Seismic and Structural Analyses of the Eastern Anatolian Region (Turkey) Using Different Probabilities of Exceedance

Abstract

Seismic hazard analysis of the earthquake-prone Eastern Anatolian Region (Turkey) has become more important due to its growing strategic importance as a global energy corridor. Most of the cities in that region have experienced the loss of life and property due to significant earthquakes. Thus, in this study, we attempted to estimate the seismic hazard in that region. Seismic moment variations were obtained using different types of earthquake magnitudes such as Mw, Ms, and Mb. The earthquake parameters were also determined for all provincial centers using the earthquake ground motion levels with some probabilities of exceedance. The spectral acceleration coefficients were compared based on the current and previous seismic design codes of the country. Additionally, structural analyses were performed using different earthquake ground motion levels for the Bingöl province, which has the highest peak ground acceleration values for a sample reinforced concrete building. The highest seismic moment variations were found between the Van and Hakkari provinces. The findings also showed that the peak ground acceleration values varied between 0.2–0.7 g for earthquakes, with a repetition period of 475 years. A comparison of the probabilistic seismic hazard curves of the Bingöl province with the well-known attenuation relationships showed that the current seismic design code indicates a higher earthquake risk than most of the others.

A Multidisciplinary Approach for the Vulnerability Assessment of a Venetian Historic Palace: High Water Phenomena and Climate Change Effects

“…In particular, concerning this last issue, the results of these analyses allow the identification of the possible formation of macro-elements [45,46] that behave independently from the rest of the building. For this reason, this approach could be properly applied in the field of seismic assessment at the territorial level, for historic centers and for single buildings (e.g., [2,[49][50][51][52][53]).…”

“…In general, parameters such as seismicity, faults and fault groups in the region, characteristics of the faults, the distance of the structure to the faults, earthquake history of the region, and the characteristics of the earthquakes are taken into account. In countries with high earthquake hazards, earthquake hazard maps are created by conducting various seismic zones (Özmen, 2012;Işık et al, 2021). In Turkey, until the last earthquake hazard map, a regional-based earthquake zones map was used on different bases.…”

“…It was deduced that the target top displacements expected from the structures were significantly changed. Lastly, the pre and postseismic performance of RC buildings was investigated by Isik et al [22] and Nemutlu et al [23], respectively. The former authors performed an earthquake hazard analysis of the Eastern Anatolian Region of Turkey using a performance-based seismic evaluation approach.…”
