Abstract
![CDATA[Of the nearly 5000 bridges in New South Wales, about 17% are more than 50 years old. Most of these older bridges are considered structurally deficient by modern standards for the loads they are required to carry. These bridges will have to be replaced or strengthened by utilizing post installed shear connection systems. In this project two types of blind bolt connectors are being used as shear connection systems in steel-concrete composite beams alongside a welded shear stud system, and a non composite beam for comparison. The use of high strength non shrink grout in retrofitting procedures for shear connections can lead to differences in modal parameters of beam specimens to varying degrees at different levels of induced damage. This phenomenon has an effect on the way in which changes in modal parameters are interpreted in structural health monitoring systems. An experimental series is presented with two specimens for each type of shear connector. The first set is cast in whilst the second set is retrofitted. Each of the specimens is tested in intervals to destruction and the result compared.]]
