Monastery of Stoudios, dated back to the reign of Eastern Roman Empire, is known to be the oldest surviving -albeit partially- religious building in Istanbul. During sixteen centuries, the building has been exposed to several earthquakes, fires and other minor disasters which have caused considerable damages and partial destruction in some of its sections. As a part of a general master plan for the structural condition assessment of historical buildings and monuments of Istanbul, this study aims to evaluate the seismic resistance of the monastery against future excitations. The expected failures and corresponding preventive/controlling repairs and strengthening measures will also be discussed in the article.


Structural Evaluation and Strengthening of Zeynelbey Tomb in Hasankeyf, Turkey
Türer, Ahmet (2010-10-08)
Hasankeyf historic settlement area is one the most important sites in southeastern Anatolia which dates back to the 15(th) century. Zeynelbey Tomb is a distinct cylindrical structure has a height of 9.6 m and with double domes extending to an overall height of 16.5m; however, the outer dome suffers from multiple and large vertical tension cracks threatening the overall structural stability and safety of the structure. A preliminary visual inspection and structural evaluation using analytical modeling was ca...

In Turkey, as well as in Balkan countries, examples of an extant housing tradition namely himis, which was formed during Ottoman period, can still be observed. In spite of minor local differences according to geographical locations, these Ottoman himis houses are distinguished with a number of common architectural and technical peculiarities that is worth to preserve. They have similar timber frame construction system with different infill materials. There are numerous reports claiming that the himis houses...
Seismic Resistance Evaluation of Traditional Ottoman Timber-Frame Himis Houses: Frame Loadings and Material Tests
Aktas, Yasemin Didem; Akyüz, Uğurhan; Türer, Ahmet; Erdil, Barış; Şahin Güçhan, Neriman (SAGE Publications, 2014-11-01)
Traditional Ottoman timber-frame houses ("himis") form the major part of the cultural heritage structures in Turkey. There are many studies in the literature regarding the seismic performance of himis houses, which claim that these structures have an inherent seismically resistant property. However, these studies lack a quantitative engineering approach and are based on observations made after contemporary earthquakes. This study presents the results of the seismic resistance evaluation of traditional Ottom...
Structural analysis, evaluation and strengthening of the temple of Augustus in Ankara
Uçak, Burak; Türer, Ahmet; Department of Civil Engineering (2016)
The temple of Augustus in Ankara has stood as a keeper and witness of the region’s historical past for hundreds of years from the time of Galatians and Romans. Bearer of the sign of ancient times not only as carved on its walls but also with its architectural and structural features, this monument now is in the need of engineering intervention to cope with the risk of collapse. Consequently, its structural behavior was analyzed using nonlinear discrete element modeling and linear finite element modeling and...
Repair Phases of Suleymaniye Complex in Damascus
Şahin Güçhan, Neriman; Kuleli, Ayşe Esin (Middle East Technical University, Faculty of Architecture, 2018-6-28)
Süleymaniye Complex in Damascus, built on the bank of Barada River as the last stop before the desert on the pilgrimage route extending from the Balkans to Mecca, is one of the works of Hassa Chief Architect Sinan, which was designed according to the basic principles of the Ottoman classical period architecture, and built between 1554 and 1559. Many research has been carried out on the historical and architectural features of the complex, which is composed of the mosque that is also known as the “Takiyah Sü...
