Cost- And Resilience-Based Prioritization of Bridges for Pre-Earthquake Strengthening

This webinar presents an innovative framework for the prioritization of bridges for seismic retrofitting, combining economic cost metrics with a resilience-based decision-making approach.

Key contributions include:

• A resilience index that accounts for socioeconomic impacts, such as downtime and indirect losses.
• A multi-criteria prioritization strategy for pre-earthquake strengthening interventions.
• Application to real-world scenarios, demonstrating optimal resource allocation among bridge assets.

The methodology extends prior post-disaster optimization models, with a shift toward proactive, pre-event planning.

Organized as part of the RCS Webinar Series with international reach in the field of earthquake resilience and infrastructure systems.
