It has been pointed out that the static lateral response procedure for base isolated structures presented in IBC somewhat overestimates the seismic story force [Lashkari and Kircher, 1993; Constantinou et al., 1993]. In this article IBC equivalent static method for base shear distribution of seismic isolated structures is evaluated. For this purpose one-story to six-story building models are designed according to equivalent lateral response procedure for different elastomeric isolation systems. The results of equivalent lateral response procedure in parameters such as base shear and vertical distribution of base shear are compared with results obtained from dynamic nonlinear analysis and the efficiency and limitations of its application are investigated. In general, the results of equivalent lateral response procedure in base shears are acceptable within the scope of this procedure, but the proposed triangular distribution of base shear is somewhat conservative. So a new formulation for vertical distribution of base shear is proposed which results in a more realistic distribution of shear over the height of isolated buildings. The accuracy of the new formulation is examined by comparing the resulting responses obtained from this study with those calculated by nonlinear time history analysis. 相似文献

Haig, D.W., October 2017. Permian (Kungurian) Foraminifera from Western Australia described by Walter Parr in 1942: reassessment and additions. Alcheringa 42, 37–66. ISSN 0311-5518.Exceptionally well-preserved siliceous agglutinated Foraminifera originally recorded by Walter Parr in 1942 are redescribed and illustrated by rendered multifocal reflected-light images. Significant new observations are made on wall texture and apertural morphology. The specimens are from the Quinnanie Shale and lower Wandagee Formation in the Merlinleigh Sub-basin of the Southern Carnarvon Basin, a marginal rift that splayed from the East Gondwana interior rift. During the Early Permian, a restricted shallow sea inundated the rift. The formations are part of sequence III of the Byro Group and belong within the Kungurian Stage (Cisuralian, Lower Permian). Of the 14 agglutinated species described by Parr, six are retained under their original names, viz., Hyperammina coleyi Parr, 1942, H. rudis Parr, 1942, Ammodiscus nitidus Parr, 1942, A. wandageeensis Parr, 1942, Tolypammina undulata Parr, 1942 and Reophax tricameratus Parr, 1942; one is transferred to a different species, viz., Thurammina texana Cushman &; Waters, 1928a; six are placed with other genera, viz., Thuramminoides pusilla (Parr, 1942), Teichertina teicherti (Parr, 1942), Sansabaina acicula (Parr, 1942), Tolypammina? adhaerens (Parr, 1942), Kunklerina subasper (Parr, 1942), Trochamminopsis subobtusa (Parr, 1942); and a species of Ammobaculites Cushman, 1910 identified by Parr is now left in open nomenclature. From Parr's material, eight additional species are described: two new species, viz., Hyperammina parri sp. nov. and Gaudryinopsis raggatti sp. nov.; rare representatives of Aaptotoichus quinnaniensis Haig, 2003; and very rare species of Lagenammina Rhumbler, 1911, Giraliarella Crespin, 1958, Glomospira Rzehak, 1885, Hormosinella Shchedrina, 1969, and Reophax Denys de Montfort, 1808, all of which are left in open nomenclature. Hyperammina rudis is the type species of Hyperamminita Crespin, 1958, a genus now considered a junior subjective synonym of Hyperammina Brady, 1878. Thuramminoides pusilla is considered a senior subjective synonym of T. sphaeroidalis Plummer, 1945, the type species of Thuramminoides Plummer, 1945. Imagery is presented confirming that the simple cylindrical canals through the wall of Teichertia teicherti differ from the branching canals in Crithionina rotundata Cushman, 1910, type species of Oryctoderma Loeblich &; Tappan, 1961. The collection contains some of the earliest representatives of the revised family Verneuilinoididae Suleymanov, 1973, herein elevated from subfamily rank, and considered to include Pennsylvanian–Cisuralian representatives of Mooreinella Cushman &; Waters, 1928a, Aaptotoichus Loeblich &; Tappan, 1982, Digitina Crespin &; Parr, 1941, Gaudryinopsis Podobina, 1975, Caronia Brönnimann, Whittaker &; Zaninetti, 1992 (=Palustrella Brönnimann, Whittaker &; Zaninetti, 1992) and Verneuilinoides Loeblich &; Tappan, 1949.David W.

In the past, probabilistic seismic hazard analysis (PSHA) has been performed by researchers to assess the level of seismic hazard in Kuala Lumpur, Malaysia and its vicinity. However, the peak ground acceleration (PGA) values obtained are high due to unsuitable ground motion prediction equation (GMPE). This article is divided into two parts: development of a suitable GMPE and the PSHA for this region. Two main sources have been identified as the contributors to earthquake hazard in Peninsular Malaysia, namely the Sumatra strike-slip fault and Sumatra subduction zone. For the subduction zone, nine recorded large earthquake events are analyzed and regression analysis is performed to obtain a new GMPE for this region. In performing PSHA, the strike-slip fault is divided into 14 zones based on the individual fault segments, while the subduction is divided into 4 zones. Historical earthquakes of this region are collected, processed, and segregated according to the zones. PSHA has been conducted by modeling the source seismicity using Gutenberg-Richter and characteristic earthquake models. The developed GMPE has been used along with other attenuation models: Megawati and Pan [2010] and component attenuation model (CAM) by Balendra et al. [2002] for subduction; and Sadigh et al. [1997] and CAM for strike-slip fault. The peak ground accelerations in Kuala Lumpur for 10% and 2% probability of exceedances in 50 years are found to be 16.5 gal and 23.4 gal, respectively. From deaggregation analysis, the main contributor for the 10% probability of exceedance in 50 years is found to be a 7.5 Mw earthquake at 300 km, originating from the strike slip fault. Finally, the design response spectrum for Kuala Lumpur is developed for rock sites, which would be amplified further by local soil profile. 相似文献

This article addresses early work on partial recovery that followed small motor cortical lesions. Leyton and Sherrington (1917) studied the motor cortex in apes, hoping to learn more about the contralateral muscle representations. Then they placed small lesions within the precentral cortex, followed by a loss of the contralateral muscle twitches. The sudden loss remained for about one week, but recovery was observed and continued for weeks, up to a standstill. Sherrington and Graham Brown (1913) observed the same results in a serial, chronic experiment on a chimpanzee. The brain was sent to Monakow's Brain-Institute in Zurich for investigating the lesions and the degeneration pattern. Constantin von Monakow (1853–1930) had been a pioneer on recovery after acute lesions, coining the term “diaschisis.” During WWI, Graham Brown and Stewart (1916) studied a soldier in a British army hospital who suffered from a cerebral gunshot wound, localized in the sensorimotor cortex. Early and prolonged rehabilitation was successful. In 1950, Glees (1909–1999) and Cole (Oxford) placed a small motor-cortical lesion in macaque monkeys; for a few days, the monkeys had difficulties and were slow for the task. Daily training was resumed and recovery was accelerated by alimentary reward. Finally, Lashley (1890–1958) understood that handicapped patients “achieved their goal with variable means.” This demonstrated the value of active and prolonged rehabilitation, in addition to the (passive) recovery of function. 相似文献

This paper aims to show how young people in former East Germany respond to the globalising processes that are part of the transformation of their society from a state-socialist to a capitalist one. It focuses particularly on the differential ways in which young people perform their identities as global/local subjects through the uses that they make of urban space. While emphasising the agency of young people, the paper seeks to examine the dialectic between globalising forces that are largely beyond their control and the negotiation of these forces in everyday practices of identity-formation. Conceptually, the paper draws particularly on the work of Beck (2000), Beck and Gernsheim (2002) and Giddens (1994) in order to conceptualise the connections between globalisation and individualisation, as well as on feminist and recent geographical work on performativity (Butler, 1990, 1993; Rose, 1996; Gregson and Rose, 2000; Thrift, 1996; Dewsbury, 2000; Dewsbury and Naylor, 2002) in order to gain an embodied understanding of the ways in which individuals construct themselves as global/local subjects. 相似文献

As participatory methodologies gain popularity and are increasingly adapted to carry out research with ‘children’, I return to the methodological question: is doing research with children different from doing research with adults? (Punch, 2000). As a participatory researcher, I raise concerns around methods designed for ‘children’ that stamp a ‘how-to-research’ label upon a diverse group of individuals prior to entering the research space. Rather than continue the well-worn debate around the incompetent/competent/powerless child versus the competent all-powerful adult, I attempt a different approach that aims to dissolve this dichotomy. I draw on hybrid theories of identities (Benhabib, 1992; Butler, 1990; Adams, 2006), that recognise identities as multiple and fluid, and present social identities as unhelpful guides in designing participatory methods, principally the mythical notion of the competent all-powerful adult (Lee, 2001). I present the case that pre-labelling participants contradicts the bottom-up approach of participatory methodologies, particularly when Participation is understood as spatial practice (Kesby, 1999; Cornwall, 2000), and participants are invited into a research space, where identities are performed (Thrift, 2000) and are, therefore, something we ‘do’ not ‘have’ (Butler, 1990). 相似文献

Despite the vast influence of “Chinese culture” on Korea, the Chos[obreve]n dynasty (1392–1910) was a distinct cultural sphere governed by its own internal logic that centred on the aristocracy. Over the past twenty years, the importance of this fact has received emphasis in detailed studies by Deuchler (1992), Palais (1996) and Duncan (2000). The recent works by Hwang, Park and Kim that are the subject of this essay constitute a triptych of studies that further illuminate theimplications of social status in Chos[obreve]n and show how South Korea's transformation over the past five decades represents a radical deviation from the defining characteristics of its Confucian past. 相似文献

Lead-rubber isolators represent a valid and economic solution for the seismic isolation of bridge structures and modern manufacturing techniques make available large devices. Velocity effects on small to medium-scale isolators have been discussed by several authors (e.g., Clark et al., 1997; Thompson et al., 2000) as well as included in reports of experimental programs (e.g., CERF, 1999). Only recently, however, the behavior of large devices was validated under full-scale displacements, loads, and velocities. In this article, results obtained from an experimental investigation on the effects of axial load and strain rate on the performance of a full-scale lead-core elastomeric bearing for bridge applications, are reported. The bearing response was analyzed with particular attention to the variation of critical performance characteristics in order to produce a set of information that could be implemented in a physically motivated numerical model. The results, in line with additional tests performed on similar full-scale bearings at the Caltrans SRMD Testing Facility at the University of California San Diego, indicate a moderate effect of the applied vertical load but a significant effect of the strain rate and cycling on all the significant response parameters. This information should be taken into account by designers, particularly when high component of velocities are associated with the expected seismic motion. A simplified numerical model is proposed for the assessment of lead-rubber bearing performance. 相似文献

Regional syntheses based on data recovered mostly from outside of the Northern Range have characterized the mountainous region in northern Trinidad as a boundary between two distinct interaction spheres during the Early Ceramic Age (ca. AD 350–650/800) (Boomert 2000). Changes occurring on Trinidad, other islands of the southern Lesser Antilles, and the South American mainland resulted in the disintegration of these earlier style zones during the final centuries of the Early Ceramic (Boomert 2000, 2010). This period of Late Ceramic cultural realignment was characterized by climate change, the renegotiation of political and social networks, and demographic transformations. We consider newly recovered ceramic evidence from the central Northern Range in order to evaluate the characterization of the region as a boundary and the region's role in broader Caribbean trends. We examine participation in interaction spheres to provide a more nuanced understanding of regional dynamics as they were expressed locally. Ceramic data indicate that occupants of the central Northern Range interpreted regional styles using locally derived materials, thus simultaneously engaging regional traditions and constructing local patterns of resource exploitation. 相似文献

The concept of exchange has been on the anthropological agenda since Marcel Mauss published his book Essai sur le Don in 1925. The nature of gift-giving and exchange practices has since in different ways been developed and criticised (e.g. Bloch and Perry 1989; Bourdieu 1977; Derrida 1992; Dumont 1986; Levi-Strauss 1950; Sahlins 1974). However, exchanges are social practices that continue to puzzle and arouse curiosity within anthropology and related fields. The present article focuses on the vivid exchange practices that form part of social life in Sarijati village in Central Java.2 I will argue that exchanges here make up a social domain that articulates gender ideology and the reasoning of local morality. 相似文献

ABSTRACTThrough an analysis of the Petit Trianon, the historic house museum at the Château de Versailles associated with Marie Antoinette, the present article invites reflection over the topic of dissonant heritage (Tunbridge and Ashworth 1996) in connection with heritage commodification. The aim of this study is to heighten awareness of the difficulties which historic house legacies face in postmodern society through heritage analyses placed in the context of museology, art history and popular culture. This is achieved by building upon curatorial approaches and their reception by visitors, within an assessment of the 2008 restoration ethos of the Estate of Marie-Antoinette, and in parallel with a process of heritage commodification indirectly related to a twenty-first century Hollywood biopic of the last Queen of France - Sofia Coppola’s Marie Antoinette (2006). Competition surges between official and popular discourses of heritage (Groote and Haartsen 2008), all dealing, however, with the power of the same clichés engraved onto the French ‘collective memory’ (Halbwachs [1950]1980). This article highlights issues that arise when curatorial interpretation and visitor perceptions find themselves under the auspices of postmodern visual culture, thereby setting traps for heritage authenticity (Ashworth and Howard 1999). 相似文献

This paper aims to rethink “peasant consciousness” in colonial Egypt, through a study of the performance of folksongs by Upper Egyptian agricultural workers on the archaeological excavation sites of Karnak and Dendera at the turn of the twentieth century (1885–1914). Mainly based on a historical‐anthropological analysis of songs collected between 1900 and 1914 by the French archaeologists Maspéro and Legrain, this essay proposes a new understanding of subaltern consciousnesses as fragmented objects constructed through a dialectical relationship of power and resistance as performed by the various actors present on the scene. Drawing its inspiration from the work of contemporary ethnomusicologists (Finnegan 1977, 1992; Slyomovics 1987) and relying on the framework shaped by their use of oral‐formulaic and speech‐act theories, this study conceives of the performance, reception and collection of the songs as a crucial locus of encounter, interaction and negotiation between the local landless peasants employed as daily workers on the excavation sites, and the colonial administrators of the Antiquities Service during the key period of transition from corvée to contract labour. 相似文献

Calymene paronai Pellizzari, 1913 was described on the basis of an almost complete enrolled specimen from the Ordovician (probably the early Llanvirn Yangtzeella poloi Biozone) of southern Shaanxi, China. It represents one of the first Chinese trilobite species to have been established, but has been almost completely ignored by subsequent workers. This species is redescribed and reassigned to the Gondwanan inner shelf indicator calymenid Neseuretus, compared with other South Chinese taxa previously assigned to this genus, and interpreted as a senior synonym of N. concavus Lu, 1975. 相似文献

A RICHLY FURNISHED GRAVE from the migration period in Norway is our starting point for a discussion of the impact of dress in life and death. The Sande farm is situated on the southern tip of Norway on the Lista peninsula, an area renowned for its many rich finds from the migration period.4 A high-status grave from Sande in Vest-Agder was excavated in 2005 and was found to be lavishly equipped, not least in terms of jewellery items and dress fittings. Some remarkable textile remains were also preserved. The types of adornment and their position in the grave strongly suggest this was the burial of a woman, while the jewellery and textiles and their composition, style and appearance, all offer valuable information on the story of the individual and the dress code of the time. This article offers the first detailed exploration of this burial and its assemblage and an in-depth discussion of the surviving textile fragments and dress equipment as evidence of a form of dress and display that may have operated in life and death. 相似文献

Since the adoption of the Venice Charter in 1964, there have been many conservation guidelines in the form of charters, recommendations and resolutions that have been introduced and adopted by international organisations such as UNESCO and ICOMOS. This article focuses on the scope and definition of heritage as promulgated by the various charters across the globe. The term ‘historic monument’ used in the Venice Charter 1964 was reinterpreted by ICOMOS in 1965 as ‘monument’ and ‘site’; and by UNESCO in 1968 as ‘cultural property’ to include both movable and immovable. The different terminology between the UNESCO and ICOMOS was reconciled at the World Heritage Convention 1972. At national and regional levels the scope of heritage was broadened to include gardens, landscape and environment, and later reinterpreted and defined quite differently in Europe, Australia, New Zealand, Canada and China. Although the scope of heritage, in general, is now agreed internationally to include ‘tangible’ and ‘intangible’ as well as ‘environments’, the finer terminology of ‘heritage’ has not been streamlined or standardised, and thus no uniformity exists between countries. 相似文献
