Building content damage can cause significant economic loss in major earthquakes. This paper quantifies the contents damage to structures with similar backbone hysteresis curves, but with different unloading and reloading characteristics under both impulse and earthquake excitations scaled to the design level for Wellington. These sliding demands are expressed in terms of sliding spectra and they show that the amount of sliding depends on the shape of the hysteresis curve used. Two simple explanations are proposed and evaluated to determine which hysteresis loops would result in the greatest sliding damage. It is shown that a sudden increase in stiffness when the structure is moving at a high velocity is not the key factor. Instead, the velocity at the time of sliding initiation seems to correlate better with the calculated sliding distance.
