Bolt shear connectors have the advantage of efficient installation and demolition when used in prefabricated composite beams. When bolt shear connectors are damaged in the service period and replaced by new ones, the sheer performance of the replaced bolts will be affected by the existing structural damage. This paper experimentally investigates the shear performance of eleven re- assembled push-out specimens of bolt connectors. The experimental results show that the replaced bolts possess a similar shear resistance as the bolts in the original tests. In contrast, the relative slips at the interfaces between the steel beam and the prefabricated concrete (PC) slabs show a bigger scattering. A calculation method of shear resistance for the replaced bolts considering the influence of the existing damage was proposed based on the experiments, and comparisons show that the calculation values agree well with the experimental results. |
