• Abstract:
  This study is to develop simulation methodology to conduct the dynamic assessment of bridge deck performance subjected to traffic. Concrete bridge decks are exposed to daily traffic loads and may experience some surface cracking caused by excessive stress or fatigue accumulation. Bridge decks experiencing such cracking will require repair or replacement. In the present study, a hybrid dynamic analytical approach is developed for a typical multi-span concrete bridge and stochastic traffic flow by considering the excitation from road roughness. Based on the dynamic response results, the fatigue assessment is also conducted focusing on providing some insights on vulnerable locations and the impacts from different traffic, and road roughness conditions.
