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 their design life and reduce the costs on 'new build'. Recent studies have shown that blind bolts can 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 series of tests have been carried out in laboratory to study the effects of different shear connection systems. Each series of tests includes three full-scale composite beams with different shear connection systems and one non-composite beam as comparison. One series of tests considered the service load behaviour using dynamic tests, whilst the second series of tests considered ultimate strength tests using static testing. Both the service and strength tests revealed that headed shear studs can be replaced with blind bolting and achieve similar or improved stiffness or strength, hence rending the blind bolting suitable for both demountable and retrofitting purposes.]]
