The traditional sacral wooden construction in Lithuania between XVIII and XIX century - Tradycyjne litewskie drewniane budownictwo sakralne z XVIII i…
2016
Litwa położona jest na gęsto zalesionych terenach Europy Północno-Wschodniej, stąd bogactwo budownictwa drewnianego w tym kraju. Wśród budynków drewnianych wyróżniają się obiekty sakralne, o dużej wartości historycznej, różnorodnej formie i rozmiarach, złożonych projektach i wieloetapowej realizacji. Najstarsze kościoły drewniane zaczęto budować na Litwie w XIII wieku. Obecnie na terenie kraju znajduje się ponad 600 drewnianych obiektów sakralnych, których aspekty konstrukcyjne i strukturalne nie zostały jeszcze szczegółowo zbadane. Główne cele przedstawionych badań to: – poznanie tradycji i rytuałów związanych z typami budynków oraz rozwiązań stylistycznych i architektonicznych wykorzystyw…
LA COSTRUZIONE IN LEGNO DEGLI EDIFICI DI CULTO LITUANI TRA XVIII E XIX SECOLO
La Lituania si affaccia a Est sul Mar Baltico ed è caratterizzata da un paesaggio di pianure boscose; in virtù delle riferite risorse di legname, annovera e custodisce un grande patrimonio di edifici in legno, dei quali gli edifici di culto sono quelli piu ricchi di valore storico e che presentano diversificate forme, nonché un ricco e complesso compendio di elementi materico-costruttivi della tradizione locale. Secondo il prof. Gennaro Tampone, questi edifici di culto costituiscono un prezioso documento sulla tecnologia e sulle caratteristiche strutturali del legno che testimonia un importante capitolo di storia della costruzione e delle tradizioni locali. La Lituania annovera attualmente …
The traditional sacral wooden construction in lithuania between XVIII and XIX century
2015
Lithuania is situated in a highly forested Northeastern Europe area and has a great variety of wooden buildings. Among the wooden structures we can enumerate the religious buildings, rich of historic values, presenting different forms and sizes and also a complex design and stratified construction phases. The oldest wooden churches began to built in Lithuania in the 13th century. Currently there are more than 500 existing wooden sacral structures, which not yet have detailed studies about their constructive and structural aspects. The main objectives of the research: • Knowledge of the rituals, related to the building types and stylistics and architectural solutions which were adapted to th…
Lithuanian wooden architecture : materials, ancient tools and constructive technologies for the safeguard of cultural heritage
2017
L'architettura in legno in europa costituisce uno dei più rappresentativi elementi del patrimonio da preservare. In questo studio si diescrivono le tipologie edilizie, i materiali, le tecniche costruttive e gli utensili dell'architettura lignea in Lituania, spesso ritrovati e ben dicumentati nei musei etnografici del Paese. Queste opere di carpenteria lignea devono essere ben studiate e d analizzare per garantirne la valorizzazione e la salvaguardia, utilizzando criteri di intervento compatibili e rispettosi dei caratteri originari dei manufatti. Traditional wooden buildings are a valuable part of European cultural and architectural heritage. The construction of wooden buildings presents a …
The traditional sacral wooden construction in Lithuania. An illustrated catalogue of building techniques for the safeguard and recovery of cultural h…
2015
La Lituania attualmente può annoverare un patrimonio di circa 600 edifici sacri in legno ancora esistenti, sui quali, ad oggi, non sono stati condotti studi approfonditi in merito agli aspetti storico/architettonici e tecnico/costruttivi. Questa tipologia di edifici costituisce un patrimonio della cultura architettonica locale da esplorare e conoscere, per garantirne la corretta conservazione e valorizzazione. La maggior parte di questi edifici di culto in legno versa in condizione di degrado poiché le comunità non sempre possiedono la dovuta attenzione e le competenze tecniche capaci per salvaguardare tale patrimonio. Le cause più frequenti di danno derivano da una inadeguata manutenzione,…
Lexical classes and constructions: an analysis of the constructional realization of entity-specific change-of-state English verbs
2013
This study analyzes a so far neglected part of the constructional behavior of Levin's (1993) entity-specific change-of-state verbs. More specifically, we discuss the integration of verbs from this lexical class into the intransitive-resultative construction. We base our analysis on the Lexical Constructional Model or LCM (Ruiz de Mendoza and Mairal 2008, 2011; Mairal and Ruiz de Mendoza 2009; Ruiz de Mendoza 2013). It will be shown that the internal and external constraints postulated by the LCM constitute useful explanatory and analytical tools for the fusion processes between these verbs and the intransitive-resultative construction. We also propose a classification of these verbs on the …
Flexural behavior of external beam-column reinforced concrete assemblages externally strengthened with steel cages
2016
In this paper, an experimental study referring to the flexural behavior of full-scale external beam-column joints externally strengthened with steel angles and strips and subjected to cyclic reversal loading is presented. One control specimen and five other specimens having the same characteristics as the control specimen but strengthened with steel angles and strips along beams and columns, and characterized by different configurations of strengthening in the critical regions, were tested. The control specimen was designed with a weak column and strong beam to reproduce the most common cases of old frame structures in the Mediterranean area, which were designed only for gravity loads and a…
Determining the Environmental Benefits of Ultra High Performance Concrete as a Bridge Construction Material
2017
Ultra High Performance Concrete (UHPC) is a material that is attracting attention in the construction industry due to the high mechanical strength and durability, leading to structures having low maintenance requirements. The production of UHPC, however, has generally higher environmental impact than normal strength concrete due to the increased demand of cement required in the concrete mix. What is still not sufficiently investigated, is if the longer lifetime, slimmer construction and lower maintenance requirements lead to a net environmental benefit compared to standard concrete bridge design. This study utilizes life cycle assessment (LCA) to determine the lifetime impacts of two compar…
Analysis of a Collapsed Long-Span Reinforced Concrete Roof in South Italy: Design Mistakes and Material Degradation
2020
In 2004, during ordinary maintenance work, consisting of waterproofing a building located in the south of Italy, the long-span (14.5 m) in situ RC roof partially collapsed. The building, constructed in 1950, was in service as a cinema until 1967 and then utilized as a school until 1985. Lastly, it was a hotel until 2000. In 2004, when the building was not in service and was undergoing maintenance work, it partially collapsed under dead load. After the collapse, which involved a large portion of the roof, several beams, and two columns, the Italian court nominated an official technical consultant to investigate the direct and related causes of the failure. After the main causes were identifi…
Excessive Deflection in Long-Span Timber Beams of a Historical Building in the South of Italy: Analysis and Retrofitting Design
2020
AbstractIn 2018, under service conditions, excessive deflections were observed in the long-span timber beams of the first floor of the former Sant’Elisabetta Monastery in Palermo (Italy). The build...
