In this study, earthquake loads are investigated statistically and compared with the nominal earthquake loads calculated according to the Turkish Earthquake Code, namely: "Specifications for Structures to be Built in Earthquake Areas". For this purpose, the "actual" mean load values estimated from statistical methods and the nominal load values computed according the Seismic Code are compared, with respect to some variations in the basic parameters, such as the importance factor, building height, site coefficient, seismic zone and seismic load reduction factor. In addition to the data compiled from different regions of Turkey, the published data and information in the foreign literature are also used in the determination of the earthquake load statistics. Although the dead and live loads acting on a structure are independent of the geographical location of the structure, environmental loads, such as earthquake loads are highly dependent on the location of the structure. Accordingly, for the assessment of statistical parameters associated with earthquake loads, twelve different locations which can represent the different seismic zones of Turkey as accurately as possible are chosen. As a result of the code calibration procedure considered in this study, it is observed that the load values obtained from the Turkish Seismic Code may overestimate or underestimate the actual seismic loads in some of the seismic zones.

Guidelines for structural health monitoring systems on tall buildings and a case study Gümüş, Oğuzhan; Çelik, Ozan Cem; Department of Civil Engineering (2021-2-15) The new Turkish Building Earthquake Code requires real-time monitoring of the structural response of buildings of Earthquake Design Class 1 and 2 that are taller than 105 m. Structural health monitoring (SHM) systems on tall buildings have to comply with the SHM Guidelines by the Disaster and Emergency Management Presidency of Turkey, developed as part of two research projects that were undertaken at METU and Bogazici University. Two tall buildings in Izmir and Istanbul, respectively, were instrumented as c...
Comparison of mean site-specific response spectra in Turkey with the design spectra of AASHTO Mestav Sarıca, Gizem; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2014) Seismic design of bridges is a significant problem for all seismically-active countries including Turkey which has gone through recent destructive earthquakes. Bridges are important elements of transportation and their robustness is important in the aftermath of major earthquakes. Turkish engineers currently employ a modified version of AASHTO (American Association of State Highway and Transportation Officials) LFD Design Specifications for bridge design. Within the scope of a national project (TÜBİTAK 110G...
An evaluation of the 2019 seismic hazard map of Turkey on the basis of spectrum intensity Akansel, Vesile Hatun; Soysal, Berat Feyza; Kadaş, Koray; Gülkan, Hakkı Polat (null; 2019-10-11) Seismic hazard maps show the distribution of expected earthquake shaking levels that have a specific probability of occurrence for a region, and provide input for engineers to design structures that will withstand earthquake ground shaking. The 2019 Turkish Building Earthquake Regulation relies on an updated seismic hazard map that considers new source models and more recent ground motion prediction equations. The effect of the change in seismic hazard map that will directly affect the code-based seismic de...
Seismic fragilities for non-ductile reinforced concrete frames - Role of aleatoric and epistemic uncertainties Çelik, Ozan Cem (2010-01-01) Seismic fragilities are essential to earthquake loss estimation and performance-based earthquake engineering in regions of high seismicity. Construction practices for frames in regions of moderate seismicity are quite different, and such frames have received less attention in the literature. Fragilities for performance levels identified in recent seismic regulations are developed herein for reinforced concrete frames designed for gravity load in low-seismic regions using probabilistic non-linear finite elem...
Estimation of earthquake damage probabilities for reinforced concrete buildings Yücemen, Mehmet Semih (2003-05-13) Due to uncertainties involved both in the occurrence of earthquakes and in structural response, earthquake damage prediction has to be treated in a probabilistic manner. In this study two statistical methods are presented for the prediction of potential seismic damage to low and mid-rise reinforced concrete buildings in Turkey. These methods are based on the utilization of damage probability matrices and reliability theory. The damage data compiled during recent earthquakes that occurred in Turkey are used ...
