyed over 400 historically recognised buildings had been lost in the last sixteen years. Recommendations for how to deal with this problem are included in the study.  相似文献

This article synthesizes recent advances in the study of astronomy and worldview in architectural and urban planning in Mesoamerica. Throughout most of this cultural area, the practice of orienting civic and ceremonial buildings followed similar principles, although regional and time-dependent variations are present. Analysis of alignment data has revealed the existence of distinct and widespread orientation groups; most refer to sunrises and sunsets on particular dates, although two groups can be related to lunar and Venus extremes. Astronomically relevant directions frequently dominate considerable parts of urban layouts. The orientation and the location of important buildings often were conditioned by astronomical criteria and beliefs about specific landscape features; particularly notable are structures that were aligned to prominent mountaintops on the local horizon. Based on a variety of contextual data, I interpret the uses and significance of orientations in terms of agricultural concerns, cosmological concepts, and political ideology. I outline the evolution of orientation practices, drawing attention to pan-Mesoamerican trends, regional patterns, and diffusion processes.  相似文献

ABSTRACT

The seismic vulnerability assessment of historical UnReinforced Masonry (URM) buildings is a very complex task since it is strongly related to a great variety both of geometrical layouts and of masonry mechanical characteristics. In this article, some results of a Catania University research project, denomined “FIR 2014”, focused on the seismic vulnerability estimation of historical buildings, built in Catania after the 1963 earthquake, are presented. First, a detailed typological analysis of the considered urban fabric, characterized by typical residential masonry buildings, has been performed. Such analysis allowed recognizing an elementary structural modulus, which has been studied according to different geometrical layouts representative of isolated or aggregate buildings. The results of nonlinear static analyses, performed by applying an innovative macro-element approach, allowed for the assessment the seismic vulnerability of typical URM buildings coherently to the Italian seismic code. The adopted macro-element strategy for the seismic assessment of aggregate masonry buildings, although related to a specific historical center, may be applied to similar urban fabrics and can also be used for the calibration and validation of fast seismic assessment strategies, particularly useful for the evaluation of the seismic risk at urban scale.  相似文献

Micro-Raman spectroscopy has been applied to painted stucco samples from three buildings at the Maya site of Copan, Honduras. The buildings, Clavel (AD 450–550), Ani (AD550–650) and Structure 10L-22 (AD730,) date from three phases of the Classic Period (AD400–820) acropolis construction. The red pigment has been identified as haematite and the stucco as a mixture of calcite particles dispersed throughout a calcite based lime wash stucco. The physical structure of the stucco changed through time, indicating a refining of production techniques over this period. By combining Micro-Raman spectroscopy with other micro-ATR infrared spectroscopy and environmental scanning electron microscopy a detailed investigation of the materials and production techniques used to decorate these buildings has been made. Differences in the mineralogy of the red pigment used on each building indicate a different geological pigment source for each period.  相似文献

In this article, one of the procedures proposed in literature for the design of viscous dampers to be inserted in existing buildings is examined and extended to 3D eccentric buildings. The proposed procedure has been verified through a case study characterized by a six-story RC building. Both plan-symmetric and plan-asymmetric configurations have been considered for comparisons. The effect of considering the plan-asymmetry in the design has been studied. Moreover, also the importance of considering the higher modes has been investigated. The effectiveness of the design procedure has been then evaluated through the comparison with nonlinear dynamic analyses.  相似文献

ABSTRACT

The protection of cultural heritage against earthquake induced actions is one of the main challenges the earthquake engineering science and practice are facing. This article presents a seismic assessment study on one of the most ancient colonial buildings present in Peru, the Cathedral of Lima, focusing on its towers. A historical review highlighted how these structures, together with the whole Cathedral, suffered intense damage and partial collapse during previous earthquakes. In order to identify the structure main deficiencies, both linear kinematic analyses and nonlinear static analyses have been performed. Different nonlinear finite element models have been created to evaluate the influence of the adjacent walls. Different load distributions have been compared to evaluate how simplified patterns could provide results close to load distributions taken from a modal analysis of the complex. A simple retrofit strategy, consisting on the introduction of steel ties, has also been studied as a reference. Results show good correlation between kinematic and pushover analyses. The construction, when compared to the requirements of the national code for new buildings, results significantly vulnerable, pointing out the need to accept some structural damage even after seismic retrofit.  相似文献

Until recently the ‘heritage industry’ in England overlooked buildings of minority faith traditions. Little has been written about this ‘under-represented’ heritage. Drawing on data from the first national survey of Buddhist buildings in England, we examine the ways in which Buddhist heritage is beginning to be incorporated into the state-funded ‘heritage industry’ as well as how Buddhist communities in England construct heritage through these buildings. First, we draw upon spatial theory in the study of religion to examine three dimensions of minority faith buildings in England and what this tells us about the communities involved: ‘location’ (i.e. the geographical location of the buildings); ‘space’ (i.e. what the buildings are used for and their relationship to local, national and transnational scales); and ‘place’ (i.e. what types of buildings are selected by different communities and why). We then turn to theories of memory that have become popular within the study of religion as well as heritage studies. Religion understood as ‘a chain of memory’ plays an important role in heritage construction via faith buildings, and an analysis of faith buildings, their spatial dimensions and role in ‘memorywork’, helps us think through the dynamics of modern religious belief in a multicultural and post-Christian setting.  相似文献

Archaeological excavations in advance of quarrying at Cheviot Quarry, Northumb. have produced important evidence for Neolithic, Late Bronze Age and Dark Age settlements. Neolithic pit features containing domestic midden material including broken pottery, lithics and cereal grains from two distinct parts of the quarry have provided evidence for what is interpreted as settlement and subsistence activity from the Early and Later Neolithic periods. Together with the Neolithic remains from the nearby sites at Thirlings and those recently excavated at Lanton Quarry, it provides evidence for significant, and perhaps intensive, settlement on the sand and gravel terraces of the Milfield Plain throughout the Neolithic. Indeed, these sites provide the precursors to the better known ceremonial and henge complex located nearby which probably dates to the Beaker period. Radiocarbon determinations associated with the full sequence of Neolithic pottery have been obtained from Cheviot Quarry and analysis of the residues adhering to the ceramics has provided some of the earliest evidence for dairy farming in the region, as well as information relating to other dietary and subsistence practices. Two substantial roundhouses with porches, internal hearths and pits containing domestic refuse, provide the first evidence for Late Bronze Age lowland settlement in the region. The botanical macrofossil and faunal evidence, together with the pottery residues, show clear evidence for arable and pastoral activity in a small, unenclosed farming settlement. A detailed programme of radiocarbon dating and the application of Bayesian modelling has shown that these two buildings are contemporary and date to the tenth century cal. BC. In addition to this prehistoric archaeology, three Dark Age, rectangular, post-built buildings were also discovered on the site and have been radiocarbon dated to the fifth or early sixth century cal. AD. These substantial, although heavily truncated, structures are thought to represent the homesteads of a small farming community, although the lack of material culture makes understanding their use and cultural attribution problematic. Because of their early date these buildings could have belonged to either post-Roman British inhabitants or perhaps early Anglo-Saxon mercenaries or settlers. A reconstruction of one of these buildings has been built close to the site at the nearby Maelmin Heritage Trail where it can be visited by the public.  相似文献

A prominent urban geographer presents a sweeping review essay on monumentality in the urban design of world cities. After outlining a number of the large, grand urban plans and projects of the past and present, he focuses on the four components of monumental urban design: comprehensive conceptions of legible urban form; iconic buildings; integrated urban transportation hubs; and planned downtown and midtown redevelopment projects. Concentrating on the trends prevailing at present and over the near future, the author notes factors that may exert a special impact on emerging world cities in Russia and China and argues for the importance of process in the geography of monumentality.
