Performance Based Earthquake-Resistant Design: Migrating Towards Nonlinear Models and Probabilistic Framework

Abstract

In this work we present our recent works that follow two modern tendencies in modelling and design of engineering structures for extreme loading such as earthquakes: (i) fine scale models for providing the simplest, fine-scale interpretation of inelastic damage mechanisms at the origin of energy dissipation and damping phenomena, as opposed to coarse scale of stress resultants; (ii) the role of probability in this kind of modelling approach. We consider application of these ideas first to structures, especially irreplaceable structures, such as nuclear power plants, and move onto the complex systems such as water networks. Keywords
