Optimal ground motion intensity measure for long-period structures
Measurement Science and Technology, 2015This paper aims to select the most appropriate ground motion intensity measure (IM) that is used in selecting earthquake records for the dynamic time history analysis of long-period structures. For this purpose, six reinforced concrete frame-core wall structures, designed according to modern seismic codes, are studied through dynamic time history ...

In this study, we quantify the reduction in total sigma (sigma(total)) of the Turkish ground-motion predictive models by partially removing the ergodic assumption. By partitioning residuals into four components: repeatable source-specific and site-specific deviations from the population mean as well as site-corrected within-event and source-corrected ...

In Performance-Based Seismic Design, the uncertainty in the estimation of the structural damage is related to the “efficiency” of the intensity measure, IM, adopted to describe the site-specific seismic hazard. Moreover, the choice of an efficient IM may reduce the number of nonlinear dynamic analyses that are needed to estimate the seismic demand with

CORRELATING GROUND MOTION INTENSITY MEASURES WITH STRUCTURAL ACCELERATIONS
Non-structural components (NSCs) are elements within the building that are unrelated to the lateral load-carrying system. The failure of NSCs during earthquakes can result in casualties, significant economic losses, disabled critical infrastructures, and loss of building functionality.openaire +1 more source
Evaluation of Ground-Motion Intensity Measures for Seismic Response of Fault-Crossing Tunnels
Tunnelling and Underground Space TechnologySeismic damage mechanisms of fault-crossing tunnels are complex and involve the coupled effects of fault offset and seismic ground motion. Accurately characterizing seismic demand for such tunnels remains challenging due to the limitations of conventional ground-motion intensity measures.

Seismic Demand Uncertainty provided by Ground Motion Intensity Measure
2012The seismic demand generated by Nonlinear Dynamic Analyses is obtained by using ground motion records having different intensities. The uncertainty and the variability of the seismic demand are highly dependent on the variable adopted as intensity measure (IM).

Ground motion intensity measures for seismic probabilistic risk analysis
Indicateurs de nocivité pour l'analyse probabiliste du risque sismique Une question fondamentale qui surgit dans le cadre de l’analyse probabiliste du risque sismique est le choix des indicateurs de nocivité des signaux sismiques. En plus de réduire la variabilité de la réponse structurelle (ou non structurelle),un indicateur amélioré ...openaire +1 more source
