More detailed documentation has been presented in an NIST Special Publication, , " Northridge Earthquake: Performance of Structures, Lifelines, and Fire Protection Systems. " 1. INTRODUCTION A strong earthquake of magnitude centered under the community of Northridge in the San Fernando Valley in California shook the entire Los Angles. In general, inadequate bracing was cited as a major factor in the most significant failures of fire sprinkler systems during the Northridge (Fleming ) and the Kobe, Japan, earthquake. Also, failure of unbraced small diameter piping (less than 1-in. diameter) and interaction between the sprinkler head and the ceiling, which resulted in failure of the head, were also common in the Northridge earthquake.
Also, according to the non-profit Home Fire Sprinkler Coalition, the average fire loss in a house with a sprinkler system is $2, as opposed to $45, in a home without the protection. Sprinkler systems reduce fire damage by up to 97 percent (Source). SPRINKLER SYSTEM PERFORMANCE BY THE NUMBERS. A review of historical sprinkler system statistics reveals common failure modes of sprinkler systems. The National Fire Protection Association (NFPA) publishes data summarizing sprinkler system performance in the United States on a .
Northridge earthquake , etc.) being not covered by any design code. Fire design codes make the assumption that at the beginning of the fire event, the structure is still in the elastic region of material behaviour, and that all the measures for fireproofing are active (fire coatings, paints, sprinkler systems. was shut down for many weeks due to failure of fire sprinkler piping system during the Northridge earthquake (Ayres and Phillips, ). Many researchers have recognized the importance of nonstructural components in the critical facilities. Therefore, many attempts were .

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, N which would improve future system performance by bringing brace fastener detials Cited by: ANALYSIS OF FIRE SPRINKLER SYSTEM PERFORMANCE IN THE NORTHRIDGE EARTHQUAKE Prepared for U.S.

Analysis of Fire Sprinkler Systems Performance in the the Northridge earthquake and comparison with the seismic design standard Three system-level damage states were defined based on the. An automatic fire sprinkler system is a key non-structural element which can have major impacts on both the fire safety and building functionality if damaged during a seismic event.

In: Beall KA (ed) U.S./Japan government cooperative program on natural resources (UJNR). An in-depth study of the performance of fire sprinkler systems during the Northridge earthquake influenced many of the standards (Analysis of Fire Sprinkler System Performance in the Northridge Earthquake, Russell Fleming, NFPA, National Institute of Standards Publication NIST-GCR).
Xu et al. proposed a seismic damage assessment method based on a building information model (BIM) of the sprinkler system, which can efficiently and accurately determine its overall fire.
Section allows the use of alternative methods of providing earthquake protection of sprinkler systems based on a seismic analysis certified by a registered professional engineer such that system performance will be at least equal to that of the building structure under expected seismic forces.
There has been some research conducted into the integrity of sprinkler systems following earthquakes, such as the Northridge event on Janu in California (Fleming ; Todd et al. ), the Janu Kobe, Japan earthquake (Sekizawa et al. ), and the Canterbury earthquakes in New Zealand in and (Houston and Mak ), although.

Beijing: China Architecture and Building Press, (in Chinese). sprinkler system is known for fires of these cases.
Across all fires for which data were available, the sprinkler systems contained or controlled the fires in 62% of incidents and extinguished the fire in 37% of incidents. Hence, the performance effectiveness of sprinkler systems. Fire sprinkler systems have been assigned an Ip of (ASCE ) because they are considered life safety systems.
Therefore, this exemption cannot be applied. The fifth and sixth exemptions, while applying to mechanical and electrical components, both include a requirement for an Ip equalingmeaning fire sprinklers are not allowed.
Unfortunately, the seismic performance of existed hospital sprinkler systems in Taiwan was unsatisfactory. From the literature review of earthquake damages, the reduction of medical functionality has been caused by serious flooding due to broken sprinkler.
Sprinklers were present in only 10% of reported structure fires in Most structure fires and fire deaths occurred in homes, but sprinklers were found in only 7% of all home fires.
Sprinklers were most likely to be found in institutional occupancies such as nursing homes, hospitals, and prisons or jails. Sprinkler Systems in Earthquakes •NFPA 13 includes provisions for minimizing damage to sprinkler systems during earthquakes •Provisions are regularly revised based on experience and knowledge •Extensive modifications occurred after San Francisco earthquake ofthe Loma Prieta Earthquake of and the Northridge earthquake in and Northridge hospital in the San Fernando Valley during the Northridge earthquake (FEMA P, ).
According to a literature review on earthquake damage (Huang, ), the common damage states of sprinkler piping systems include screwed fittings, broken anchorages, and sprinkler heads. One such situation was observed at a. Through a partnership with HFSC, the Maryland State Fire Marshal's Office, the Prince George's County (MD) Fire Department, and the University of Maryland University College, this study reviews Prince George's County's experience with an ordinance mandating the installation of automatic fire sprinkler systems in new one- and two-family.

Although effective fire sprinkler systems are crucial to public safety, for years, the designers of those systems had few published resources to reference and guide them through their design processes. The first edition of this book changed all that, and now The Design and Layout of Fire Sprinkler Systems Second Edition suits their needs even bette.Fire Sprinkler Systems Technical Paper Febru Martin King.
Fire sprinkler systems can be found in a wide range of buildings or structures from warehouses to multi-story buildings, ships, oil rigs etc. Sprinkler systems are used to provide a reliable method of automatically detecting and extinguishing fires at an early stage.The impact of damage to fire protection NCS has been observed in numerous earthquakes, including the Northridge and Kobe earthquakes, where damage to fire sprinkler systems and fire doors was reported to be over 40% and 30% respectively.
