TL;DR: A novel framework for the quantitative resilience assessment of critical infrastructure, subjected to multiple hazards is proposed, considering the vulnerability of the assets to hazard actions and the rapidity of the damage recovery, including the temporal variability of the hazards.

TL;DR: In this paper, the authors proposed a methodology for assessing the seismic risk of structural systems equipped with linear and nonlinear viscous damping devices while accounting for the uncertainties affecting both seismic input and model parameters.

TL;DR: In this paper, the authors provide an up-to-date, comprehensive, and holistic literature review of the problem of scour at bridge foundations, with a focus on the following topics: sediment particle motion, physical modelling and controlling dimensionless scour parameters; scour estimates encompassing empirical models, numerical frameworks, data-driven methods, and non-deterministic approaches; current approach for assessment and design of bridges against scour; and, research needs and future avenues.

TL;DR: In this article, the influence of friction pendulum system (FPS) isolator properties on the seismic performance of base-isolated building frames is analyzed by employing a two-degree-of-freedom model accounting for the superstructure flexibility, whereas the FPS isolator behavior is described by adopting a widespread model that considers the variation of the friction coefficient with the velocity.

TL;DR: In this article, the authors proposed a probabilistic performance-based procedure for assessing the mean annual frequency of pounding between adjacent buildings, under the assumptions of linear elastic behavior for the buildings and of non-stationary Gaussian input ground motion.
