Abstract
The slip behavior and failure properties of perfobond rib shear connector (PBL) were investigated by various loading tests. Static push-out tests were conducted under several different restraint conditions to examine the influence of restraint conditions on the shear force-slip relation. Observation of cracked surface in perforation after the loading tests indicated that the reversal cyclic tests accelerated smoothing of rough crack surface. The fatigue lives obtained from identical loading condition were scattered in 10000 times different. The fatigue limit diagram of the PBL was formed based on both the past and our experimental results. The observation of cracked surface in perforation after the loading indicated that the concrete dowel can be broken along two crack plains, even if thickness of PBL is 6.5mm thin.
