Simulated ground motions have been used for both hazard and engineering analyses recently, particularly in areas with significant seismic activity and insufficient seismic networks. From an engineering point of view, one important task is to evaluate 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 potential events in Duzce (Turkey). The objective is to evaluate the efficiency of broadband ground motions for structural response simulation. The hybrid ground motion simulation framework presented herein is a combination of a discrete wavenumber finite element method for simulating low frequencies and stochastic finite fault method for the higher frequencies. The proposed technique is first validated by simulation of the 12 November 1999 Duzce earthquake (Mw=7.1) which occurred on North Anatolian Fault Zone, Turkey. Then, spatial distribution of simulated peak ground motion intensities in terms of PGA and PGV values are obtained for the 1999 Duzce (Mw=7.1) earthquake. In addition, ground motion intensities of the simulated records are compared against Ground Motion Prediction Equations (GMPE) derived with global and local datasets. Comparison of the results demonstrates that there is a good match between the simulated and real records. Next, to evaluate the simulated records in building response estimation, nonlinear time history analysis of a typical reinforcedconcrete multi-degree-of-freedom structure is performed with both real and simulated records of the 1999 Duzce earthquake in the OpenSees platform. The results reveal that reasonable predictions can be made regarding the dynamic response of structures using the records simulated with the approach presented.

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...
Seismological and Engineering Demand Misfits for Evaluating Simulated Ground Motion Records Karim Zadeh Naghshineh, Shaghayegh (2019-11-01) Simulated ground motions have recently gained more attention in seismology and earthquake engineering. Since different characteristics of waveforms are expected to influence alternative structural response parameters, evaluation of simulations, for key components of seismological and engineering points of view is necessary. When seismological aspect is of concern, consideration of a representative set of ground motion parameters is imperative. Besides, to test the applicability of simulations in earthquake ...
Use of Alternative Site Amplification Models in Simulations and Uncertainty Analysis Muratoğlu, Gamze; Askan Gündoğan, Ayşegül; Karim Zadeh Naghshineh, Shaghayegh (null; 2020-12-16) Ground motion simulations are used for earthquake engineering purposes as alternative to real records. The accuracy of the simulations is evaluated using misfit functions in terms of seismological and structural parameters computed for real and observed ground motions. Among all input parameters used in the simulations, site amplification factors carry significant uncertainty. Alternative approaches to estimate site amplifications include generic site amplifications based on quarter-wave-length technique, e...
Numerical modeling of 3 february 2002 Çay earthquake : ground motion simulation and intensity distribution Can, Gizem; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2014) In seismically active regions strong ground motion estimation is essential for several purposes ranging from seismic design and analyses to disaster management. In regions of sparse seismic networks or seismic activity with long return periods, simulations become essential. This is particularly true when not only the peak ground motion parameters but the full time series of acceleration is required for earthquake engineering purposes. These simulations provide not only the earthquake engineering parameters ...
