Strength Evaluation and Retrofitting of Deteriorated Corrugated Girder
Girders are horizontal structural supports that carry greater loads and are responsible for load transfer over longer spans. A structurally deficient girder may lead to the complete failure of structure. Corrosion is one of the major reasons for deterioration of the girder strength. Replacement of such girders is not possible and hence alternate strengthening methods have to be proposed. In this paper, performance degradation of corrugated steel girder in shear buckling under various damage scenarios have been discussed. An attempt has been made to analyse the strength of corrugated girder by imparting corrosion in three forms of surface corrosion. Also, the effect of retrofitting methods using fibre reinforced polymers (FRPs) on the strength of damaged corrugated girders has been studied using nonlinear static analysis in ANSYS Workbench 2021 R2 Software. The results indicate that the thickness loss governs the failure of steel girder and corrugation helps in better corrosion resistance. Also, it was found that the strength of the deteriorated girder could be enhanced by retrofit using carbon fibre reinforced polymer.
