Facebook Intensity Measure

Communication Research Measures III, 2019
The Facebook Intensity Measure was developed by N. B. Ellison, C. Steinfield, and C. Lampe as a scale that measures how individuals use Facebook and how emotionally connected to the platform they feel. Facebook intensity has been studied in the contexts of social capital and students’ transition to college, college student trust and political ...

Effect of near-fault directivity pulses on ground-motion intensity measure correlations from the NGA-West2 data set

Earthquake spectra, 2023
This article investigates the correlation coefficients of ground-motion intensity measures for ground motions containing near-fault directivity velocity pulses.

Ranking of ground motions destructive capacity for low- and middle-rise RC frame structures based on a comprehensive intensity measure

Advances in Structural Engineering, 2022
To quantitatively evaluate the destructive capacity of ground motions for Chinese seismic design, a method to rank the ground motion based on a new comprehensive intensity measure is proposed.

Evaluation of intensity measure performance in regional seismic risk assessment of reinforced concrete bridge inventories

Structure and Infrastructure Engineering, 2021
Seismic risk assessment requires fragility functions derived using non-linear time-history analysis with earthquake records compatible with the site hazard and characterised via a suitable intensity measure (IM), which poses a challenge given the wide ...

Ground-Motion Intensity Measure Correlations on Interface and Intraslab Subduction Zone Earthquakes Using the NGA-Sub Database

Bulletin of The Seismological Society of America (BSSA), 2021
The NGA-Sub (subduction zone earthquake) database developed by the Pacific Earthquake Engineering Research center is used to derive new correlation coefficients for a number of ground-motion intensity measure (IM) parameters from ground motions in ...

A vector‐valued intensity measure for near‐fault ground motions

Earthquake engineering & structural dynamics (Print), 2020
Near‐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)

Multi‐criteria decision making for seismic intensity measure selection considering uncertainty

Earthquake engineering & structural dynamics (Print), 2020
Seismic intensity measure (IM) selection is associated with consideration of multiple criteria, and there are uncertainties within the selection process.

Entropy‐based intensity measure selection for site‐specific probabilistic seismic risk assessment

Earthquake engineering & structural dynamics (Print), 2020
Intensity measure (IM) selection is a critical step in probabilistic seismic risk assessment (PSRA). In many past studies, the efficiency of an IM, which quantifies its explanatory power within a probabilistic seismic demand model, has been a predominant
