Resumo

Bridges are essential elements of transportation networks due to their strategic role and their vulnerability to natural and man-made hazards, particularly earthquakes, which can lead to partial or total service interruptions. This study proposes an improved model for assessing the seismic reliability of reinforced concrete bridges before a seismic event to enhance their resilience and improve disaster preparedness. In the first step, factors influencing reliability were identified based on a literature review and expert opinions. Next, the Analytical Hierarchy Process (AHP) was used to determine the relative weight of each factor, and a Seismic Reliability Index (RSI) was calculated by combining these weights with bridge-specific data. The model proposes three levels of reliability: low, medium, and high. It was applied to several bridges located in seismic zones in Algeria. Finally, this study presents and discusses the main results obtained, highlighting their usefulness for decision-makers in infrastructure resilience improvement strategies.
