Probabilistic Constant-Strength Ductility Demand Spectra

Journal of Structural Engineering, 2007
A procedure is presented to develop probabilistic constant-strength ductility demand spectra based on statistical analyses of the results of comprehensive dynamic time history simulations of bilinear single-degree-freedom systems. The procedure offers an approach to estimate both the mean and standard deviation of the ductility demand, given the ...

Effect of the orientation of records on displacement ductility demand

Canadian Journal of Civil Engineering, 2012
Effects of the ground motion record orientation on the estimated pseudo-spectral acceleration (PSA) have been investigated and reported in the literature; the statistics of the PSA along the major and minor principal axes differ from that for a random orientation. This is true for California as well as for Mexican records.

Ductility demand spectra for multiple near- and far-fault earthquakes

Soil Dynamics and Earthquake Engineering, 2010
Abstract This study presents ductility demand spectra for single degree of freedom (SDOF) systems under multiple near- and far-fault seismic ground motions. The main innovation has to do with the quantification of the seismic sequence effect directly into ductility demands, a phenomenon which has not been studied in the past.

A Novel Structure-Pulse Coupled Model for Quantifying the Column Ductility Demand under Pulse-Like GMs

Journal of earthquake engineering, 2021
A novel model is constructed to investigate the coupling effect of pulse period (Tp ) and peak pulse velocity (Vp ) on structural demands with the varied fundamental period (T1 ) under pulse-like ground motions.

Ductility Demand Spectra of the Self-Centering Structure Subjected to Near-Fault Pulse-like Ground Motions

Journal of earthquake engineering, 2021
This paper focuses on the ductility demand of self-centering structures with flag-shaped (FS) hysteretic behavior under near-fault (NF) pulse-like ground motions.

Ductility and inelastic deformation demands of structures

Structural Engineering and Mechanics, 2012
Current seismic codes require from the seismically designed structures to be capable to withstand inelastic deformation. Many studies dealt with the development of different inelastic spectra with the aim to simplify the evaluation of inelastic deformation and performance of structures. Recently, the concept of inelastic spectra has been adopted in the
