    A Strategy for Disaster Risk Management Regarding Deliberate Destruction of Historic Urban Sites: Antakya, Turkiye
    (01. Izmir Institute of Technology, 2023) Mamaklı, Fatma Sezgi; Turan, Mine
    The protection process of cultural heritage before, during, and after a possible deliberate destruction is not well defined in the Turkish legal system. This study aims to present a deliberate destruction risk management plan (DRMP) for historic urban sites considering all phases of deliberate destruction risk with an emphasis on before destruction phase. Suggesting the content of the future work for during and after destruction phases and simulating the proposed before destruction measures for the historic urban site around Uzun Çarşı Street and Habib-i Neccar Mosque in Antakya are among the objectives. DRMP was proposed for historic urban sites by defining the techniques of risk management: assessment, reduction, mapping, and implementation. Risk factors for traditional streets and heritage buildings in a historic urban site were determined with reference to numerical and categorical data of physical properties, heritage values, and managerial characteristics. Risk parameters were determined as hazard and exposure, vulnerability, and coping capacity which were calculated with risk factors. Risk assessment and risk reduction implementation and mapping were prepared as a guideline by the collaboration of information coming from the site survey and literature review. The preparedness of historic urban sites against deliberate destructions was increased by the risk reduction strategies of DRMP. Results obtained by implementation of risk assessment strategies of DRMP to the case study area showed that the southeast of the case study area has high risk level. The implementation of risk reduction strategies created a dramatic decrease of risk level from high to low for most of the traditional streets and heritage buildings.

    Integration of Archaeological Sites With Urban Life in the Metropolitan City Centres: the Case of Agora of Smyrna/İzmir
    (Izmir Institute of Technology, 2022) Çalışkan, Merve; Turan, Mine
    This thesis aims to identify the parameters for the integration of archaeological sites in metropolitan city centres with urban life. The Agora of Smyrna was chosen as the case. The method proposed has five phases: Literature review, archival research, physical and social surveys; the Delphi study; and statistic evaluation. The Delphi study was used to define integration criteria and their weights. The correlation and regression analysis were carried out to define the content and level of integration of the citizens with the site. Sequential according of the criteria set with information coming from different sources such as literature, social surveys and Delphi study distinguishes this study from the previous work. Identification of weights of criteria via the structured communication technique made it possible to attribute significance to the outstanding aspects of integration. The indicators of each criterion were clarified and criteria were classified to define integration concepts. So, an integration framework with a hierarchical structure was developed. The integration concepts “Possesing physical access”, “Possessing social usage”, “Being a well-presented site”, “Being a well-managed site”, and the “Presence of public concern for the conservation of the site” were identified as significant for integration. New integration concepts such as “Providing benefits to its vicinity”, “Being surrounded by a qualified urban area”, and “Awareness and positive perceptions of the site’s vicinity” were identified. “Presence of public concern for the conservation of the site” is the most important integration concept whereas “Providing benefits to its vicinity” is the least important integration concept for the case of Agora. The integration level of Agora with urban life and the integration of the citizens with the site was determined as moderate.

    Structural Vulnerability of Ancient Dry Masonry Towers Under Lateral Loading
    (Izmir Institute of Technology, 2019) Gençer, Funda; Turan, Mine
    In the Antiquity, masters constructed dry masonry towers that were resistant to earthquake potential of their sites. Determination of the authentic characteristics, that play role on structural behavior, developed in antiquity should be the first step of conservation planning. This study aims to identify the structural behavior of dry masonry towers under lateral loading in relation with their characteristics so that decision making phase regarding their restoration projects can be supported. Dry masonry towers in ancient Caria, Pamphylia and Cilicia, which have different ground accelerations, are examined. Methodology of the study consists of documentation of six case studies with traditional methods, design of hypothetical towers, impact analysis of towers with quasi-static tilt technique, examination of results in terms of collapse angle and failure mechanisms, discussion with the help of the statistical approach, and proposal of a framework for vulnerability rankings and possible failure mechanisms. As a result, parameters effecting structural resistance in the order of high impact to low are staggering ratio, stone depth, ratio between block length and height, proportional relationship between height and length, opening area, number and position and even distribution of header stones. These parameters have impact on each other; so, sustaining of the qualities regarding all of them should be undertaken in their conservation. Furthermore, it is seen that there was awareness of the necessity for usage of different anti-seismic parameters in different earthquake regions. However, appropriate combination of parameters with each other were not always undertaken possibly because of limitations of local materials, budget, time or masters.

    Assessment of the Interventions Regarding Some Historical Mosques in Manisa Within the Frame of Conservation Values
    (Izmir Institute of Technology, 2018) Koşun, Suna; Turan, Mine
    In spite of the fact that General Directorate of Pious Foundations has will to provide budget for the restoration of waqf origined monuments, there are still contradictions in the related restoration applications. There is an increase in the number of restorations and decrease in the ratio between technical staff and project number. The aim of this study is to understand effects of changes on cultural asset values of waqf origined monuments which have sustained their authentic functions, evaluate the change in the values period by period, assess the current interventions, present restoration history, and propose principles for future interventions that will sustain cultural asset value. Historical mosques in Manisa and dated to different ages are selected as case studies: Haki Baba Mosque (1371), Göktaşlı Mosque (1630-31), Kabasakal Mosque (≤1841), Pazaryeri Mosque (1874) and Çarşı Mosque (1875). Mixed methods combining qualitative and quantitative techniques were used. In conclusion, picturesqueness value, spiritual value, virginity value, rarity value and age value of the monuments and their period by period changes are stated. Scale of intervention, delicacy of the monument and appropriateness of interventions in relation with principles such as reversibility, transmission of data, physical sustainability, and qualified design and workmanship were defined as the parameters that have direct impact on the sustaining of values. In addition, history of restoration of the studied mosques and principles for future interventions regarding similar structures are put forward.

    Development of a Database for the Restitution Phases of Kurşunlu Khan in Manisa
    (İzmir Institute of Technology, 2016) Saygı, Gamze; Turan, Mine
    Historic buildings are not constant assets, they are representations of mankind and cultural systems throughout the time. In such a context, it is important to enlighten the process of building’s evolution by means of restitution(s), i.e., descriptions of different (re)compositions of buildings for different historical states. Hence, restitutions are used as works of synthesis in architectural conservation, and it is a mandatory part for it. On the other hand, representation of information beyond geometric, spatial and physical characteristics of a historic building carries a crucial importance for a holistic understanding of changes in those restitutions. This requirement is a multi-fold manner consisting of representation, archival, assessment and management aspects. Regarding those aspects, databases offer promising possibilities. Nevertheless, covering the requirement of the restitution state(s) is yet quite challenging if also visualization in digital three dimensional (3D) platform is considered, which is the most desirable way since it offers users an unrestricted and holistic visualization. Accordingly, this thesis proposes a methodology for the development of a database for the restitution states of a historical monument covering not only geometric and spatial aspects, but also historical resources. The thesis has a motivation to make sharing of restitution information, and decreasing future investigation effort in order to reach information of different historic periods. In this frame, Kurşunlu Khan in Manisa, Turkey, a typical building type of Ottoman architecture (şehiriçi hanı), dating back to 15th century, is selected for testing the methodology. The principles for collection and analysis of the data regarding the case study, structuring the database, and its visualization and access possibilities are defined. The thesis concludes that database may be an efficient tool supporting both the planning of a restoration project, and archiving of comprehensive results for later interventions and research. The resulting visualization options through the database and semantically enriched 3D model effort to make an easier understanding of historic changes specific to the monument. The database is open for improvement with conservation-aimed information.
