Recent studies have shown that simulated ground motions could be utilized to determine the seismic vulnerability of structures where there are limited number of real ground motion records compatible with seismological characteristics of the area of interest. Among various simulation techniques, stochastic finite-fault methodology is believed to practically simulate realistic broadband records including the frequencies which affect the built environment. This study aims to compare the main characteristics of stochastically `simulated' records in terms of major intensity measures along with corresponding `real' records which are consistent with the probable hazard and seismotectonics of the areas studied. The intensity measures considered include Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), a modified version of Acceleration Spectrum Intensity for consideration of period range of 0.1-2.5s (ASI), Housner Intensity (HI), Velocity Spectrum Intensity (VSI), Cumulative Absolute Velocity (CAV), Arias Intensity (Ia), Significant Duration (td). `Simulated' records generated for two different regions in Turkey (Erzincan and Duzce) along the North Anatolian Fault Zone (NAFZ) are used for comparisons against the corresponding `real' records. Comparisons of seismic intensity measures based on real and simulated data are made both visually and statistically.

COMPARISONS OF ALTERNATIVE SEISMIC INTENSITY PARAMETERS FOR SELECTED SETS OF REAL AND SIMULATED GROUND MOTION RECORDS Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Yakut, Ahmet (2018-09-02) In areas where inadequate number of regional real ground motion records are available, seismic vulnerability of structural systems can be assessed alternatively using simulated records generated for potential scenario events at the region of interest. However, the main question of interest herein is the accuracy of these simulated records. Thus, this study aims to obtain and compare alternative seismic ground motion intensity measures for the selected sets of real and simulated ground motion records. For th...
Evaluation and selection of ground motion intensity measures for nonlinear seismic demand and fragility analysis of MDOF systems Kadaş, Koray; Yakut, Ahmet; Department of Civil Engineering (2021-5-21) In performance-based seismic design methodology, intensity measures are thought to be key parameters of ground motion records that relate the seismic hazard levels with the structural response or damage. Therefore, it is important to identify efficient intensity measures that are capable of reducing the variability in seismic demand predictions. There exist several simple-to-advanced scalar and vector ground motion intensity measures; however, the literature is limited in the number of comparative studies i...
Analysis Methods for the Investigation of the Seismic Response of Concrete Dams Aldemir, Alper; Yilmazturk, Sema Melek; Yucel, Ali Riza; Binici, Barış; Arıcı, Yalın; Akman, Altug (2015-01-01) The consideratiOn of the dam-foundation-reservoir interaction is extremely important for estimating the seismic response of concrete gravity dams. Moreover, nonlinear analysis may be required for determining the possible risk associated with dams. In order to address these issues, DSI recently published the "Guidelines for Seismic Design of Concrete Dams". Authors who have contributed to the preparation of this document provide a perspective on the seismic safety/design of concrete dams and structural analy...
Experimental evaluation of geomembrane / geotextile interface as base isolating system Taheri Bonab, Amin; Gülerce, Zeynep; Kalpakcı, Volkan; Department of Civil Engineering (2016) The objective of this study is to evaluate the effect of the composite liner seismic isolation system on the seismic response of small-to-moderate height structures. For this purpose, a building model with the natural frequency of 3.13 Hz (representing 3-4 story structures) was tested with and without the addition of composite liner system using the shaking table test set-up by employing harmonic and modified/ scaled ground motions. Experiment results showed that the composite liner seismic isolation system...
Broadband Ground Motion Simulation Within the City of Düzce (Turkey) and Building Response Simulation Ozmen, Ekin; Karim Zadeh Naghshineh, Shaghayegh; Askan, Aysegul (Springer Science and Business Media LLC, 2020-05-01) In areas with significant seismic activity and insufficient seismic networks, simulated ground motions are required for both seismic hazard and engineering analyses. One important task is evaluating the efficiency of the simulated records in building response estimation. In this study, a hybrid ground motion simulation framework is presented to obtain broadband ground motion time histories of a past major earthquake in Düzce (Turkey). The hybrid ground motion simulation framework presented herein is a combi...
