Simulation Analysis of Scour Impacts on the Dynamic Properties of A Bridge Structure

摘要

Many damages of bridge are caused by scour. This paper tries to find out the relationship between the changes of dynamic properties of bridges and scour. The influence of scour on the Mississippi State Highway 33 Bridge is analyzed considering 2 factors, the scour depth and the water level. A Finite Element model is used to simulate the vibration of the bridge under scour. The results reveal the effects of scour on the dynamic properties of the bridge.
