Historical structures have great importance since they form the basis of cultural identity of countries. Among these structures, those located in seismically active regions have been exposed to many earthquakes since they were built. Due to these seismic effects, historical structures are under constant risk of severe damage and collapse. Historical structures are mainly constructed as masonry structures prior to the development of more advanced and scientific construction methods and seismic resistance provisions. However, masonry construction is still important from the points of sustainability, durability, safety, appearance, and wide range of applications. There are thousands of historical structures located in Türkiye under considerable seismic hazard. Hence, a practical approach is necessary to receive a rapid and effective evaluation of the seismic safety. The approach selected in this study is the multi-criteria decision analysis methods. In this study, a preliminary seismic safety prioritization framework is proposed which does not require the application of extensive modeling and analysis approaches for assessment of historical structures in terms of seismic safety. Using this simplest framework, prioritization of the structures is aimed to take early precautions and to be more selective for future detailed studies. The framework presented herein evaluates the seismic safety of historical structures considering geological, seismological, structural and social parameters. In this thesis, a total of 250 different historical structures in Türkiye are selected and evaluated in terms of seismic safety. Almost all the cities of Türkiye are included in the dataset which provides an extensive study of the seismic safety of the historical structures in the country. In this dataset, various types of masonry structures such as churches, mosques, inns, and towers are included. As a case study, the proposed framework is applied to the selected historical structures.

An innovative methodology and structural analysis for relocation of historical masonry monuments : a case study in Hasankeyf Şener, İpek Neşe; Ünay, Ali İhsan; Department of Architecture (2004) Historical monuments are the most invaluable reflections of our architectural heritage and cultural identity, both of which have significant roles to create a strong link between the past and the present. They should be conserved in their own settings with their original characteristics or with as minimum changes as possible. However, natural or man-made hazards cause a serious risk for the survival of historical monuments. While some of them require to be strengthened only, some should be relocated to a ne...
An Inquiry into the accessibility of archaeological sites for people with physical disabilities / Çetiner, Meltem; Bilgin Altınöz, Ayşe Güliz; Erkılıç, Mualla; Conservation of Cultural Heritage in Department of Architecture (2018) The conservation of cultural heritage is globally regarded as a necessity, and directly emphasized in the international and national documents in a lawful manner. However, the accessibility to heritage places for people with disabilities has become today's common problem which requires a sensitive approach to overcome by means of some design related standardizations and new technologies. According to statistical data, there are 8.5 million people with disabilities that is nearly 13 percent of Turkey’s popul...
A Policy framework for sustainable tourism management in historic cities: the case of Amasya Sağıroğlu, Müzeyyen; Akkar Ercan, Zübeyde Müge; Department of City and Regional Planning (2016) The cultural heritage values in cities represent great opportunities for the tourism development. The conservation of the authentic character and identity of cultural heritage values and use of them without any degradation are important when considering the needs of present generation and the rights of future generations. From the global point of view, the tourism industry is seen as a fundamental component of economic development and continuously presents positive impact on the economy, environment and soc...
A Proposal for an administrative structure for cultural heritage management in Turkey Bozkurt, Ela; Serin, Ufuk; Department of Architecture (2017) It is generally accepted that cultural heritage, a valuable, limited and non-renewable resource, is today subject to many pressures, including tourism. Globalization, rapid urbanization and the consequent development pressures, the demands and pace of modern society have all created an overwhelming appetite for new housing, which compete for the shrinking areas of urban land available, all combine to constitute an environmental threat to cultural heritage. To respond adequately to these threats, it has beco...
Assessment and rehabilitation of the damaged historic Cenabi Ahmet Pasha Mosque Koseoglu, Gulsum Cagil; Canbay, Erdem (2015-11-01) Historic structures form a very important part of our cultural heritage and are supposed to be preserved properly. Therefore, full comprehension of the structural behavior of historic structures is of prior importance. In this study, a damaged single domed mosque of 16th century classical Ottoman Architecture has been investigated. Serious damage was recorded at various locations and structural elements including the dome and the structural masonry walls, as a result of which the structure was recently clos...
