Aspendos Theatre still stands in fairly good condition although it has been constructed about 2200 years ago in Serik village of Antalya, Turkey. Aspendos Theatre is one of the most valuable historical buildings in Turkey. The fact that the structure had overcome numerous possible earthquakes during its lifespan in Antalya and located in second degree earthquake zone, makes the subject an interesting research topic. The earthquake analysis of Aspendos Theatre was conducted using أSpecification for Structures to be Built in Disaster Areasؤ code and stress levels are investigated using 3D FE modeling. Also, the resonance state of the theatre under sound induced forces due to concerts and exhibitions performed in the theatre has been examined. Structural identification is performed to obtain certain structural characteristics by comparing experimentally measured and analytically obtained natural frequencies. The analytical model is constructed using solid members and the analysis is performed by using SAP2000 software. The elastic modulus of conglomerate used as building blocks in the Theatre is taken as 2350 MPa based on the experimental and analytical studies. The compressive and tensile strength of the theatre wall material is taken as 12 MPa and 1.2 MPa, respectively based on the previous studies conducted on conglomerate. When the maximum stress levels under combined effect of response spectrum and dead load analyses are examined, the level of compressive stress is found to be about 60% of the compressive strength. On the other hand, the tensile stresses developing at upper corners and bottom middle parts of the stage wall and mid-height central location of the exterior wall (on the vicinity of the front door) are calculated to be about 6.6 MPa, which are more than the assumed tensile strength. It has also been calculated that the level of sound that generates

In plane seismic strengthening of brick masonry walls using rebars Erdoğdu, Murat; Türer, Ahmet; Department of Civil Engineering (2008) About half of the total building stock in Turkey is masonry type building. Masonry buildings in Turkey, especially in rural areas, are constructed without any engineering knowledge mostly by their own residents. They generally have heavy roofs. Masonry type buildings also have thick and heavy wall materials. Heavy roof and wall material generate large inertial forces in the case of an earthquake. Brittle failure of walls leads to total failure of whole system followed by sudden collapse of heavy roof. The a...
Strengthening of reinforced concrete frames by custom shaped high strength concrete masonry blocks Arslan, Güray; Polat, Mustafa Uğur; Department of Civil Engineering (2009) Located on one of the highly active seismic fault systems in the world, the building stock in Turkey is mainly composed of reinforced concrete frames with 4-5 stories. Due to design and construction deficiencies resulting from the use of unqualified personnel and insufficient supervision, many of these buildings lack lateral stiffness, ductility and strength. For many structures, there is a need to alleviate these deficiencies by means of some rehabilitation techniques prior to earthquakes. One approach als...
Development of a stability analysis program for block type quay walls and comparison of block placing methods Nergiz, Cengiz; Ergin, Ayşen; Department of Civil Engineering (2010) Block type quay walls are commonly used as berthing structures both in Turkey and worldwide. In this study, stability analysis of block type quay wall is carried out using pseudo-static method. A computer program named QSAP (using Excel spreadsheet) has been developed for the design of block type quay walls. QSAP has been prepared based on the rules of Turkish Seismic Design Codes for Coastal Structures, 2008. Reliability of this program is verified by a comparative study of Derince Port block type quay wal...
Seismic Assessment of Monastery of Stoudios (Imrahor Mosque) in Istanbul Kucukdogan, Bilge; Kubin, Josef; Ünay, Ali İhsan (2010-10-08) 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...
Seismic upgrade of deficient reinforced concrete frames using external systems Özkök, Mustafa Emre; Binici, Barış; Department of Civil Engineering (2010) There is a large building stock in seismic regions of Turkey that require seismic upgrades. In order to minimize the disturbance to occupants and not to intervene with the functioning of the building, external strengthening methods can be preferred among different alternatives. This study reports the experimental findings on the upgrading of deficient reinforced concrete frames with external installed structural components. Specimens strengthened with an externally reinforced concrete shear wall, external s...
