The performance of nonstructural building components in
the January 17, 1994 Northridge earthquake has received
a considerable attention, especially building mechanical
systems. There has been much anecdotal information
indicating less than satisfactory system integrity
during and following the Northridge earthquake, which
measured 6.8 on the Richter scale. fire sprinkler
systems are of special interest since they are expected
to remain functional following earthquakes so as to
address post-earthquake fire hazards, and because of the
potential for significant water damage that can take
place if the system is compromised in a building which
otherwise remains structurally intact. This project was
recommended to include two parts:  An analysis of
the performance of fire sprinkler systems in the
Northridge earthquake in relation to the specific
earthquake protection measures employed in their design
and construction, and  Development of proposed
changes to the national installation standard, NFPA 13,
which would improve future system performance by
bringing brace fastener detials and other aspects of the
protection rules up to current levels of technology.
