Risk assessment of bridges and road networks subjected to natural hazards - Minisymposium 37 - all'interno della conferenza internazionale COMPDYN 2021 28-30 June 2021, Streamed from Athens, Greece - 8th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering.

Safety of bridges and road networks is of paramount importance since their disruption might have high socio-economic impact as well their collapse could seriously endanger people life. For this reason, it is important to assess the vulnerability of this type of infrastructures against various sources of hazards: flood-induced scour, landslides, wind, hurricanes, earthquakes. Moreover, the effect of ageing, poor maintenance, lack of knowledge and outdated design criteria (i.e. not-updated traffic loads or non-seismic design) make these systems among the most vulnerable elements of the network infrastructure. An accurate capacity assessment of existing bridges is thus extremely important for characterizing the main structural deficiencies, estimating the risk and prioritizing retrofit interventions to improve the system resilience. Based on these premises, this Special Session offers the opportunity to present and discuss the last researches on this wide topic, and contributions addressing experimental, computational, and methodological developments are welcome, as well as proposals of: - numerical and predictive models suitable for bridge risk assessment; - new techniques of monitoring and testing; - multi-hazard risk assessment and probabilistic analysis; - innovative techniques for seismic isolation or energy dissipation for bridges; - applications and case studies
