This paper presents an approach for the rapid seismic loss assessment of infrastructure systems, where all probabilistic variables are modeled through a Bayesian Network (BN). While BN-based approaches have been introduced as promising tools for the risk assessment of systems, they suffer from computational issues (i.e., combinatorial explosion) that prevent their application to large real-world networks that require accurate and

This paper will explain the elementary aspects related to structural robustness. The concept of structural integrity is firstly introduced and next it is considered how it varies in time. The different kind of progressive collapses are introduced with reference to real cases. Design strategies are then explained with reference of bridges and viaducts, considering examples. Finally, considerations about a more general view of structural robustness are enlightened. The role of design clima and conceptual design is stressed also in connection with structural health monitoring.
