Article Characteristic Architectural Elements of Traditional Barbaros Houses With a Single-Living Space and Their Relationship With Daily Life(Istanbul University Press, 2023) Saribekiroǧlu, Ş.; Kul, F.N.Barbaros is a rural settlement in Urla, Izmir, Turkey. This study aims to understand the architectural elements of Barbaros houses with a single-living space, their spatial organization, relation with daily life, and the local terminology for them. Moreover, it is aimed to reveal possible similarities and dissimilarities between architectural elements of other singleliving space rural houses in different settlements in close geography. The site survey data was collected in 2016, 2017, and 2020. Fourteen houses were examined, all of which still preserve their original spatial characteristics and architectural elements. The plans and architectural elements of each of the 14 buildings were documented in sketches and photographs. The architectural elements of each house and their characteristics, including form, material, and location in space, were analyzed. The Barbaros case was compared with other rural settlements in Çeşme, Karaburun and Urla. Oral interviews were conducted with 13 people to reveal the relationship between architectural elements and daily life. © 2023 The Author(s).Article Citation - Scopus: 3Characteristics of Byzantine-Period Lime Mortars and Plasters From the Anaia Church (kadikalesi)(Institute of Metals Technology, Ljubljana, 2022) Işık, Tuğçe; Uğurlu Sağın, ElifIn this study, Byzantine- period lime mortars and plasters used in the Anaia Church in Ku degrees adasy- Aydyn were examined in order to determine their characteristics and investigate the continuity of the lime mortar technology through centuries in the Anaia Church. The results will also contribute to future conservation studies at the site. Basic physical properties, raw-material compositions and hydraulic properties of lime mortars and plasters; mineralogical and chemical compositions, microstructural properties of binders, aggregates and limes; and pozzolanic activities of aggregates were determined using RILEM test methods, XRD, SEM-EDS and TGA. Mortar samples were comprised of natural aggregates whereas lime plasters were made of brick aggregates. Analyses revealed that plasters were slightly less dense and more porous than mortars due to the porous structure of the brick aggregates. All mortars and plasters were hydraulic due to the use of highly reactive pozzolanic aggregates. The basic physical properties, raw-material compositions, mineralogical and chemical compositions of mortars and plasters were found to be similar throughout the construction periods spread over different centuries. These similarities revealed the conscious knowledge of the lime mortar technology during the Byzantine period in Western Anatolia.Article Characterization of Yellow Patina on Stone Surfaces by Instrumental Analysis Including Libs(Taylor & Francis, 2022) Badur, Fulya; Aras, Nadir; Yalçın, Şerife; Böke, HasanYellow patina formed on the stone surfaces of historical buildings, monuments, and archaeological structures due to weathering is considered a value of the building in the conservation of cultural heritage studies. Although yellow patina layers can be easily distinguished on white marble surfaces, it is not possible to distinguish them on the yellow travertine surfaces with the naked eye. It should be taken into account in yellow travertines as well as marble surfaces before conservation treatments of the stone. In this study, mineralogical and chemical compositions and the thicknesses of yellow patina layers formed on yellow travertine and marble surfaces in Aizanoi, Aphrodisias, and Hierapolis archaeological sites in Turkey were analyzed in order to constitute a conservation approach in the archaeological sites. In this respect, XRD, FT-IR, SEM-EDX, and LIBS were used in the determination of compositions and thicknesses of yellow patina. Although LIBS analysis is a more convenient method to investigate patina layers on stone surfaces, this technique is not as well known as the others. Yellow patina layers contained calcium oxalate in the form of whewellite (CaC2O4.H2O). Their thicknesses were between 15 and 100 μm and should be protective against weathering on travertine and marble surfaces. Highlights LIBS analysis seems to be the most convenient micro-destructive method to estimate the thickness of the yellow patina layers on the marble and yellow travertine surfaces. The determination of the thickness of the yellow patina is critical to keep irreversible cleaning interventions, especially for the yellow travertines due to their similar colors. Yellow patina is mainly composed of calcium oxalate with clay minerals and organic compounds.Article Citation - WoS: 1Citation - Scopus: 1Plaster Characteristics of Byzantine Wall Paintings in Western Anatolia(Institute of Metals Technology, 2022) Şerifaki, Kerem; Böke, HasanIn this study, the execution technique and material characteristics of the plaster layers of Byzantine wall paintings from three archaeological sites (Anaia, Olympos and Aigai) from western Anatolia were examined for the purpose of their conservation. Throughout the study, mineralogical and chemical composition of the plaster layers were determined with a scanning electron microscope coupled with an X-ray energy dispersive system (SEM-EDS) and X-ray diffraction analyses (XRD). Reflected light microscopy (RLM) and SEM studies conducted on polished cross-sections of samples revealed the stratigraphy and microstructural properties of the plaster layers of the Anaia Church (4th–12th centuries), Baºpýnar Church (13th century) in Olympos and a Byzantine settling and the Chapel (13th century) in Aigai. Throughout the research, pure lime and aggregates in the plasters of Aigai, as well as magnesium-rich lime and straw in the plasters of Anaia and Baºpýnar were determined. The plasters from the Anaia and Baºpýnar Churches exhibit characteristics similar to the samples from the post-iconoclastic period due to a similar raw-material use. In the samples from Aigai, plastering techniques such as marmorino, intonachino and cocciopesto, indicating earlier periods, were observed. As a result of this study, it was concluded that the number and characteristics of the plaster layers from the paintings had been applied intentionally in accordance with the technique of the painting. Plaster characteristics of the wall paintings in western Anatolia from the Byzantine period were found to be similar to the ones in Ýstanbul, the Balkans, Crete and Cyprus. The results of this study will guide the conservation efforts of the wall paintings.Article Citation - WoS: 3Citation - Scopus: 3Microstructural Characteristics of Mortars Prepared by Hot Lime Mix(Union of Croatian Civil Engineers and Technicians, 2020) Şerifaki, Kerem; Uğurlu Sağın, Elif; Böke, HasanThe effect of lime characteristics and hot lime mix method on hydraulic, microstructural and mechanical properties of mortars is determined by producing mortars from quicklimes of two different marbles and two limestones. Results of SEM-EDS, XRD and TGA analyses reveal that the porous microstructure of mortars and spongy texture of calcite crystals are the indicators of the hot lime mix method. This study shows that characteristics of limestones used for the production of limes, as well as the preparation method, directly affect hydraulic, mechanical and microstructural properties of mortars.Article Historic Collective Shelter as Heritage: the Cases in Hurşidiye, Kurtuluş and Sakarya Neighborhoods in Konak, Izmir(İstanbul Üniversitesi, 2021) Hamamcıoğlu Turan, Mine; Akpınar, Figen; Toköz, Özge DenizHistorical collective shelters, yahuthanes or cortejos, are an alternative form of housing that were developed to provide secure sheltering of the groups who were disadvantaged in terms of economic, social, and cultural aspects in the Ottoman city. They have played a significant role in history as a building type that made possible cohabitation of groups, with moral and material problems, and struggling to maintain their integrity despite hardship. This study deals with a group of historical collective shelters in the traditional commercial center of Izmir dating mainly to the late 19th and early 20th centuries. The objective is to understand the historic evolution of collective shelters (yahuthane, cortejo) in Hursidiye, Kurtulus and Sakarya neighborhoods of Konak district in Izmir, to define their cultural values, to analyze their social and spatial development, to present their physical characteristics and evaluate their preservation problems. Eleven collective shelters were documented in the studied site, which is a portion of the traditional commercial center of Izmir (Kemeralti). The site comprehends the ruins of the Roman Agora and the remains of the public buildings dating to the pre-modernization period of the Ottoman Empire as well as the late Ottoman urban layout. As a method, the preliminary studies were reviewed, the land registers were surveyed, the present base map together with the historical maps were overlapped and the case studies were conducted using conventional techniques of architectural and urban conservation. The study has documented the interaction of Muslim and Jewish communities and how the collective living habits of these ethnic groups living in collective shelters differed from standard residential life at the end of the 19th and beginning of the 20th centuries in the traditional commercial center of Izmir. Though collective shelters in the historic center of Izmir have been studied in the literature, their specific location on the map was not available. This study has provided locations of the shelters and evaluated the architectural characteristics of their remains. The traces and remains of the historic collective shelters should be preserved as elements contributing to the integrity of the multi layered city.Article Citation - WoS: 1Citation - Scopus: 1Proposals for Monitoring Current Conservation Condition of Historical Masonry Buildings: Matrone Church and Çardak Han Cases;(Istanbul University Press, 2020) Durmuşlar,F.; Ipekci,E.; Turan,M.H.; Aktaş,E.The aim of this study is to transfer the international developments related to the process of diagnosis and monitoring of historical masonry structures to the national area. The method chosen is to test the recommendations made at the international level on national cases and to discuss the results obtained by comparing them. A review of preliminary studies, on-site observations, measured surveys, material characterizations, mapping and visual analysis have been carried out. An examination of structural characteristics and observed failures have also been detailed. Related risks have been evaluated with criteria developed by taking into consideration condition classes defined in the UNI EN 16096, titled Conservation of Cultural Property - Condition Survey and Report of Built Cultural Heritage. According to the defined risks and classes, priorities of interventions were determined. Two historical masonry buildings which possess characteristics of different periods and present different damage types were selected: Matrone Church in Ildiri, Çeşme, Izmir and Çardak Han in Çardak, Denizli. The condition reports of the selected buildings have been prepared. The critical points in the condition reporting of historical masonry buildings were determined: accurate comprehension of the authentic structural characteristics and related failures have priority in maintaining historical masonry structures. Identification of condition class and risk assessment of each historic masonry building should be made in accordance with a standard specific to the cases of our country, but in line with the European standards and current developments in the field of architectural restoration. Thus, it will be possible to evaluate the conservation state of our masonry assets in comparison with each other. The content and priority of interventions can be well planned with the participation of the necessary disciplines. © 2020 The authors.Article Citation - WoS: 5Citation - Scopus: 2The Masonry Techniques of a Historical Bridge in Hypokremnos (i̇çmeler)(Middle East Technical University, 2017) Uygun Gençer, Funda; Turan, MineThis study focuses on characteristics of a historical bridge in Içmeler, Urla, Izmir. Urla, a historical settlement on the west of Izmir, has been part of a commercial network between Karaburun, çesme and Anatolia throughout history. The aim is to understand the construction technique and material usage in Hypokremnos Bridge and identify a possible sequence of the original construction. The linear bridge was constructed by using masonry technique. It has three openings with various sizes and supported with rounded arches. The bridge wall is crowned with a road way making a crest at its center a inclined façade. This study is composed of four phases; documentation, analysis of construction technique and material usage, historical evaluation and restitution. In the first phase, by using Tgi3D Su Photoscan 2.13 and Trimble SketchUp 2013 software, three dimensional model was prepared. Visual analysis of construction technique and material usage was carried out and the mortar sample from the bridge was investigated in the conservation laboratory in the second phase. Three dimensional manual photogrammetric documentation of the historical bridge has provided the advantage of conceiving many constructional details. This condensed observation of constructional features supported with comparative study on historical bridges in Anatolia has revealed that the elements and composition of the studied bridge presents Roman characteristics, but the masonry techniques used recall those of Turkish period. The detailed data about structural system gathered from different locations of the bridge was used for the production of reconstitution of system detail. Reconstitution model of the bridge was produced by using reconstitution of system detail. To identify construction phases of the bridge, literature survey was carried out. According to structural elements and composition of the bridge, it is thought to be constructred in Roman Period, however, both the randomness in the composition of the rough cut lime stones used in the outer shells of the bridge wall, and lack of system in the form and color composition of the cut sand stones in the arches and the sea façade may be interpreted as an end result of a comprehensive repair on total reconstruction in the Turkish period.Conference Object Three Dimensional Modeling Via Photographs for Documentation of a Village Bath(Copernicus GmbH, 2013) Balta, H. B.; Turan, Mine; Ocali, O.The aim of this study is supporting the conceptual discussions of architectural restoration with three dimensional modeling of monuments based on photogrammetric survey. In this study, a 16th century village bath in Ulamiş, Seferihisar, and Izmir is modeled for documentation. Ulamiş is one of the historical villages within which Turkish population first settled in the region of Seferihisar - Urla. The methodology was tested on an antique monument; a bath with a cubical form. Within the limits of this study, only the exterior of the bath was modeled. The presentation scale for the bath was determined as 1 / 50, considering the necessities of designing structural interventions and architectural ones within the scope of a restoration project. The three dimensional model produced is a realistic document presenting the present situation of the ruin. Traditional plan, elevation and perspective drawings may be produced from the model, in addition to the realistic textured renderings and wireframe representations. The model developed in this study provides opportunity for presenting photorealistic details of historical morphologies in scale. Compared to conventional drawings, the renders based on the 3d models provide an opportunity for conceiving architectural details such as color, material and texture. From these documents, relatively more detailed restitution hypothesis can be developed and intervention decisions can be taken. Finally, the principles derived from the case study can be used for 3d documentation of historical structures with irregular surfaces.Article Citation - WoS: 2Citation - Scopus: 1Primary Schools of İzmir (1923-1950)(Middle East Technical University, 2012) Kul, Fatma NurşenThis study aims to identify primary school buildings constructed inIzmir between the years 1923 and 1950 and understand them withinthe national context and its reflection on the local. For this purpose, thenational primary education system and school construction policies wereresearched, and their local reflections were discussed through the specificcase of Izmir. The results of this research demonstrate that the national policies,instigating the extension of school buildings throughout the country, weresuccessfully implemented in Izmir, and contrary to numerous other cities,new school buildings were constructed homogenously not only in thecity and sub-province centers but also in the villages. This meant that, awide spectrum of schools differing in their scales and qualities, rangingfrom multi-spaced city and sub-province schools built in highly populatedareas to single-spaced village schools constructed in settlements of lowpopulation levels were built in Izmir. Detailed archival research, sitesurveys and literature reviews showed that 500 new primary schools werebuilt in 1923-1950, 99 of which provided information in more detail in theform of visual and written documents. Based on this data, it was possible toestablish the type of projects that were implemented in Izmir, the designingpersons or institutions, their design criteria and the school constructionprocesses
