Conference Object The Challenges and Advantages of Macro Modeling in Ansys Software for Seismic Vulnerability Assessment of Historic Masonry Structures(National Technical University of Athens, 2023) Demir, Hatice Ayşegül; Yücetürk, Kutay; Aktaş, Engin; Hamamcıoğlu Turan, MineThis study aims at creating an advancement guideline for a software which can be used for seismic vulnerability assessment of historic masonry structures by revealing the results of an experience related to the macro modeling of a historic masonry building. The case study structure is Bergama Bedesten (15th-16th centuries) located in Bergama, Izmir, Turkey. ANSYS software is used for the Finite Element Modeling of the structure. The seismicity at its location is determined and the structural response under lateral loads is obtained together with the dynamic characteristics. Mesh design, component creation according to the used material change in structural elements, contact surface identification, the arrangement of the stress scales, and result interpretation are realized. For these stages, the challenges are discussed with the solutions. The advantageous aspects of the software are explained. For the challenges, in mesh design, the ineffectiveness of cartesian method for some elements was detected and tetrahedrons method was chosen. In contact surface identification, the overlapping portions of structural components could not be detected by the software exactly, so the manual surface separation was realized. In the stress level interpretation, the lack of assignment for material limit strength values to the analysis scale was experienced and the addition of limit values was carried out. The scale also needs manual arrangement for the increase of interval numbers of stress values to emphasize vulnerable zones. This flexibility of scale to be arranged can be seen as an advantage, as well. The 3d section and axonometric view creation provide the presentation of stress changes at inner and outer surfaces of the structure which is another positive side. © 2023 COMPDYN Proceedings.

It aims to shed light on the actors of the building traditions of Barbaros, the process of knowledge transfer among builders, and the traditional know-how related to local building materials and construction techniques as intangible cultural heritage. The research method of this study includes literature review, site survey, and study of oral history. Literature sources provided the theoretical background and limited information related to the history of Barbaros. To understand the traditional building stock in Barbaros, site surveys were conducted in 2016, 2017, and 2020. An oral history study was done with the last living builders and the relatives of late builders. These narratives provided invaluable information for answering the research questions. The results of the study contribute to the conservation of intangible heritage by recording the know-how of the last bearers of traditional construction in Barbaros. This documented experience can be used in future restoration projects not only in Barbaros but also in surrounding settlements with the same traditional construction features. The results of the study are also remarkable in terms of revealing the importance of oral history in documentation studies.Article Traditional Dwellings of Gölde (i̇ncesu): a Rural Heritage in the Process of Change(Routledge, 2021) Eken, Esra; Kul, Fatma NurşenGölde, officially named İncesu, is a rural settlement located in Aegean Anatolia. Before the population exchange between Greece and Turkey in 1923, Gölde hosted both Orthodox Rum and Muslim Turkish communities. Despite out-migration since 1923, traditional life continued in the settlement with a small population that now comprises mostly elderly Turkish people. This paper aims to understand traditional Gölde dwelling units by analysing the influence of daily-life practices, customs, traditions and values through interviews with current locals and the oral testimonies of former Rum inhabitants. A site survey identified 136 traditional dwelling units, 68 of which are still inhabited. Site reconstruction analysis revealed the original condition of 90 dwelling units. These formed the primary focus of investigation. No major differences were found between houses originally belonging to the Rum and Turkish communities. However, the study identified significant adaptations of the dwelling units in line with changing socio-cultural conditions over time.Article Urban Protection And Renewal Dilemma: İzmir Mezarlıkbaşı(İstanbul Teknik Üniversitesi, 2021) Akpınar, Figen; Turan, Mine; Toköz, Özge DenizAt the beginning of the 21st century, efforts to preserve cultural heritage in historical settlements is a highly problematic and multi-faceted issue in Turkey. Al-though conservation legislation dates back to 60 years ago, heritage conservation has not been internalized and accepted in the wider part of society, and, has not established a sound political foundation. On the other, however, there is also a lack of integrated land-use planning and management. The purpose of this study is to present the difficulties of dealing with the conservation, renewal, and regeneration for heritage areas in the historic core of İzmir, Mezarlıkbaşı-Kemeraltı, as well as to discuss the intrinsic physical qualities, dynamic characters and diversity of community groups with a view of new spatial agenda. The objective of the study is therefore twofold: 1) documentation of the physical characteristics and values for understanding the place; 2) to evaluate incorporating integrated strategic planning and management approach pointing the need for incorporating, leadership, partnership, integration and inclusion as a policy guideline for the safeguarding the heritage area. Our findings show that the Municipality of İzmir has made a significant attempt as TARKEM’s leadership position, which has succeeded in attracting national and international interest in Kemeraltı and creating opportunities for the future, but partnership (operation), management (structure) and inclusion (its processes) still lack. Community groups are not seen as part of the planning activities and planning has been remote, fragmented and exclusively missing an integrated planning management approach. © 2021, Istanbul Teknik Universitesi, Faculty of Architecture.

For this purpose, their basic physical properties, raw material compositions, mineralogical and microstructural properties were determined by X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy coupled with X-Ray Energy Dispersive Spectroscopy. Analysis results indicated that the binder of the mortars composed of lime and fine aggregates have compact and uniform structure. The mortars are of low density and high porosity were produced from high calcium lime containing magnesium and natural aggregates. The lime and aggregate ratios were between 3/4 - 5/2 by weight and the aggregates with particle sizes greater than 1mm. composed the largest fraction of the aggregates. Lime composed of small size of micritic crystals due to use of aged lime puny. Aggregates were natural and mainly composed of quartz, albite, diopside and amorphous silica that may derived from the use of volcanic ash as pozzolans.Article Citation - WoS: 7Citation - Scopus: 6Documentation of Historic Structures for the Assessment of Heritage Characteristics(Locke Science Publishing Company Inc., 2011) Turan, Mine; Akbaylar, İpekCorrect identification of heritage characteristics is a prerequisite for the conservation of historic structures. This study summarizes the developments in image-based documentation techniques and explores a way of combining them with conventional documentation techniques for architectural conservation. The processes of architectural photogrammetry and pictorial photography help the architect-conservator examine the many details of architectural heritage, making the assessment of heritage characteristics easier. Nevertheless, site observations and historical research are indispensable tools that support the evaluation process. A 19th centwy Ottoman church in western Turkey has been documented by combining the above techniques. Scaled drawings, a 3D model, maps on rectified image mosaics, and image albums make it possible to perceive the spatial qualities and conception of the original construction techniques, together with their alterations. The assessment results are presented in thematic tables with links to visual documents, and the heritage values and conservation problems of the church are clarified. Finally, this study illustrates one example of a successful heritage assessment leading to a conservation design.
