dc.description.abstractReinforced concrete decks submerged in water suffer from considerable deterioration owing to high cycle repetition of traffic loads with increasing rise of inter-crack water pressure, which leads to serious damages to the top surface of concrete decks due to dropping (disintegration) of cement binder. In this study, an attempt was made to incorporate the disintegration of concrete composites into a three-dimensional multi-scale finite element analysis, which is capable of tracing the path from the occurrence of cracking to the structural out-of-plane shear failure via crack propagation. Varying fatigue life is also discussed in accordance with different states of damage at the time when strengthening work is performed. Here, the deck strengthening methods of wide variety are compared with each other.
