Integrating MCDM to enhance bridge resilience

Natural hazards occurrences show dynamism in terms of its frequency and severity. While infrastructure, like bridges, account for normal forces of natural hazards, dynamism results in negating assumptions of severity and frequency. The incremental forces influence structures, triggering an exponential deterioration process.

The research explores possible approach to enhance resilience in bridges. It defines the boundaries for the bridge geometry and distress levels that will need to be adhered for ensuring survival of the bridge. The research identified four criteria namely Structural status of bridge structure, Risk assessment for natural hazards, Financial due diligence, and Socio-Economic impact of the bridge on the region. Multi-Criteria Decision Making (MCDM) integration holds the key to enhance resilience of bridges.
