Probabilistic assessment of seismic damage for an individual building or a building stock in terms of fragility curves generally requires utilization of ground motion records either seismologically consistent with the probable hazard for the area studied or chosen arbitrarily without considering the seismological characteristics, but covering a range of intensity levels. In both alternatives, the analyst should select several records to be able to perform the probabilistic studies accurately. This condition might not be always satisfied for regions where there are limited number of seismologically consistent records available or for cases when there are less number of records available for high intensity levels. To compensate for this, region-specific stochastically simulated ground motions could be utilized. This study evaluates the suitability of simulated records in development of fragility curves for a typical mid-rise reinforced concrete (RC) moment-resisting frame sampled from existing Düzce buildings. The simulated records have been generated by using stochastic finite-fault methodology with regional seismicity parameters of Düzce. Utilizing a multi-degree-of-freedom model of the selected building, nonlinear time history analyses have been performed and fragility curves considering alternative intensity measures (i.e., PGV, ASI, HI and VSI) have been developed. To test the performance of the simulated records-based fragility curves, a set of ‘real’ records compatible with the seismological characteristics of the region was selected from NGA-West2 ground motion database of PEER, and ‘real’ records-based fragility curves were developed as well. The results have been displayed graphically to present the appropriateness of the simulated records in loss estimation studies.

A study on fragility analyses of masonry buildings in Erzincan (Turkey) utilizing simulated and real ground motion records
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (Elsevier BV; 2017-09-13)
Ground motion records are generally required to develop fragility curves which are utilized in seismic loss estimation studies for earthquake prone zones. These records could be 'real', i.e. recorded acceleration time series or 'simulated' records consistent with the regional seismicity and produced using alternative simulation techniques. This study mainly concentrates on development of fragility curves for masonry buildings located in Erzincan (eastern Turkey) using 'simulated' ground motion records and e...

Kadas, Koray; Karımzadeh, Shaghayegh; Askan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (null; 2018-06-25)

An Investigation of the Ground Motion Scaling Procedures for the Nonlinear Seismic Analyses of Concrete Gravity Dams
Soysal, BERAT FEYZA; Ay, Bekir Özer; Arıcı, Yalın (2019-07-03)
Seismic assessment of gravity dams is generally carried out using time history analyses. Scaling of the motions is commonly used; however, in contrast to buildings, the performance of scaling procedures at predicting the mean and reducing the dispersion in engineering demand parameters (EDPs) is not known. The main goal of this study is to assess the performance of different scaling procedures in predicting seismic demands on dams. The performance regarding the prediction of the damage and the required numb...
Derivation of analytical fragility curves using SDOF models of masonry structures in Erzincan (Turkey)
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (2020-02-01)
Seismic loss estimation studies require fragility curves which are usually derived using ground motion datasets. Ground motion records can be either in the form of recorded or simulated time histories compatible with regional seismicity. The main purpose of this study is to investigate the use of alternative ground motion datasets (simulated and real) on the fragility curves. Simulated dataset is prepared considering regional seismicity parameters corresponding to Erzincan using the stochastic finite-fault ...
Evaluation of the Ground Motion Scaling Procedures for Concrete Gravity Dams
SOYSAL, BERAT FEYZA; Ay, Bekir Özer; Arıcı, Yalın (Elsevier BV; 2017-09-13)
The seismic safety of dam structures is often evaluated using time history analyses conducted with a limited number of ground motions. The selection and scaling of the ground motions is usually the most effective factor determining the results of the safety assessment. The inherent variability in the ground motion as well as the difficulty of conducting the analyses for a large number of ground motions renders the selection as the most important factor in the analysis results. The guidelines for the nonline...
