    Seismic Vulnerability Assessment of Bergama Bedesten
    (Izmir Institute of Technology, 2022) Demir, Hatice Ayşegül; Turan, Mine; Aktaş, Engin
    This study aims to document Bergama Bedesten with emphasis on its construction technique and material usage; and assess its structural condition for future seismic action through numerical analysis. The monument (15th -16th century) is unique among the historical trade buildings at the center of Bergama, İzmir. It is revealed that the structure is a rare example by the use of plane triangles as transition elements, the oculi placement in domes, and the thickening application at parts where load-bearing arches integrate into the walls and at the corners. In order to investigate the vulnerability of the building, numerical analysis using the finite element method was conducted in ANSYS software. According to the Turkey Building Earthquake Code (2018), single-mode equivalent earthquake analysis considering the horizontal elastic design spectrum of the site was carried out for x and y directions, separately. The maximum principal stress concentration locations obtained through analyses point vulnerable zones. These were specifically observed on load-bearing arches, on some plane triangles, on the transition zones, at dome parts close to the transition zone and peak level, at the parts where arches integrate to the walls, around top windows, on the west entrance door arch, and on a secondary door arch in the north wall. The method comparing the structural failure mapping and visual structural alterations analysis of architectural restoration with finite element model results, emphasizes that some damaged or altered portions in the current state are in seismically vulnerable spots. Some precautions, further studies and interventions were suggested for these locations.

    Restoration and Presentation of Byzantine Defense Structures in Cilicia
    (01. Izmir Institute of Technology, 2021) Kenar, Aylin; Turan, Mine
    The aim of this study is to evaluate current restorations and presentations of Byzantine defense structures in terms of sustaining and enhancement of the cultural heritage values and their success in solving conservation problems. So, better management of future interventions may be possible. Case study approach was undertaken: Three castle ruins in Cilicia, Turkey were focused on: Yılan and Feke castles and Kızkalesi in Korykos. The cases are located in the present-day rural areas. They are restored recently. The study consists of literature review, site survey, documentation and analysis of geographic characteristics, historic background, morphologic characteristics, construction technique and material usage and conservation activities of the case studies, identification of the cultural heritage values and conservation problems before and after interventions at the landscape, site and building scales; and discussion of the effects of the interventions on values and problems in comparison with case studies from abroad. As a result, it was determined that interventions were either unsystematic or implemented more than necessary. There is lack of a holistic approach for interventions. While some portions were intervened, others were left in-situ without any interventions. There is a tendency for reconstruction and reintegration in general. It was seen that current interventions either sustain already accumulated cultural heritage values or they have negative impact on them. Consequently, enhancement of values is not observed. Meanwhile, some of the conservation problems were ignored.
