Ground Motion Intensity Measures
2021Ground motion is the movement of the earth’s surface from earthquakes or explosions. The earthquake ground motion is produced by waves that are generated by a sudden slip on a fault and travel through the earth and along its surface. Typical the ground motion records, such as acceleration time histories, contain a tremendous amount of information.

Information-Based Relative Sufficiency of Some Ground Motion Intensity Measures
, 2012 The seismic risk assessment of a structure in performance-based design (PBD) may be significantly affected by the representation of ground motion uncertainty. In PBD, the uncertainty in the ground motion is often represented by a probabilistic description of a scalar parameter, or low-dimensional vector of parameters, known as the intensity measure (IM)

Ground Motion Intensity Measures for Liquefaction Hazard Evaluation
Earthquake Spectra, 2006The requirements of performance‐based earthquake engineering place increasing importance on the optimal characterization of earthquake ground motions. With respect to liquefaction hazard evaluation, ground motions have historically been characterized by a combination of peak acceleration and earthquake magnitude, and more recently ...

Ground Motion Intensity Measures for Rocking Building Systems
Earthquake Spectra, 2017This paper investigates the effectiveness of various ground motion intensity measures (IMs) in estimating the structural response of two types of rocking systems: (a) a controlled rocking steel braced frame system with self‐centering action and (b) a rocking spine system for reinforced concrete infill frames.

Evaluation of Intensity Measures for Pulse-Like Ground Motions
Advanced Materials Research, 2010The correlation between intensity measures (IM) for pulse-like ground motions and nonlinear deformation demand of single-degree-freedom-systems (SDOF) is researched, and the efficiency of IM is described. Based on dynamic time analysis of SDOF systems subjected to 72 pulse-like ground motions, the present study investigates the variation of the ...

A vector‐valued intensity measure for near‐fault ground motions
Earthquake Engineering & Structural Dynamics, 2020SummaryNear‐fault ground motions containing high energy and large amplitude velocity pulses may cause severe damage to structures. The most widely used intensity measure (IM) is the elastic spectral acceleration at the fundamental period of the structure (Sa(T1)); however, Sa(T1) is not a sufficient IM with respect to the effects of the pulse‐like ...

An index for measuring the effects of topography on seismic ground motion intensity
Earthquake Engineering & Structural Dynamics, 1986AbstractAn index is proposed for the quantitative evaluation of topographical effects, as may be required in seismic microzoning and structural design applications. This topographical effects index (TEI) is defined as the relative Arias intensity for a given position.As an example, the TEI is calculated for a semicircular canyon excited by an ...

Ground Motion Intensity Versus Ground Motion Kinematics. Exploring Various Intensity Measures
2018The interest for this topic was raised by the occurrence of the destructive Vrancea earthquake of 1977.03.04, when the first strong motion record of Romania was obtained at the Building Research Institute (INCERC) Bucharest. The attempt to assess the ground motion intensity on the basis of instrumental criteria specified by the Medvedev-Sponheuer ...

Correlation analysis of structural response and ground motion intensity measures
2021Estimation of losses due to earthquake-shaking induced building damage is an important step in Performance Based Earthquake Engineering (PBEE). The implementation of PBEE depends on the ability to predict Engineering Demand Parameters (EDPs) from ground motion Intensity Measures (IMs).
