Damage Detection to Urban Girder Bridge Using Distributed Strain Response
Damage detection to urban highway bridge is establishing a prominent role in modern engineering. In this paper, damage localization index called the relative strain energy (RSE) based on the distributed strain response was introduced, and it is employed to validate the effectiveness in locating damage elements by using a FE model of an urban girder bridge under various degrees of damage assumption in the bridge's girder. The numerical analysis results show that the RSE index could locate damage position accurately in early damage of the structure, and they also have an excellent noise pollution resistance performance. Two random excitations were introduced into the analysis of the damage location in before and after damage occurrence, respectively. All of the results are presented in the form of table and graphs.
