This study focuses on characteristics of a historical bridge in Icmeler, Urla, Izmir. Urla, a historical settlement on the west of Izmir, has been part of a commercial network between Karaburun, Cesme 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 facade. 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 facade may be interpreted as an end result of a comprehensive repair on total reconstruction in the Turkish period.

New building in historical settlement as an urban conservation problem : a case study in Tarsus
Bilgiç, Umut; Madran, Emre; Restoration in Department of Architecture (2004)
This thesis develops around the theme of new building problem in historical settlements. Rapid and uncontrollable urbanization due to industrialization and over dense population is resulting in the demolishment of the existing historical settlements in our country. Despite this change, as the main goal of conservation is to provide historical continuity, the existence of the new buildings in historical settings as the products of this process come out to be an urban conservation problem. The current regulat...
Seismic vulnerability of masonry structures in Turkey
Ceran, Hasan Burak; Erberik, Murat Altuğ; Department of Civil Engineering (2010)
This study focuses on the evaluation of seismic safety of masonry buildings in Turkey by using fragility curves. Fragility curves for masonry buildings are generated by two behavior modes for load bearing walls: in-plane and out-of-plane. By considering the previous research and site investigations, four major parameters have been used in order to classify masonry buildings with in-plane behavior mode. These are number of stories, strength of load-bearing wall material, regularity in plan and the arrangemen...

This thesis aims to examine the transformation of Yüksel Street-Konur Street intersection from a residential area into a public place by the effects of Mimarlar Odası (Chamber of Architects of Turkey) and Mülkiyeliler Birliği (Ankara University Faculty of Political Sciences Alumni Association) as two important civil society institutions located there. In the second half of the twentieth century, Ankara witnessed the unplanned development and deterioration of urban environment as a result of dramatic economi...
Tarihi Türk hamamlarının akustik nitelikleri: özgün hali ve bugünkü durumu
Tavukçuoğlu, Ayşe; Çalışkan, Mehmet (null; 2011-05-26)
Comprehensive studies are needed to discover the original acoustical features of historical Turkish baths and to keep their functioning together with their inherent characteristics for long periods of time. The main concern of the study wasthe discovery of original acoustical features the Kadı Hamamı(Diyarbakır) and Şengül Hamamı (Ankara), two 15thcentury historical baths belonging to the Ottoman period, and acoustical failures occurred in time due to the recent improper repairs. The historical ...
