Abstract
![CDATA[Composite steel-concrete beams are increasingly becoming the most widely used method of construction for steel framed bridges, buildings and stadia. Some existing composite structures may not satisfy current load requirements and require retrofitting or strengthening to extend the design life and reduce the costs on 'new build'. Recent studies showed that the blind bolts could be utilised to retrofit/strengthen existing composite structures. Monitoring and evaluation of the efficacy of the retrofitting/strengthening strategies using blind bolts is a key aspect of structural health monitoring. In this paper, two types of damage indicators are presented to assess the condition of shear connection system, and then the laboratory testing has been carried out to study the behaviour of composite beams retrofitted with different shear connection systems. Three full-scale composite beams retrofitted with different shear connection systems have been tested in laboratory and the results are compared with that from original design beams. During the tests, the dynamic behaviour of beams are monitored using impact tests. The relationship between the condition of composite beams and modal parameters has been obtained.]]
