Transient Structural health monitoring of The Test Bridges Using Finite Element Method

Failure of the bridges is the biggest threat to human life as well as the assets. To avoid the structural failure, Transient Structural Health Monitoring (SHM) of bridges could be carried out during its service life, in order to meet the service, safety and reliability requirements. Hence in this research, transient structural analysis (SHM) using Finite Element Method (FEM) is conducted of intact as well as damaged test bridge that are having the same physical parameters to analyze non-linear behavior change of the damage that is generated in the test bridge, when some loading conditions are applied using FEM. The authenticity of this analysis can be clearly shown, when the transient structural parameters are been compared between the two test bridges. Variations in the parameters like equivalent stresses, principle stresses, deformation and maximum equivalent strain are analyzed for the structural condition monitoring of the test bridges. These two test bridges, represents the actual bridges that are being used in day to day lives. So, in real case scenario, like these two test bridges, the simulation of the actual bridges can be conducted by comparing the actual bridge models.
