Prediction of time of liquefaction using kinetic and strain energy
TLDR
In this article, the authors developed a theoretical framework and simple procedure to predict the build-up of excess pore pressure based on the principles of conservation of energy, which is shown through the evaluation of experimental cyclic simple shear tests to be insensitive to loading amplitude.About:

Cyclic and Dynamic Behavior of Sand–Rubber and Clay–Rubber Mixtures
TL;DR: In this article, the possibility of using fine scrap tyre rubber to improve the mechanical properties of soil subjected to cyclic loading is addressed, and the results have shown that the addition of rubber has significantly decreased the density and shear stiffness of both types of soils, which favours mitigation of vibrations.

Seismic intensity measures for risk assessment of bridges
TL;DR: In this article, the authors examined the efficient assessment of simple bridge structures characteristic of the European context by exploring different seismic intensity measures based on Sa(T), peak ground velocity (PGV) or a recent candidate average spectral acceleration, AvgSa.

Liquefaction and post-liquefaction of granular material under multi-directional cyclic loading
TL;DR: In this paper, the authors investigated the liquefaction behavior of granular material under complex loading co-efficients and magnitudes, and showed that granular liquidation can be induced by natural events that entail complicated loading directions and magnitude.

Physics-Informed Probabilistic Models for Peak Pore Pressure and Shear Strain in Layered, Liquefiable Deposits
TL;DR: In this paper, the authors developed probabilistic models for estimating the peak excess pore pressure ratio (ru) and peak shear strain (γmax), which control liquefaction triggering, in layered granular soils under earthquake loading.

Time–Frequency Filter for Computation of Surface Acceleration for Liquefiable Sites: Equivalent Linear Stockwell Analysis Method
TL;DR: In this paper, the authors present a method for performing equivalent linear analysis that allows for a variation of the stiffness and equivalent viscous damping properties throughout the duration of the analysis, allowing for a different stiffness and damping property throughout the analysis.

Conditional Mean Spectrum: Tool for Ground-Motion Selection
TL;DR: In this paper, the authors proposed the use of the conditional mean spectrum (CMS) as the appropriate target response spectrum for ground motion selection in dynamic structural analysis, which is a useful tool for selecting ground motions as input to dynamic analysis.

Yielding of Clays in States Wetter than Critical
TL;DR: In this article, a new energy equation is proposed, well supported by experimental evidence, from which a stress-strain relationship is developed for virgin and lightly overconsolidated clays.
