The Ottoman baths which have survived for hundreds of years are the historical structures still keeping their authentic architectural and technological properties. The study deals with the discovery of the knowledge on materials technology that contributes to the long-term durability of those structures. The authentic materials of an 18 th century Ottoman bath structure, Yeni Hamam (Sivrihisar, Turkey) were examined in this regard, in order to define the specifications for compatible repair materials which is essential for conservation studies. The physical and physicomechamical properties of the original stone, brick, mortar and plaster samples as well as their compositional and raw materials characteristics were examined. The results have shown that a gradual decrease in ultrasonic pulse velocity and modulus of elasticity values was observed through the wall section starting from stone-brick masonry followed by levelling mortar and finishing plaster layers. These values were also in correlation with gradual decrease in density and gradual increase in porosity of the same materials layers, respectively. In terms of raw materials characteristics, all mortars and plasters were found to be highly-pozzolanic materials. A gradual decrease in pozzolanic activity characteristics was also observed within the layers of wall masonry, starting from stone masonry mortars continuing with levelling mortars/plasters and finishing plasters. In addition, the same materials layers present high breathing capabilities and that is also very crucial for a highly-moisture loaded hamam structure. The presence of such healthier relationships exhibits a proper combination of layers contributing to good adherence between their interfaces and a durable structure. The knowledge achieved on compositional properties of authentic materials has vital importance for the preparation of compatible repair materials. The presence salt problem and growth of macro and micro plants on roof, ceiling and floor signal the severe dampness problems in the structure. Further analyses supported with non-destructive testing methods are needed for maintenance studies.

Repair Phases of Suleymaniye Complex in Damascus Şahin Güçhan, Neriman; Kuleli, Ayşe Esin (Middle East Technical University, Faculty of Architecture, 2018-6-28) Süleymaniye Complex in Damascus, built on the bank of Barada River as the last stop before the desert on the pilgrimage route extending from the Balkans to Mecca, is one of the works of Hassa Chief Architect Sinan, which was designed according to the basic principles of the Ottoman classical period architecture, and built between 1554 and 1559. Many research has been carried out on the historical and architectural features of the complex, which is composed of the mosque that is also known as the “Takiyah Sü...
Seismic Resistance Evaluation of Traditional Ottoman Timber-Frame Himis Houses: Frame Loadings and Material Tests Aktas, Yasemin Didem; Akyüz, Uğurhan; Türer, Ahmet; Erdil, Barış; Şahin Güçhan, Neriman (SAGE Publications, 2014-11-01) Traditional Ottoman timber-frame houses ("himis") form the major part of the cultural heritage structures in Turkey. There are many studies in the literature regarding the seismic performance of himis houses, which claim that these structures have an inherent seismically resistant property. However, these studies lack a quantitative engineering approach and are based on observations made after contemporary earthquakes. This study presents the results of the seismic resistance evaluation of traditional Ottom...
A comparative study on earthquake resistance of reinforced concrete and masonry residential buildings in small-scale cities of Turkey Er Akan, Aslı; Ünay, Ali İhsan; Department of Building Science in Architecture (2008) Today the vast majority of urban population in Turkey is living in multi-story apartment blocks constructed of reinforced concrete due to the fact that in the late 19th century concrete and steel took the place of traditional materials such as masonry. However, it cannot be denied that masonry is still a crucial material for load bearing walls, internal walls and cladding of buildings. In addition to this masonry construction system has many advantages. From the architectural point of view, it provides flex...
Assesing the Usage of Calcium and Magnesium Hydroxide Nanoparticles as Consolidant for Dolostones. Karahan Dağ, Fulya; Tavukçuoğlu, Ayşe (2018-12-01) Dolostone has been abundantly used in the construction of monuments during archaeological periods in Anatolia. Several of those monuments have some decay problems to be assessed and need conservation treatments to be developed. In the study, it was aimed to prepare a nanodispersive solution from the dolostone itself and follow its carbonation mineral phases in order to obtain a compatible consolidation treatment for dolostone. A mixture of calcium and magnesium hydroxide nanodispersive solution in ethyl alc...
Handling Sub-Soil Urban Archaeological Resources In Urban Planning, Issues In İzmir Historic City Centre Belge, Burak (Middle East Technical University, Faculty of Architecture, 2012-12-1) In Turkey, although most of the historic city centres have been continuously occupied since early ages, urban archaeological resources –cultural deposits underneath modern cities- could not be handled into planning process. It will be possible to strike the right balance provided that the archaeological resources are evaluated and considered in each stage of the planning and development process. At that point, urban archaeology is considered as an interdisciplinary field of study that evaluates the cultural...
