Abstract EN
The increasing traffic demand is continuously growing worldwide.
Therefore, the life of a large stock of bridges that still exist throughout the world must be extended, ensuring at the same time that safety is not compromised for economic reason.
This paper introduces the possibility to control the fatigue life of existing bridges by using a vibration control system.
Based on a dynamic optimization analysis, the stresses from traffic on the bridge are obtained.
Subsequently, a plate finite element (FE) model of the whole bridge is developed.
The equation of motion is presented for a case study bridge, equipped with different tuned mass damper system, and the combination of external loads and train/track interaction with or without the TMD system is developed through own-developed routines and FEM software.
The procedure is showcased for a case study bridge.
After gaining the stress states at the critical hotspot, the fatigue crack life is evaluated by using the linear cumulative damage theory.
The different TMD solution presented is demonstrated to be able to diminish the stress level in critical hotspots, improving the overall fatigue life of the bridge over an established lifetime.
