Estimating Arias Intensity From Response Spectrum

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Arias intensity serves as a crucial metric to measure ground motion energy and is extensively utilized in earthquake engineering to analyze structural damage, slope instability, and the potential for soil liquefaction. Nevertheless, in many practical design scenarios, only the response spectrum is available, without corresponding information ...

The flow liquefaction phenomenon. Theoretical and practical approach

Geotecnia, 2022
In recent years and due to the increase in mining activity, the number of events that have brought catastrophic and sudden ruptures in the mine waste deposits, with the loss of numerous human lives, has increased. In many cases, the main cause of these failures has been interpreted as flow liquefaction.
