Prediction of Ground Motion Intensity Measures Using an Artificial Neural Network
Pure and Applied Geophysics, 2021The present study aims at developing a prediction model for ground motion intensity measures using the artificial neural network (ANN) technique for active shallow crustal earthquakes in India. The database for the study consists of 659 ground motion records collected from 138 earthquakes recorded by various seismic networks in the study region.

The correlation between the ground motion intensity measure parameters of earthquakes
Asian Journal of Civil Engineering, 2020In performance-based seismic engineering, the choice of ground motion goes hand in hand with dynamic analysis. This paper presents the relationship between the various intensity measures (IMs) parameter of ground motions that can be used in evaluating the behavior of structures.

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).
