  • Description: Bridges are an important part of the traffic infrastructure, which are subjected to high safety requirements and economic consequences in case of functionality failure. Therefore, it is needed to consider potentially substantial direct and indirect risks during service life, i.e., the need for risk and robustness analyses. Over the last decades, various quantitative performance criteria have been developed but their interrelation and compatibility has hardly been systematically studied. This paper contains a proposal of a novel and complementary formulation of interrelations between reliability- and risk-based robustness, importance, and redundancy indicators. The classification, derivation, and exemplification of the interrelations between these indicators are presented and formulated for two case studies of a pre-stressed concrete bridge considering different hazard scenarios namely overloading and chloride attack. The analyses and applications lead to the identification of interrelations between the reliability based robustness, redundancy and importance indicator indicators and with the risk based robustness indicator.
