Abstract

Fire protection (sprinkler) piping system is an essential element for the energy supply and for the protection against the seismic-induced fire during and after an earthquake. The primary objective of this study was to understand the seismic performance of complex two-story piping system installed in a low-rise building subjected to bi-directional and three-directional earthquakes. The result of current study revealed that the displacement of the piping system in accordance with floor level was significantly different due to acceleration-sensitivity but the effect of the piping system due to the vertical direction earthquake was not significant.

화재방호계통 스프링클러 시스템의 경우 지진 발생 시 그리고 지진 발생 후에 유도되는 화재로부터 건물과 인명을 보호하고 에너지를 공급을 위한 필수 요소라 할 수 있다. 본연구의 주목적은 양방향 (x, y) 그리고 3축(x, y, z)방향의 지진의 영향을 받는 저층 건물에 설치된 복층구조 스프링클러 파이프라인의 거동과 내진성능을 평가 하고자 함이다. 결과적으로 건물의 비구조 요소인 스프링클러 파이프라인의 경우 각 층별로 다른 거동을 보이고 있으며, 또한 수직 방향의 지진의 경우 수평방향의 지진보다 파이프라인에 미치는 영향은 미미하다고 볼 수 있다.
