The Structural Conservation Problems of Traditional Houses in Eryeri, Mardin, Artuklu
(01. Izmir Institute of Technology, 2023) Ercan Gündüz, Yasemin; Turan, Mine; Aktaş, Engin
The aim of this study is to document the construction techniques, material usage, and structural failures of the traditional houses in a village of Mardin, Eryeri, in order to guide a conservation aimed development plan that will be prepared in the future and enhance the related rehabilitation implementations. Eight houses that have preserved their authenticity were selected. Field survey focusing on the structural elements such as foundations, walls, floors, and roofs was conducted with the conventional techniques of architectural restoration. Both failures and also alterations of the buildings were documented. The changes and alterations of the houses are documented. Visual analysis of the constructional qualities was made with Archicad23 tools. Comparison with the traditional houses in the vicinity was made with reference to data gathered via field survey, literature review and archive research. As a result, the traditional houses are integrated with the rocky terrain of the region and in masonry system. There is an intense use of local stone, Yellow Limestone. Vaults are common superstructure elements, but timber floor is also possible. The walls are stone masonry in all. The common structural problems are demolition of structural elements such as roofs. The causes of severe failures are neglect and natural aging. The reinforced concrete additions flanking to the authentic structures also cause failure. Within the scope of the conservation plan, it is important to prevent reinforced concrete annexes and to intervene the annexes that cause excessive loads urgently.

Preservation of Cultural Routes: Historic Center of Manisa
(Izmir Institute of Technology, 2019) Keke, Damla Gül Begüm; Turan, Mine; Akpınar, Figen
Cultural routes help perceiving the heritage elements in a historic urban site as a whole and transform their display into an enjoyable experience. Manisa historic center is chosen as the study area. The site has housed many civilizations throughout history and had been an important trade center on the historic silk road, but it has lost its integrity with the fire of 1922 followed by modern urbanization on the historic site. It is aimed to search the ways of presenting the isolated cultural and natural assets of the historic center through establishment of a cultural route. The way followed includes literature review, site survey, analysis, evaluation, proposal development and discussion. Features of examples and Manisa cultural route, such as route type, length, form and assets, discussed by comparison. As a result, a common vision for the cultural route of Manisa center with four different sub-themes is determined as “On the Trail of the Silk Road, the Cultural Network of Manisa.” The cultural route will revive the spirit of the caravan route, the experiences of the old travelers, and the traditional way of life. Linear formed, short length stages are suggested. Awareness of heritage protection can be improved by increasing the visibility of the assets along the route stages. It is expected that tourism activity in the region will increase. Proposing local-scale cultural routes in Manisa will pave the way for Manisa to participate in larger cultural route networks by conducting regional-scale route studies.
Structural Analyses and Assessment of Historical Çardak Caravanserai in Denizli
(Izmir Institute of Technology, 2019) Şahin, Esra; Aktaş, Engin; Turan, Mine
The assessment of historical masonry structures are significant in terms of transferring our cultural heritage to future generations. The conservation of these masonry structures is possible through investigating problems and their causes with tools such as structural modeling and analyses. In this study, the structural modeling and analyses of a historical masonry structure was aimed. Çardak caravanserai in Denizli was chosen as the case study since it has preserved its authenticity and integrity. In this scope, the software used for modeling and structural analyses was SAP2000 v20.2 commercial finite element software. For modeling, frame elements were used in the columns and shell elements were used in the other structural elements. Selfweight analysis, modal analysis and response spectrum analysis were conducted in terms of the assessment. The self-weight analysis was made under dead load. The analysis indicated the current state of the structure. In modal analysis, free vibration periods, mode shapes and mass participation ratios of the structure were determined. In response spectrum analysis, according to Turkish Siesmic Design Code 2018, mode integration method was used as linear calculation method. In this analysis, the khan was evaluated under the dead load and earthquake loads in the x and y directions. The structural elements that exceed the compressive, tensile and shear strength were identified as hot spots and recommendations on the further investigations on these critical points of the structure were presented.
Historical Development of Göztepe District in Izmir and Preservation Problems of Its Monuments
(Izmir Institute of Technology, 2019) Düzcan, İpek; Turan, Mine
Göztepe has transformed significantly with the loss of its suburban landscape and historic context of the late 19th century and early 20th century. The transformation of the historical context of the district started during the mid 20th century, when urbanization had caused the invasion of the district with high apartment buildings. The historical value of the site arises from its remaining assets. The study aims to present the historical development of Göztepe and its current preservation problems with an eye on its monuments: Arapyan Ispartalyan House, Susuz Dede Park, Notre Dame de Lourdes Church and Anadolu Apartment Building. The way followed is literature review, site survey, historical and archive research, comparative study, evaluation and discussion. The present historical monuments of Göztepe district had been built at the beginning of the 20th century, except the site of Susuz Dede Park, which originates in Hellenistic period (4th century BC). The types of the studied monuments vary according to their function as one educational, two religious or one residential type; and also, according to their quality as three cultural, and one mixed (cultural and natural). The recognition of the values of the district depends on the sustaining of these assets. It is concluded that the present state of Göztepe district is not successful as a representative of its historical characteristics; rather it indicates an insufficient long-term planning of urban development and conservation-oriented zoning. For the sustainable development of the district, a harmonious balance between the new and the old should be ensured. Preservation of the assets will contribute to presenting a much more valuable whole. A holistic approach is necessary in this manner for revealing the hidden values.
Structural Conservation of Cevher Paşa Bath in Kale, Denizli
(Izmir Institute of Technology, 2018) Durmuşlar, Feyza; Turan, Mine; Aktaş, Engin
The study has focused on structural conservation of a historical monument in an archeological site. Cevher Paşa Bath, which is located in Kale (ancient Tabae) archeological site in Denizli and dated to the 15th century, is selected as the case study. The aim of the study is to propose a framework for structural conservation of the ruins of Cevher Paşa Bath so that conservation work regarding similar masonry ruins in archeological sites belonging to Turkish period can be guided. First, the bath was documented by using 3D Laser Scanner. Then, historical and theoretical framework including development of baths, loads of masonry buildings and evaluation of interventions in similar cases was constituted. Characteristics of the case study was defined in terms of location, landform, history, site and mass characteristics, architectural features, structural characteristics, structural calculations and alteration analysis. Condition report of the bath was prepared in form of tables. To identify original state of the bath, restitution was carried out. Nevertheless, the restoration approach is not reintegration, but only consolidation and presentation in order to sustain integrity with the archaeological site whole. Therefore, to prevent further damages, emergency interventions such as temporary shoring are proposed. Structural calculations have revealed that strength of the walls corresponds to stresses and overturning moment. So, the restoration work includes only supporting of arch remains and the weakest corner of the bath, which was determined by calculations. Some walls of the ruin are weaker than other parts. These parts need further analysis by civil engineers, and if necessary, consolidation can be carried out. The monument management plan points out the necessity of collaboration of Kale Municipality, RT Ministry of Culture and Tourism, Aydın Regional Council for Conservation of Cultural Assets, Directorate of Excavations in General Directorate of Cultural Assets and Museums, Aydın Conservation Implementation and Inspection Office, Department of Architectural Restoration and Department of Civil Engineering of IZTECH and History of Art Department of Ege University, and monitoring of the changes the bath four times in every year.
Evaluation of Current Conservation Activities in Kuşadası Urban Site
(Izmir Institute of Technology, 2018) Yönetken, Elif Ece; Turan, Mine
This study was conducted to evaluate conservation activities regarding conservation council decisions in a middle sized, but touristic historic city on western coast of Turkey. The aim of the study is to evaluate the impact of the current conservation plan and conservation council decisions on the immovable cultural assets in listed urban site of Kuşadası. The methodology includes literature research, archive research in Conservation Council, Pious Foundations and Kuşadası Municipality, site survey comprehending base map correction and photographic documentation; visual analysis, historical research and comparative study, and evaluation of conservation activities with reference to concepts of authenticity and integrity. It is evaluated that there are conservation problems originated from inappropriate conservation implementations ignoring the concept of authenticity and integrity of immovable cultural assets. There is also terminologic confusion in some conservation council decisions. Majority of the conservation implementations have focused on single building scale. Unlicensed constructions stemming from insufficient control of the Municipality in the historic urban environment and lack of implementation of the conservation plan in terms of removal of inharmonious buildings and masses are significant in terms of their negative impact on integrity of the urban layout. Preparation of a management plan, revision of the conservation plan, which dates to 1994, and determination in their application are considered as indispensible for sustaining of authenticity and integrity.
Current Conservation State of Some Art Nouveau Houses and Apartment Buildings in Istanbul
(Izmir Institute of Technology, 2017) Türkarslan, Gizem; Turan, Mine
This study presents five examples of Istanbul Art Nouveau residential architecture in Sarıyer and Beyoğlu districts and their current conservation state. The aim is to evaluate two family yalıs in Sarıyer and three apartment buildings in Beyoğlu. First, Art Nouveau characteristics, its emergence in Europe and Istanbul were investigated. It was important to understand the changes in residential architecture in late Ottoman Empire and see the differences between its late and classical examples before starting to examine the buildings. After the historical research, analysis work of the five case studies had been carried out in site scale including the near-by environment and in single building scales. The way followed was survey with conventional techniques, mapping for visual analysis; literature and archive research in the related municipalities and the conservation councils. Then, each building was evaluated with the information coming from the analysis work and finally a general evaluation became possible. In conclusion, it is observed that Sarıyer and Beyoğlu examples have different conservation problems. Sarıyer examples have conserved both their façade and plan characteristics. They are currently used with the same purpose as their original function, restored and maintained. Their conservation problems are mostly caused by the interventions through the years to their near-by environment their original building material was renewed. In Beyoğlu examples, it can be said that façade of the buildings were preserved but interior organization was changed due to the function changes in Beyoğlu in general. Facades have become shells of the modern interiors.
Identification of Vezirağa Aqueduct in Izmir as a Historical Monument
(Izmir Institute of Technology, 2016) Mamaklı, Fatma Sezgi; Aktaş, Engin; Turan, Mine
During 17th century, the developing commercial activities in İzmir took the attentions of senior people from the government to the city. Köprülü Fazıl Ahmet Paşa realized the lack of water supply in İzmir and ordered to construct an aqueduct on Melez valley and fountains to the city center. The system was constructed in 1674 with an aqueduct named Vezirağa Aqueduct, ten old restored fountains and seventy-three new fountains in the city center. This study aims to identify historical, architectural and structural characteristics of Vezirağa Aqueduct so that its heritage values and conservations problems can be understood. The geographical and historical characteristics of Vezirağa Aqueduct are described by taking the effects of site and the socio-cultural situation of city into consideration. The architectural characteristics of the aqueduct are prepared by using the site survey datas to reveal the current condition and find out the original state. The original state of the structure explains its historical value and the importance during the construction period. The resistance assesment of the structure is defined by using equivalent static analysis and dynamic analysis by using finite element modeling and time-history analysis. Finally, the historical, architectural and structural characteristics of Vezirağa Aqueduct prove its historical, documentary and aesthetic values and the structural problems that can damage the aqueduct and affect its values.
