In response to the innumerable reports of fire-damage from seismic disasters, various sorts of preventative measures have been implemented. And while sprinkler systems are practically standard as automated facilities, in earthquakes the possible leakage or damage to the piping from the primary disaster can nullify the system's fire-extinguishing function, thus rendering it totally worthless. Further, the water gushing from broken pipes can damage other components, including electrical systems. Thus ensuring the sound strength of the piping structure for such disaster mitigating systems as sprinklers is imperative. Using a high-rise office-building as an example, this report analyzes the strengths of sprinkler system for an entire floor and the components of its piping-structure, looking into how they show different strengths according to the scale of the earthquake, the direction of the vibration, and the conditions of the pip-supporting.
