Study on Residual Strength of Riveted Joints Damaged by Corrosion

In this study, in order to clarify a relationship between a residual strength and a level of corrosion damage, and to investigate a mechanical behaviour of riveted joints damaged at rivet head by corrosion, experimental and analytical studies are carried out. In the experiments, are used the specimens which cut off from the demolished exiting steel bridge members. Experimental specimens of single lapped joints which are varied the corrosion levels are prepared and tensile tests are executed. In FE analysis, the corrosion levels of a rivet head and joint type which are single and double lapped joints are dealt with and parametric analyses are carried out. As the results of this study, it is found that the residual strength of the riveted joint damaged by corrosion is much decreased when a rivet head is corroded heavily in especially the case of the single lapped riveted joint.
