Estimation of seismic losses is a fundamental step in risk mitigation in urban regions. Structural damage patterns depend on the regional seismic properties and the local building vulnerability. In this study, a framework for seismic damage estimation is proposed where the local building fragilities are modeled based on a set of simulated ground motions in the region of interest. For this purpose, first, ground motion records are simulated for a set of scenario events using stochastic finite-fault methodolo...
Seismic damage assessment using synthetic ground motions: a case study for Erzincan
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (2015-10-14)
Estimation of seismic losses is a fundamental step for risk mitigation decision-making in urban regions. As the study region, Erzincan, a city on the eastern part of Turkey is selected which is located in the conjunction of three active faults as right lateral North Anatolian Fault, left lateral North East Anatolian Fault and left lateral Ovacik fault. Erzincan city center is in a pull-apart basin underlain by soft sediments that has experienced devastating earthquakes such as the 27 December 1939 (Ms8.0) ...
SEISMIC HAZARD ANALYSIS WITH RANDOMLY LOCATED SOURCES
Yücemen, Mehmet Semih (1994-03-01)
Demarcation of areal and linear seismic sources involves a certain degree of uncertainty and this should be reflected in the final seismic hazard results. The uncertainty associated with the description of the geographical coordinates of a source zone boundary is modeled by introducing the concept of 'random boundary', where the location of the boundary is assumed to exhibit a spatial bivariate Gaussian distribution. Here the mean vector denotes the best estimate of location and the variance reflects the ma...
Seismic hazard assessment for the North Anatolian and San Andreas faults based on random field models
Akkaya, AD; Yücemen, Mehmet Semih (1999-12-15)
The North Anatolian fault (NAF), located in northern Turkey and California's San Andreas fault (SAF) show remarkable similarities. A random field model, developed by the authors (Akkaya & Yucemen 1996) is utilized to compare the seismicity characteristics of the two faults on a statistical basis. The seismic hazard model is based on the level-crossing theory of random fields and considers the space-time correlations simultaneously and explicitly through the use of spatial and temporal scales of fluctuation....
Seismic Damage Assessment in Erzincan (Turkey) utilizing Synthetic Ground Motion Records
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (2017-01-09)
Loss estimation studies exercised for seismically active regions generally require fragility analyses to be performed which necessitate the use of ground motion records. These records could be ‘real’, i.e. recorded, acceleration time series or for regions with sparse ground motion data, ‘synthetic’ records consistent with the regional seismicity and produced using alternative simulation techniques. This study mainly concentrates on seismic damage estimation of Erzincan, which is a city on the eastern part o...
