The effect of peak ground velocity (PGV) on single-degree-of-freedom (SDOF) deformation demands and for certain ground-motion features is described by using a total of 60 soil site records with source-to-site distances less than 23 km and moment magnitudes between 5.5 and 7.6. The observations based on these records indicate that PGV correlates well with the earthquake magnitude and provides useful information about the ground-motion frequency content and strong-motion duration that can play a role on the seismic demand of structures. The statistical results computed from non-linear response history analyses of different hysteretic models highlight that PGV correlates better with the deformation demands with respect to other ground motion intensity measures. The choice of PGV as ground motion intensity decreases the dispersion due to record-to-record variability of SDOF deformation demands, particularly in the short period range. The central tendencies of deformation demands are sensitive to PGV and they may vary considerably as a function of the hysteretic model and structural period. The results provided in this study suggest a consideration of PGV as a stable candidate for ground motion intensity measure in simplified seismic assessment methods that are used to estimate structural performance for earthquake hazard analysis.

Effect of near-fault ground motion and damper characteristics on the seismic performance of chevron braced steel frames Dicleli, Murat (Wiley, 2007-06-01) This study is aimed at comparing the seismic performance of steel chevron braced frames (CBFs) with and without fluid viscous dampers (FVDs) as a function of the characteristics of the near-fault (NF) ground motion and FVD parameters. For this purpose, comparative nonlinear time history (NLTH) analyses of single and multiple storey CBFs with and without FVDs are conducted using NF ground motions with various velocity pulse periods scaled to have small, moderate and large intensities. Additionally, NLTH anal...
PREDICTION OF SEISMIC ENERGY-DISSIPATION IN SDOF SYSTEMS NURTUG, A; Sucuoğlu, Haluk (Wiley, 1995-09-01) A simple analytical procedure is developed for calculating the seismic energy dissipated by a linear SDOF system under an earthquake ground excitation. The ground excitation is specified by its pseudo-velocity spectra and effective duration whereas the SDOF system is defined by its natural period of vibration and viscous damping ratio. However, the derived relationship for the energy dissipation demand under an earthquake excitation is sensitive neither to the viscous damping ratio nor the ductility ratio w...
Effect of isolator and ground motion characteristics on the performance of seismic-isolated bridges Dicleli, Murat (Wiley, 2006-02-01) This paper presents the effect of isolator and substructure properties as well as the frequency characteristics and intensity of the ground motion on the performance of seismic-isolated bridges (SIBs) and examines some critical design clauses in the AASHTO Guide Specification for Seismic Isolation Design. For this purpose, a parametric study, involving more than 800 non-linear time history analyses of simplified structural models representative of typical SIBs, is conducted. The results from the parametric ...
Influence of long-period filter cut-off on elastic spectral displacements Akkar, Dede Sinan; Bommer, Julian J. (Wiley, 2006-07-25) The effect of the long-period filter cut-off, T-c, on elastic spectral displacements is investigated using a strong ground-motion database from Europe and the Middle East. The relation between the filter and oscillator responses is considered to observe the influence of T-c for both analogue and digital records, and the variations with site classification, magnitude, filter order and viscous damping. Robust statistics are derived using the re-processed European data to generalize the effects of the long-per...
Generalized force vectors for multi-mode pushover analysis of torsionally coupled systems Kaatsız, Kaan; Sucuoğlu, Haluk (Wiley, 2014-10-25) A generalized multi-mode pushover analysis procedure was developed for estimating the maximum inelastic seismic response of symmetrical plan structures under earthquake ground excitations. Pushover analyses are conducted with story-specific generalized force vectors in this procedure, with contributions from all effective modes. Generalized pushover analysis procedure is extended to three-dimensional torsionally coupled systems in the presented study. Generalized force distributions are expressed as the com...
