Fatigue experimental characterization of preloaded injection bolts in a metallic bridge strengthening scenario

All over the world, the number of civil engineering structures, particularly bridges with long service periods, has been increasing. The most common evidences of damages are the presence of corroded metallic elements and cracks in structural details due to the fatigue phenomenon. A large number of cases were found in which fatigue cracks were...

Reliability of Fatigue Strength Curves for Riveted Connections Using Normal and Weibull Distribution Functions

In North America and Europe, there is a significant number of centenary metallic bridges that require maintenance and strengthening operations. These structures need to be adapted to increasing traffic intensities, and their structural integrity should be constantly evaluated. Fatigue damages were not considered in the original design of old...
