Bridges are exposed to high seismic risks, making the assessment of their seismic resilience essential to ensure the continuity of critical infrastructure and reduce potential losses. This study aims to develop an integrated methodology for assessing bridge resilience simply and rapidly, based on the Simplified Tool for Seismic Resilience Assessment (STSRA), enabling experts and decision-makers to determine the level of resilience and prioritise interventions without undue complexity. The methodology is based on integrating the relative weights of primary and secondary criteria, including resistance capacity and recovery rate as primary criteria, and bridge condition, location, importance, and damage level as secondary criteria, using the analytic hierarchy process Method (AHP). The methodology was applied to a case study in a seismically active area, and the results were compared with previous studies, showing strong agreement. This confirms the accuracy of the methodology and its ability to assess the level of resilience while identifying the need for reinforcement measures. The study demonstrates that the proposed methodology is a practical tool for rapidly assessing bridge resilience, determining maintenance and reinforcement priorities for strategic bridges, and can be generalised to the entire national network to strengthen capacity to cope with seismic risks and ensure the sustainability of critical transport networks.
