Friction springs are carving out a growing niche in the seismic protection applications. Working as part of a sliding joint assembly, friction springs can protect buildings, power generation equipment and other infrastructure from eathquake damage.

The friction springs used in seismic applications tend to be large. Yet, they are still quite compact for the amount of energy they can absorb. For example, a spring capable of absorbing 13,400 Joules of energy measures just 198-mm across and 334-mm high when pre-loaded.

One place friction springs have become prominent is in New Zealand, which suffered a devastating earthquake in 2011. One facility had already been outfitted with friction springs prior to that quake—and the building survived unharmed. Other buildings and power generation infrastructure have since gotten friction springs of their own.
