Fatigue estimation for critical structures necessitates comprehensive monitoring, which, in turn, requires dense instrumentation and models that heavily rely on computational resource. However, the fatigue vulnerability of different segments within infrastructure can be considered to adopt a cost-effective substructure-based monitoring approach, minimizing need extensive or complex models. estimating instrumenting substructure boundary adds complexity. In addition, conventional approaches often assume constant structural health, disregarding unknown current health status aging structures. To overcome this limitation, novel life approach is developed, incorporating an interacting ensemble-particle filter considers while remaining robust against forces. Numerical experiments validate proposed simulated reinforced concrete box girder bridge, utilizing 3D beam model accounts dynamic interaction with vehicles. A parametric analysis investigates relationships between damage factors such as surface roughness, vehicle speed, weight, category, aiming identify dominant stimuli. The results demonstrate accurate parameters useful (RUL). Furthermore, decomposed RUL enabling mapping traffic information without requiring costly simulations. case study highlights practical applicability focusing bridge Himachal Pradesh, India.
