    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.

    Structural Model Besed Root Cause Investigation of Damage in Urla Helvacılar Mosque and a Proposal for Strengthening
    (Izmir Institute of Technology, 2019) Narin Güzel, Ceren; Kul Özdemir, Fatma Nurşen; Aktaş, Engin
    The period when small independent beyliks (principalities) were founded in Anatolia in the 13th century is called the principalities period. The process of creating a new architectural style in Western Anatolia, as well as the works-built marks an important milestone in this period, which is defined as a transition period between the Seljuk architecture and the Ottoman architecture. The Aydın Dynasty, one of the important principalities of western Anatolia, had its capital at Birgi from 1308 to 1426. The dynasty is known for with its economic and political power and the important works it left behind. Helvacılar Mosque is one of the important works of the Aydın Dynasty, which was built in the 15th century and survives today. It is also an outstanding example to understand the single-domed mosque typology in western Anatolia. Helvacılar Mosque, located in the Kuşcular Neighborhood of the Urla District, is today derelict and abandoned. Heavy structural damage in the structure poses a grave risk for the structure to survive. This study compared and discovered the similarities and differences between Helvacılar Mosque and the similar-period structures situated in Urla and identified the architectural and structural characteristics of the structure with the aid of measured drawing projects. This study used a combination of architectural restoration and structural engineering. For Helvacılar Mosque, the study carried out the self-weight analysis, modal analysis, settlement analysis, response spectrum analysis, time history analysis using three real earthquake records in a finite element model. The aim of engineering research is to identify the present causes of damages in the structure. With the help of finite element analysis, the study put forward the essential repair and strengthening methods for Helvacılar Mosque to repair the damages observed in the structure, strengthen the structure, and obviate the causes of the damages based on the intervention methods offered in the guideline titled Earthquake Risk Management of Historical Structures issued by the General Directorate of Foundations.

    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.
