A key component of the NGA research project was the development of a strong-motion
database with improved quality and content that could be used for ground-motion research …

A simplified semiempirical predictive relationship for estimating permanent displacements
due to earthquake-induced deviatoric deformations is presented. It utilizes a nonlinear fully …

The objective of performance-based earthquake engineering (PBEE) is the analysis of
performance objectives with a specified annual probability of exceedance. Increasingly …

Earthquakes are nearly unique among natural phenomena-they affect virtually everything
within a region, from massive buildings and bridges, down to the furnishings within a home …

Arias Intensity is a ground motion parameter that captures the potential destructiveness of an
earthquake as the integral of the square of the acceleration–time history. It correlates well …

A global dataset of more than 3,000 ground motion records from 536 sites from Greece, Italy,
Turkey, USA and Japan is compiled and used to propose code-oriented elastic acceleration …

The frequency content of an earthquake ground motion is important because it affects the
dynamic response of earth and structural systems. Four scalar parameters that characterize …

We develop empirical relationships to predict nonlinear (ie, amplitude-dependant)
amplification factors for 5% damped response spectral acceleration as a continuous function …

In this paper the site categorization criteria and the corresponding site amplification factors
proposed in the 2021 draft of Part 1 of Eurocode 8 (2021-draft, CEN/TC250/SC8 Working …

Earthquake is a sudden release of energy due to faults. Natural calamities like earthquakes
can neither be predicted nor prevented. However, the severity of the damages can be …
