Historic Barrel Vaults Undergoing Differential Settlements

ABSTRACT

A principal reason of damage in historic masonry vaults consists in relative displacements of the vaults’ abutments. Excluding the case of seismic-induced damage, cracks are often produced by differential settlements generated by the lateral wall instability or soil degradation (e.g., due to stress concentrations, non-uniform soil stratigraphy, flooding phenomena etc.). When dealing with historic vaults, the effects of long-term deformation processes cannot often be linked directly to causes, which may also be unknown. In this article, the effects of differential settlements on historic masonry barrel vaults are investigated. An efficient 3D contact-based model was developed to reproduce experiments on a scaled pointed barrel vault (representative of a typology of late-medieval barrel vaults in Scotland) under non-uniform differential settlement. First, the numerical model is used to simulate the experimental campaign, achieving good agreement in terms of crack pattern (longitudinal shear) and transverse-longitudinal deformation profiles. Then, further analyses are carried out to gain insight on the effects of several plausible uniform and non-uniform settlement patterns on representative historic barrel vaults. Various settlement configurations were analysed and complex failure patterns observed. This study could help analysts in understanding the nature of on-going deformation process in historic masonry vaults and engineers in the design of strengthening strategies.     

Multiproxy environmental archaeology of Neolithic settlements at Osłonki,Poland, 5500–4000 BC

Abstract

Archaeological research on Neolithic settlements (ca. 5500–4000 cal BC) at and near Os?onki, Poland, is complemented by palaeoenvironmental investigations in three basins with biogenic sediments adjacent to the archaeological sites. Research included sedimentology, palynology, malacology and cladoceran analysis. Complementary lines of evidence indicate that Linear Pottery pioneer farmers of the late 6th millennium BC caused minimal environmental impact, but intensive settlement and land use by the Brze?? Kujawski Group during the 5th millennium BC triggered pronounced human-induced effects on the local landscape. Of particular significance is the evidence for erosion and aeolian ablation of exposed soil in the vicinity of the Neolithic settlements, presumably reflecting widespread land clearance, agricultural activity and settlement construction.     

Crack Patterns Induced by Foundation Settlements: Integrated Analysis on a Renaissance Masonry Palace in Italy

This study presents some numerical results related to the analysis of the structural damage of a historic masonry building, Palazzo Gulinelli, in Ferrara, Italy. A detailed analysis of the inhomogeneities of the facade, historic documentation, and recent restoration interventions carried out in an adjacent building, suggest that the Palace underwent various modifications both on the structural configuration and on the borne loads. Such modifications might be the main cause of some differential settlements and of the consequent significant crack pattern on the load-bearing walls. Therefore, in the present paper the occurrence of a crack pattern on the facade is simulated by carrying out standard linear and non-linear finite element (FE) homogenized models; differential settlements are applied in order to reproduce the structural changes occurred over time. Previous experiences of the authors (for example, Acito and Milani in 2012 and Mallardo et al. in 2008), the current crack pattern of the building (of its facade in particular) and the monitoring data referring to some of them are the main references for the analysis carried out. The structural survey, the numerical results, and the data monitoring suggest two main conclusions: 1) a good correlation between numerical results and monitoring data is assessed, therefore the cracks can be reasonably related to past differential settlements; and 2) the cracks/damage that occurred as a consequence of differential foundation settlements reduce the ability of the facade to resist seismic actions.     

A Multidisciplinary Study on the Seismic Vulnerability of St. Agostino Church in Amatrice following the 2016 Seismic Sequence

ABSTRACT

The big earthquake of August 24, 2016 and subsequent major shocks severely damaged many historic villages in Central Italy and dramatically showed the intrinsic vulnerability of the diffused architectural heritage. The St. Agostino church is one of the collapsed historical buildings, being inside the epicentre village of Amatrice. During the long seismic earthquake swarm, progressively the church was damaged and monitored. This multidisciplinary study of the damage of the church includes correlations of all the data derived from three steps geomatics surveys (3D aerial and terrestrial models): the archival drawings and images documenting previous events distressing the building, the previous strengthening intervention, and finally the seismic site response analysis (from Amatrice’s accelerometric station). Through a back analysis carried out by a finite elements model, it was possible to understand the seismic vulnerability of this historical building, in relation to the previous interventions and damage events. The proposed methodology, based on the interdisciplinary data analysis, provides useful information for the next strengthening projects of damaged historical monument.     

The Iron Age landscape of Alcoi Valley,eastern Iberia: Agricultural intensification and sociopolitical dynamics

Abstract

New archaeological survey data are combined with previous evidence to examine the rural landscape during the Iberian Iron Age in the Valencia region of eastern Spain. One goal was to understand the settlement pattern and agricultural intensification through manuring. The second objective was to address the socioeconomic aspects of changes in the landscape. It is possible to trace the emergence of a hierarchical settlement pattern in the Iberian Iron Age in which large fortified settlements carried out the most important functions of control and exploitation of the territory, extending their authority over small rural villages and farmsteads. This pattern is associated with the complex socioeconomic structures and political organization of early Iberian states.     

Settlement networks and the organization of lithic tool production in the Late Prehistoric period (a.d. 1000–1780), Lower Nueces River Valley,South Texas

Abstract

Evidence from one of several Late Prehistoric settlement networks in the Lower Nueces River Valley in Texas demonstrates that base camps were surrounded by smaller-sized temporary camps. Local groups utilized nearby stone quarries, moved raw material to their settlements and reduced cores, preforms, and bifaces into tools for domestic use and portable toolkits. The Lower Nueces River Valley settlement organization and tool production during this period suggest restricted mobility, base camp sedentism, and abundant resource supply. This organizational structure promoted a complex foraging economy and perhaps the emergence of territorial clustering.     

The Transition from the Neolithic to the Copper Age: Excavations at Vésztö-Bikeri,Hungary, 2000–2002

Abstract

The transition from the Neolithic to the Copper Age on the Great Hungarian Plain (ca. 4500 B.C.) coincides with dramatic changes in house form, settlement layout, settlement distribution, and mortuary customs. These changes affected nearly every aspect of social organization—from the organization of households and villages to the distribution of cultural groups across the landscape. Our current understanding of the various changes that occurred during this important transition is hindered by a lack of systematically excavated settlement sites dating to the Early Copper Age on the Great Hungarian Plain.

The results of three years of excavation at an Early Copper Age settlement located in the Körös River Valley suggest that, in contrast to the Neolithic, craft activities on Early Copper Age sites are segregated in different parts of the settlements. This general pattern of increasing economic specialization occurs throughout SE Europe at the end of the Neolithic and is associated with a tendency towards increased integration of economic and social units in settlements during the Copper Age.     

The Concepts of imitatio and translatio: Perceptions of a Viking‐Age Past

The author presents the results of excavations at Mare Church, North Tr?ndelag. Medieval sources indicate that Mære was the religious centre for Inner Tr?ndelag in pre‐Christian times. It was also the place where the first church (shire church) in Sparbyggjafylke was erected. At Mære if anywhere, therefore, it should be possible to test archaeologically the theory about cult continuity from pagan to Christian times.

Under the present church, which dates from the end of the twelfth century, the remains of an early wooden church surrounded by a churchyard were found, together with vestiges of at least two buildings from pre‐Christian times. On the evidence of loose finds, the oldest of these can be dated to the Migration Period (c. A.D. 500). A series of gold plaquettes were found associated with the later of the two buildings. This find is interpreted by the author as indicating that the building may have been a pagan cult building.     

Small‐scale schooling and national development

In Greenland the conditions of the small settlement schools are very different from those of the large urban schools. And the opportunities (concerning further education and/or employment) for the young adults from the settlements are rather bad: Most of the young persons in settlements grow up to be unemployed and uneducated living on social welfare. Concerning the causes of the problems this paper calls attention to the importance of a multi‐factor theory operating on three levels: 1) Social factors in the settlement. 2) Factors in the school system. 3) Psychological factors.     

Report of the Portable Antiquities Scheme 2011

Abstract

Dutch East India Company (VOC) Fort Frederik Hendrik, the first European settlement on Mauritius, was established as a refreshment station for onward- and homeward-bound East Indiamen. The fort's archaeological remains offer a rich fund of information on a 17th-century stronghold and the population once in occupation. The material evidence reflects the fort's links with the Company's worldwide network of settlements, with both trade goods and people passing through. It also reflects cultural change and the settlers' endeavours to adapt to the local environment.     

Tools for Predicting Damage to Archaeological Sites Caused by One-Dimensional Loading

Tools are developed to predict damage to archaeological remains caused by the construction of line infrastructure on soft soil. They are based on numerical modelling and laboratory testing supported by X-ray microcomputed tomographic observations, and micromorphological analyses of thin sections. They have been validated for one-dimensional (1D) loading at two sites in the Netherlands where soil has been placed on top of organic layers rich in ecofacts and overlaying Pleistocene sands.

Numerical prediction of the deformation of soft layers underneath an embankment remains a challenge for geo-technical engineers. Errors on surface settlement prediction reach ±15% of the measured total settlement.

Laboratory observations show that vulnerable artefacts can get crushed when packed loosely in pure assemblies under 1D loading equivalent to less than 5 m of sand. Fragmentation is assimilated to loss of archaeological value as it compromises recovery during sieving. Embedment in a sandy or a very compressible organic matrix has a beneficial effect on the resistance of ecofacts. Embedded ecofacts can resist a load of more than 12 m of sand. Flattening and re-orientation of soft plant remains occur during 1D loading without microscopic damage of tissues.     

Medieval phases of settlement at Benabbio castle,Apennine mountains,Italy: evidence from Ground Penetrating Radar survey

The lack of written sources for many of the medieval castles in the northern Apennines (Italy) makes it difficult to completely establish the most ancient historical phases of these settlements. The church of San Michele belongs to an abandoned fortified settlement of the Castle of Benabbio, in the mountains surrounding Lucca. Thanks to an epigraph still visible on the façade, the church foundation is dated back to AD 1218. However, several archaeological findings at the settlement seem to suggest stages of encastlement that are older than the church foundation.     

Excavations of the 16th-century Protestant church and graveyard in Govče,north-east Slovenia

Summary

Archaeological excavations carried out in Gov?e ??near ?alec, Slovenia, have confirmed the location of the 16th-century Protestant church, destroyed by the Counter-Reformation Commission in 1600. These excavations have revealed the foundations of a polygonal nave, remains of the enclosure and part of a graveyard. This article focuses on the results of analysis of the burials, providing new information on 16th-century material culture. It provides historical background of the area and of the construction of the church, and presents the results of the excavation with emphasis on the graveyard, providing new information on Protestant burial customs employed in the late 16th century.     

Early Medieval Settlement in Southern Russia: Changing Directions

Abstract

THIS ARTICLE CONCERNS the evolution of approaches to the archaeology of early medieval settlements in southern Russia. Over the last 70 years, a large amount of data have been collected, especially from sites related to the Saltovo-Mayatsk culture on the Middle Don river. In this region, large-scale excavations since the 1930s have produced information about the types of settlements and dwellings, making it possible to suggest what the overall settlement pattern may have looked like. By way of contrast, the early medieval settlement archaeology in the North Caucasus is less developed even though its beginnings go back further. Sufficient data exist only about a few areas of the region, in particular Dagestan, the Taman’ peninsula, and the Kislovodsk basin. In the latter area, a new systematic approach to surveys of, and trial excavations on, early medieval settlements have led to the reconstruction of the complex settlement hierarchy of the 5th to 8th centuries AD involving central fortifications, enclosed villages and a system of watch-towers.     

The Timing of Angel Mounds Palisade Construction A Search for the Best Chronological Model

Abstract

Angel Mounds was a heavily fortified Mississippian settlement with several discrete palisades. Although the palisades were identified early on, the construction sequence has remained elusive because the construction episodes do not have stratigraphic relationships with one another. Recent work at the site reexamined old test excavations and collected new material for radiocarbon dating. AMS dating yielded a suite of new dates from palisade contexts. To refine the construction sequence, five Bayesian chronological models were constructed for palisade building. These models indicate that palisades were first built at Angel Mounds sometime between A.D. 1278 and A.D. 1410, which precedes or coincides with regional depopulation in the lower Ohio River valley. These results further indicate that palisade building at Angel Mounds may be a consequence of external competition and conflict caused by resource-induced stress resulting from deteriorating climatic conditions.     

Palaeoecology and Archaeology of the Village of Uukuniemi,Eastern Finland

Abstract

In the present article, pollen analytical results from Lake Kirkkolampi are presented and compared with results provided by archaeological material. Pollen analysis is connected with the archaeological research project at Papinniemi in Uukuniemi. Papinniemi is one of the numerous Greek Orthodox settlements that existed in Karelia in the fourteenth to seventeenth centuries. Archaeological evidence of settlement preceding this period is very scarce, and in this respect Uukuniemi represents a typical area in eastern Finland. There is no archaeological evidence of permanent settlement in Uukuniemi from the Early Metal Period (c. 1800 bc–ad 400), the Middle Iron Age (c. ad 400–800) or from the Late Iron Age (c. ad 800–1300). Pollen analysis demonstrated the onset of cultivation c. cal ad 300. Marked intensification of agricultural activities and cultivation in permanent fields took place around cal ad 800. A shift in land-use practises, including a declining use of fire, is visible at cal ad 1520–1600. The discrepancy between archaeological and palaeoecological records raises several questions, and the problems of Early Metal Period and Iron Age populations, as well as settlement continuity, are discussed.     

The identification of the medieval church of St Sabas in Jerusalem in the light of new documentary evidence

ABSTRACT

For over a century the church that the Greek monks of Dayr Mar Saba are known to have possessed inside the walls of Jerusalem in the twelfth century has usually been associated with a chapel surviving inside the Disy family house opposite the police barracks south of the Citadel, while the Zāwiyyat al-Shaykh Ya?qūb (Ya?qūbiyya), on the east side of Christ Church, has been identified as having originally been built in the twelfth century, possibly by Monophysites, as a church dedicated to St James the Persian, or the ‘Cut-up’ (Intercisus). New documentary research, however, now makes it appear more likely that Mujīr al-Dīn was correct in attributing the building of the Ya?qūbiyya to the Greeks and that it was also the church referred to by pilgrims in the twelfth century as that of St Sabas. This means that the identity of the church in Dār Disy, if indeed it was a church, remains to be determined.     

The meaning of sedentism and mobility in an archaeological and historic context

Sedentism is a commonly used concept in settlement pattern analysis. In a recent review of this concept Rafferty (1985) found “sedentary” to be related to both settlement permanence and site size. Both space and time are fundamental aspects of sedentism. While maintaining permanence as a central factor, this paper discusses further aspects of sedentism primarily in relation to the use and meaning of space. A case study based on archaeological and historical materials on Sami and Norwegian settlements in arctic Norway is used as an illustration. In arctic Norway prehistoric maritime settlements have often been interpreted as being either transhumant or sedentary. The prehistoric case of sedentism is then viewed in relation to the historically known differences in settlement permanence in space and time for Norwegian and Sami populations in the same area of arctic Norway. It is proposed that models of sedentism should not only be based on ecological, economic, and adaptational considerations but should also include the importance of the meaning of place in the relationship between human populations and landscape.     

Notes and News

Abstract

Most parts of Israel were excavated intensively, and most of the country was also covered by surveys. Our knowledge of settlement patterns and distribution during the various periods is very comprehensive — probably more so than in any other region in the world. Using data from the numerous excavations and from the detailed surveys, many studies have made use of various and sundry methods, in order to learn about the settlements and the population of the country, about changes in settlement patterns and distribution, and about periods of crises, decline, or growth.

Past studies, however, have ignored an entire array of findings that could have improved, refined, and even changed the familiar picture of the settlement history of ancient Israel. Thousands of salvage excavations ('rescue digs') were carried out over the years, and especially in the last decade, but these have not been dealt with systematically. These excavations provide comprehensive and reliable information, which is likely to change the picture of the history of settlement in some periods. While a comprehensive project of collecting and analysing the published data on these excavations is now in progress, the present article aims at drawing attention to this neglected source of information. We will demonstrate the advantages of this analysis as compared to other sources of information, and will show how this information, when combined with other sources of information, is changing our understanding of the settlement history of certain periods, including the transition from the Iron Age I–II and the formation of the Israelite monarchy, the nature of the Neo-Babylonian period, and the outcomes of the Jewish revolts against the Romans. The paper ends with a discussion of the advantages and limitations of the various sources of information, i.e., planned excavations, surveys, and salvage excavations.     

The Prehistoric Settlement Pattern of Nevis,West Indies

Abstract

This paper reports the results of an intensive settlement survey of Nevis, a volcanic island of 132 sq km in the Leeward Islands of the Lesser Antilles. Twenty-one sites were discovered from three major periods—the aceramic in the last millennium B.C., the Saladoid in the first 600 years A.C., and the Ostionoid period dating from 600 A.C. until European contact. The implications of the distribution of settlements and their artifact assemblages for the prehistory of the Leeward Islands are discussed.
