| Popis: | Most of engineering infrastructure including bridges impacts significantly civilians life quality and safety. Despite carrying their own weight and live load during operation, structure members are also seriously affected by disaster and environment. This research paper proposed an investigation in the changes of vibration frequency and the main girder(road) deflection. The outcome of the dynamic analysis that considered a vehicle traveling on the bridge, demonstrate that the vibration characteristics and the deflection response changed as damage progressed. It was discovered to be possible to identify the conditions leading to advanced deformations and collapse of the bridge. The paper finally proposes an sensor network able to identify the earliest damage which can occurs on the bridge. |
