Ground-motion prediction equations (GMPEs) for spectral accelerations have traditionally focused on the range of response periods most closely associated with the dynamic characteristics of buildings. Providing predictions only in this period range (from 0.1 to 2 or 3 s) has also accommodated the assumed limitations on the usable period range resulting from the processing of accelerograms. There are, however, engineering applications for which estimates of spectral ordinates are required at shorter response periods. Recent work has demonstrated that high-frequency spectral ordinates are relatively insensitive to record processing, contrary to previous assumptions. In the light of this finding, additional regressions are performed to extend a recent pan-European GMPE to higher response frequencies. This model and others that also include coefficients for spectral ordinates at several high response frequencies are used to explore options for interpolating coefficients for equations that do not provide good coverage in this range. The challenges and uncertainties associated with such interpolations are discussed. The paper concludes that a set of standard response frequencies could be usefully established for future GMPEs.

Importance of Degrading Behavior for Seismic Performance Evaluation of Simple Structural Systems Erberik, Murat Altuğ (Informa UK Limited, 2011-01-01) This study focuses on effect of degradation characteristics on seismic performance of simple structural systems. Equivalent single degree of freedom systems are used for which the structural characteristics are taken from existing reinforced concrete (RC) frame buildings. Simulation of degrading behavior is achieved by considering actual experimental data. To obtain the seismic response of degrading structural systems, two different approaches are used: inelastic spectral analysis and fragility analysis. Ac...
Empirical ground-motion models for point- and extended-source crustal earthquake scenarios in Europe and the Middle East Akkar, S.; Sandikkaya, M. A.; Bommer, J. J. (Springer Science and Business Media LLC, 2014-02-01) This article presents the latest generation of ground-motion models for the prediction of elastic response (pseudo-) spectral accelerations, as well as peak ground acceleration and velocity, derived using pan-European databases. The models present a number of novelties with respect to previous generations of models (Ambraseys et al. in Earthq Eng Struct Dyn 25:371-400, 1996, Bull Earthq Eng 3:1-53, 2005; Bommer et al. in Bull Earthq Eng 1:171-203, 2003; Akkar and Bommer in Seismol Res Lett 81:195-206, 2010)...
Site-Specific Design Spectra for Vertical Ground Motion Gülerce, Zeynep (SAGE Publications, 2011-11-01) This paper contains ground-motion prediction equations (GMPEs) for the vertical-to-horizontal spectral acceleration (V/H) ratio, and the methods for constructing vertical design spectra that are consistent with the probabilistic seismic hazard assessment results for the horizontal ground motion component. The GMPEs for V/H ratio consistent with the horizontal GMPE of Abrahamson and Silva (2008) are derived using the Pacific Earthquake Engineering Research Center's Next Generation of Ground-Motion Attenuatio...
Technical Note: Practical Challenges Facing the Selection of Conditional Spectrum-Compatible Accelerograms Ay, Bekir Özer; Sullivan, Timothy John (Informa UK Limited, 2017-01-01) There are various possibilities for the selection and scaling of ground motions for advanced seismic assessment of buildings using nonlinear response-history analyses. As part of an on-going project looking at building-specific loss assessment in Italy, this article highlights a number of challenges currently facing the use of conditional spectra for ground motion selection in practice, essentially related to the limited amount of seismic hazard information that is publicly available. To illustrate the poin...
Development of Fragility Curves for Single-Column RC Italian Bridges Using Nonlinear Static Analysis Perdomo, Camilo; Monteiro, Ricardo; Sucuoğlu, Haluk (Informa UK Limited, 2020-05-07) The main objective of this study is to assess the accuracy and suitability of Nonlinear Static Procedures (NSPs) in the development of analytical damage fragility curves for seismic risk assessment of large portfolios of Reinforced Concrete (RC) bridges. Seven NSP approaches, from widely used single-mode conventional pushover-based approaches to the more rigorous multi-mode conventional or adaptive pushover-based procedures are implemented. By systematically comparing fragility curve estimations in terms of...
