Abstract
This paper deals with the high-strength bolted friction-slip joints using the carbon steel flat bar with the slotted hole. To clarify the slip load, the dynamic hysteresis characteristics and the permissible region for the scuffing, the dynamic tests under the constant-amplitude displacement-cycling were conducted. The test parameters are the location of the slotted hole, the slip velocity, the bolt clamping force and the steel grade. The results indicate that the energy absorption capacity of the joints where the outer plates have the slotted hole is larger than that of the joints where the inner plate has the slotted hole, the hysteresis loop is the rigid-plastic type and the cumulative slip deformation of the cold-finished carbon steel flat bar is significantly affected by the bolt clamping force and the slip velocity.
