Probabilistic seismic hazard analysis using a new ground motion intensity measure [PDF]

Dyna, 2016
The main objective of this work is to compute the probabilistic seismic hazard analysis for a region of Mexico using a new ground motion intensity measure which is based on the spectral acceleration and a parameter proxy of the spectral shape named Np ...

An energy-frequency parameter for earthquake ground motion intensity measure [PDF]

Earthquake Engineering & Structural Dynamics, 2022
A novel scalar ground motion intensity measure (IM), termed the energy-frequency parameter, is proposed based on the Hilbert-Huang transform. To validate the effectiveness of the proposed IM, the correlation analysis between the engineering demand parameter (EDP) and energy-frequency parameter is performed using 1992 recorded ground motions, in which ...

Ground-Motion Intensity Measures for the Seismic Response of the Roof-Isolated Large-Span Structure

Buildings
Ground-motion intensity measures (IMs), which quantify and describe the characteristics of earthquake ground motion, are of utmost importance in the assessment of seismic risk and the design of resilient structures with large spans.

Selection of Ground Motion Intensity Measure for Reinforced Concrete Structure [PDF]

Procedia Engineering, 2015
AbstractThis paper presents analysis of different ground motion intensity measures that can be used in assessing the behavior of reinforced concrete structures. For this analysis, eight-story reinforced concrete building is selected with frame structural system in one direction and wall system in the other direction. The nonlinear time-history analysis

Support Vector Machines to Propose a Ground Motion Prediction Equation for the Particular Case of the Bojorquez Intensity Measure I_Np

AI
This study proposes the first ground motion prediction equation (GMPE) for the parameter INp, an intensity measure based on the spectral shape. A Machine Learning Algorithm based on Support Vector Machines (SVMs) was employed due to its robustness ...

Time evolution of ground motion-dependent depolarisation at linear colliders [PDF]

, 2009
Future linear colliders plan to collide polarised beams and the planned physics reach requires knowledge of the state of polarisation as precisely as possible. The polarised beams can undergo depolarisation due to various mechanisms. In order to quantify

Ground-motion intensity measure correlations observed in Italian strong-motion records [PDF]

Earthquake Engineering & Structural Dynamics, 2019
SummaryGround‐motion models (GMMs) are widely used in probabilistic seismic hazard analysis (PSHA) to estimate the probability distributions of earthquake‐induced ground‐motion intensity measures (IMs) at a site, given an earthquake of a certain magnitude occurring at a nearby location.

Selection of Ground Motion Intensity Measures in Fragility Analysis of a Mega-Scale Steel Frame Structure at Separate Limit States: A Case Study

Buildings, 2022
Selecting an appropriate ground motion intensity measure (IM) to estimate the aleatory uncertainty produced by ground motion variability is the first and crucial step in fragility analysis. The choice of IM is influenced not only by the structural system

Comparison of real and simulated records using ground motion intensity measures

Soil Dynamics and Earthquake Engineering, 2021
Abstract Simulated ground motion records have recently become major alternatives to real records. In this study, differences between simulated and real record sets are evaluated in terms of alternative ground motion intensity measures. As case studies, two regions in Turkey (Erzincan and Duzce) are considered.
