This paper reports on the hysteretic behaviour of Asymmetrical Friction Connection (AFC) assembled with different shim materials such as Aluminium, Brass, Mild Steel, Bisalloy 80, Bisalloy 400, and Bisalloy 500 subjected to a cyclic displacement regime applied with a quasi-static velocity of 10 mm/s and with higher velocities of 190mm/s. Results show that at the high velocity regardless of the shim material the hysteresis loop is less stable, and greater forces are required to activate the sliding mechanism of the slotted plate when compared with the hysteresis loop at the low velocity. Boundaries of the effective friction coefficient for the quasi-static and high velocity cases, as well as a model that represents the velocity dependence of AFCs in terms of the effective friction coefficient are presented.
