Article Citation - WoS: 6Citation - Scopus: 10Construction Techniques of Domes in Some Ottoman Baths(Elsevier Ltd., 2013) Reyhan, Kader; İpekoğlu, Başak; Böke, HasanIn Ottoman bath architecture, the dome is the spherical structural component covering the square planned dressing hall, warm and hot spaces. In this study, the relationship between bond type, dome span, dome height, dome thickness, and the number of oculi of domes in some Ottoman baths located in Western Anatolia (Turkey) were investigated for the purpose of evaluating construction techniques and architectural characteristics. The studied domes were constructed with brick and lime mortar as binder. In the construction of domes, whole and half bricks with different dimensions were used. In all domes, the surfaces were covered with brick-lime plaster, a thin layer on the interior and a thick layer on the exterior. Terracotta pipes placed in the brick bond or the openings made through the brick bond constituted oculi for lighting. Depending on the brick bond, a linear relationship was determined between the span, height, and number of oculi, whereas a mathematical ratio between 1:10 and 1:12 was determined between the span and thickness of the domes. It has also been noted that as the dome span increases, so does the height, thickness at the springing level and the number of oculi. The domes examined with these properties should be seen as historical documents representing the construction technology of the 15th century. Therefore, these properties of domes must be preserved and special care needs to be taken as not to lose the original qualities of these domes during conservation works.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.Conference Object Structural Interventions for Conservation of the 15th Century Tahtakale Bath, Tire, Turkey(Trans Tech Publications, 2010) Mürtezaoğlu, Fulya; Kaplan, Çağlayan Deniz; İpekoğlu, BaşakTahtakale Bath, which is located in the town of Tire in the province of Izmir, Turkey, was constructed in the 15th.century and is one of the outstanding existing examples of Ottoman period baths. The building, which was designed as a double bath, was considerably damaged because of inaccurate interventions after losing its original function, lack of maintenance and natural circumstances. The parts which were reused have considerably lost their original characteristics. This study aims to introduce the construction technique of Tahtakale Bath, which was studied in the scope of a restoration project, and to present the studies on the determination of structural problems, structural strengthening decisions and implementations. Strengthening implementations were carried out in the bathing spaces of the men's section and felt workshop of the building depending on decisions of the restoration project. The original construction technique and materials of the walls, superstructure and architectural details of the building were consolidated by appropriate restoration decisions and implementation works. © (2010) Trans Tech Publications, Switzerland.Article Citation - WoS: 44Citation - Scopus: 44Ettringite Formation in Historic Bath Brick-Lime Plasters(Elsevier Ltd., 2003) Böke, Hasan; Akkurt, SedatTwo types of historic hydraulic brick-lime plasters from a selected Ottoman bath are examined to characterize their technology and the appropriateness of their use in bath. The first type of plaster is original and structurally sound, while the historic repair plaster is the second type and is found to have deteriorated despite being exposed to the same environment. This difference is investigated by comparing their raw material compositions and the pozzolanic activities of the brick powders used in the plasters. Although these results showed no significant differences, ettringite crystals are detected in the historic repair ones by XRD, FTIR, and SEM-EDS analysis. The repair plaster may have lost its integrity owing to the expansion generated by the growth of ettringite crystals in the plaster. In this study, the ettringite formation is discussed in relation to hydration reaction products of lime-brick plasters, possible sources of gypsum, and the climatic conditions of historic bath building.Conference Object Visualisation and Evaluation of Structural Characteristics and Problems of a Classical Ottoman Bath(WITPress, 2003) Çizer, Özlem; Turan, MineVisual documentation has been accepted as an important phase of architectural heritage conservation. Visualisation of structural characteristics and their problems, however, has gained importance in the last decade. In this study, structural characteristics are used to comprehend the characteristics of construction techniques and materials of building components. Structural failures such as loss of a structural element and cracks, and material deterioration such as loss of material and deposit are the main problems observed. Visualisation of structural characteristics and their related problems has been the basis of the methodology in this study. It is also considered important to underline the necessity of the design of a special visualisation technique peculiar to the characteristics of the monument under study.
