Article Citation - WoS: 3Citation - Scopus: 5Helenistik Kulelerde Yanal Yüke İlişkin Düzlem İçi ve Düzlem Dışı Duvar Davranışının Duvar Profilleri ve Açıklık Düzenlerine Bağlı Olarak İncelenmesi(Gazi Üniversitesi, 2020) Gençer, Funda; Turan, Mine; Aktaş, EnginDry masonry wall profiles constructed without using bonding material between blocks are encountered in different building types dated to Greek, Hellenistic and Roman periods. Depending on development of earthquake experiences, dry masonry wall profiles vary in terms of wall thickness, number of layers, relationship of layers and size, form, organization and relationship of blocks. In this study, the construction details increasing the structural strength in watch towers constructed in Hellenistic Period are aimed to be determined. This study is limited with investigation of effect of wall profiles and opening organizations on in-plane and out-of-plane wall behaviors under lateral loading. Primarily, wall profiles and opening types of dry masonry towers in ancient Caria, Pamphylia and Cilicia regions, that have not lost authenticity and integrity or had information about their authentic form, were documented. By using gathered data, hypothetic towers with different wall profiles and opening types are designed. To determine in-plane and out-of-plane wall behavior of hypothetic towers, simulation of quasi-static tilt analysis based on equilibrium were carried out, and form changes at walls and collapse angles of towers were identified. Wall profile and opening properties effecting on structural strength under lateral loading were determinedd.Article Citation - WoS: 3Citation - Scopus: 3Structural Vulnerability of Ancient Dry Masonry Towers Under Lateral Loading(Elsevier, 2020) Gençer, Funda; Hamamcıoğlu Turan, Mine; Turan, Mine; Aktaş, Engin; Aktaş, EnginUnderstanding how the original characteristics contribute to the structural behaviour of antique structures should be the initial stage of planning for conservation work. This study aims to identify the structural behaviour of dry masonry towers under lateral loadings, so that the decision-making process when determining their restoration can be adequately supported. Dry masonry towers in ancient Caria, Pamphylia, and Cilicia Regions are examined. Each of these three areas have very different seismic characteristics. A hypothetical testing process was designed by combining different characteristics from each of the towers. As a result, the characteristics affecting the structural resistance were determined as; the staggering ratio, the stone depth, the ratio between block length and height, the proportional relationship between height and length, the area, number and position of openings, and the distribution of header stones. These characteristics all interact together to determine the failure mechanism; so, understanding this interaction is critical when considering conservation. © 2020 Elsevier LtdArticle Citation - Scopus: 5Mimari Fotogrametri Alanındaki Çağdaş Gelişimlerin Değerlendirilmesi(Gazi Üniversitesi, 2004) Turan, MineSayısal (dijital) veya analog (fotoğrafik) görüntüler üzerindeki bilgilerin, mimari nesnelerin ölçekli görsel belgelerinin elde edilmesinde kullanılmak üzere değerlendirilmesi tekniklerinin bütününe mimari fotogrametri denilmektedir. Tarihi uygulamalarda genellikle ayrıntılı cephe çizimleri ile belgeleme sonuçları sunulurken, çağdaş olanaklar, koruma uzmanı mimarın gereksinim duyduğu çözümleyici görselleştirmelerin sunumuna da olanak vermiştir. Artık fotogrametri ile belgelenen tarihi binalar; bilgisayar ortamında hazırlanan üç boyutlu modelleri, çeşitli perspektifleri ve tematik bilgilerin döküldüğü ayrıntılı haritaları ile incelenebilmektedirler. Etkileşimsel çoklu ortamda gerçekleştirilen sunumlar da yapılabilmektedir. Bu sunumlara olanak veren yüksek geometrik hassasiyetteki filmli ve dijital fotoğraf makineleri, yüksek çözünürlükteki tarayıcılar ve görüntü değerlendirme yazılımları hızla geliştirilmektedir.

It requires an integrated representation of various types of information for understanding and management prior to the decision-making process of conservation. This requirement is a twofold manner consisting of representation and management processes. There exists a variety of approaches for representation of heritage objects in digital three-dimensional (3D) environment, but the selection of the appropriate one according to the needs is crucial. On one hand, there have been recently great attempts to adopt Building Information Modeling (BIM) for historical buildings. Nevertheless, the related works in the topic focus mainly on pre-processing of data, such as the integration of born-digital material into a BIM environment and the creation of parametric objects according to historical building characteristics. As the information management of a historical building requires enhanced attribute management and integration of different datasets, further investigation on the BIM capabilities in management terms is crucial. On the other hand, Geographical Information Systems (GIS) have great potentials in exploring spatial relationships, but their potential in 3D representation is still somehow limited. The paper reviews and evaluates the roles of BIM and GIS, highlighting their advantages and disadvantages for integration, retrieval and management of heterogeneous data in the context of historical buildings. © 2013 Copernicus.

It takes into consideration the vernacular house type of Alaçati, Izmir, Turkey and defines the appropriate techniques to be used in the conservation aimed analytic recording process. The prismatic house masses at human scale, with plain façade orders and orthogonal plan layouts at this settlement can be recorded fast and accurately with close-range digital photogrammetry. The concepts of mapping should be utilized for the representation of analtic data. Within this frame, a 19th century house located in the urban conservation site of Alaçati is to be presented as the case study. © 2007 International Society for Photogrammetry and Remote Sensing.

Thus, it is important to shed light on any given historic building’s chronological information by means of restitution, that is, the descriptions of different (re)compositions of a building for different historical states. However, the representation of information beyond the geometric, spatial, and physical characteristics of a historic building carries a crucial importance in the holistic understanding of historical changes. This requirement consists of representation, archival, assessment, and management aspects. Nevertheless, covering all these aspects is still quite challenging. Thus, three-dimensional (3D) visualization in digital platforms is considered, which indeed seems to be the most desirable way today. This article proposes a methodology through adopting an approach based on the Geographical Information System (GIS) and further develops a digital “container” as a 3D digital model for the archiving of a building’s chronological information. This does not only cover the geometric and spatial aspects, but also the historical resources and their reliability. The paper concludes that the developed prototype may lessen the future investigation effort of heritage specialists by making the chronological information of a historical building more integrated and coherent, through increased readability, accessibility, and visibility. This, in turn, supports the planning of restoration projects, as well as provides a static and comprehensive archive. © 2018 by the authors.

Case studies are selected from provinces of Manisa, Turkey, namely, Çarşı in Salihli with its new urban development and Pazaryeri in Gördes that is abandoned and currently considered as an archaeological site. Literature review, archive research, historical research, comparative study, and site survey are carried out to evaluate the urban development of site neighborhoods with a retrospective perspective. An approach presenting the effects of urban transformations on the cultural asset values of the historic neighborhood centers is proposed. The cases reveal that the urban aesthetic is nearly all lost today, but the holiness of each site preserves its authenticity while the historic land use is sustained. Their preservation problems are lack of maintenance and abandonment due to disasters, illegal interventions, inappropriate development plans, and unsuitable restoration approaches. The principles proposed for managing these historic environments consider their cultural asset values in relation to urban history, development of coherent strategies for their presentation, and participation of all actors to their preservation and development. © 2020 The AuthorsArticle 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.Article Citation - WoS: 5Citation - Scopus: 2The Masonry Techniques of a Historical Bridge in Hypokremnos (i̇çmeler)(Middle East Technical University, 2017) Uygun Gençer, Funda; Turan, MineThis study focuses on characteristics of a historical bridge in Içmeler, Urla, Izmir. Urla, a historical settlement on the west of Izmir, has been part of a commercial network between Karaburun, çesme and Anatolia throughout history. The aim is to understand the construction technique and material usage in Hypokremnos Bridge and identify a possible sequence of the original construction. The linear bridge was constructed by using masonry technique. It has three openings with various sizes and supported with rounded arches. The bridge wall is crowned with a road way making a crest at its center a inclined façade. This study is composed of four phases; documentation, analysis of construction technique and material usage, historical evaluation and restitution. In the first phase, by using Tgi3D Su Photoscan 2.13 and Trimble SketchUp 2013 software, three dimensional model was prepared. Visual analysis of construction technique and material usage was carried out and the mortar sample from the bridge was investigated in the conservation laboratory in the second phase. Three dimensional manual photogrammetric documentation of the historical bridge has provided the advantage of conceiving many constructional details. This condensed observation of constructional features supported with comparative study on historical bridges in Anatolia has revealed that the elements and composition of the studied bridge presents Roman characteristics, but the masonry techniques used recall those of Turkish period. The detailed data about structural system gathered from different locations of the bridge was used for the production of reconstitution of system detail. Reconstitution model of the bridge was produced by using reconstitution of system detail. To identify construction phases of the bridge, literature survey was carried out. According to structural elements and composition of the bridge, it is thought to be constructred in Roman Period, however, both the randomness in the composition of the rough cut lime stones used in the outer shells of the bridge wall, and lack of system in the form and color composition of the cut sand stones in the arches and the sea façade may be interpreted as an end result of a comprehensive repair on total reconstruction in the Turkish period.Article Citation - WoS: 1Citation - Scopus: 1Photogrammetric Evaluation Options of an Ancient Monument for Different Survey Levels(Elsevier Ltd., 2016) Uygun, Funda; Turan, Mine; Ocalı, OganRecently, for the purpose of data management, more advanced digital data are required for different survey levels of irregular ancient monuments. For irregularly formed monuments and amorphous surfaces, 2D photographs and 2D measured surveys are inadequate to illustrate the condition of the building for condition reports or relationships between components and materials for structural surveys and conservation decisions, especially in archeological remains. However, image-based documentation techniques can be used as simple tools for different types of surveys due to their ease of use and fast and economical properties. Therefore, the aim of the study is to test multi-image photogrammetric documentation techniques to improve and standardize visual data appending condition reports and further detailed reports regarding conservation of irregular ancient monuments.In the literature, there are many studies about image-based documentation techniques. However, the innovation of the study is to provide an improvement of the pipeline of condition and structural surveys of irregular ancient monuments by making use of photogrammetric techniques.In order to measure the effects of the relationship between the type of documentation technique and survey level on the photogrammetric documentation process of an ancient monument, a series of experiments were designed and the results compared. For this purpose, automated image orientation packages Autodesk 123D and Photosynth and manual image orientation package Tgi3D were evaluated in terms of process time, reliability and level of detail to identify appropriate techniques for different survey levels.This study proved that documentation of the structural characteristics of ancient monuments can be achieved successfully with the Tgi3D package, which has manual workflows. The documentation results might support structural intervention decisions. The 3D models based on automatic workflows might support a preliminary condition survey, since their production takes a relatively short time and scaled models are acceptable for identifying mass characteristics.
