| Summary: | 碩士 === 國立成功大學 === 建築學系碩博士班 === 91 === Global earthquake experiences indicated that: fire suppression system takes a critical role of the post-earthquake building function in important buildings. In Taiwan, there is a growing demand of higher seismic resistant capacity of buildings after 921 earthquake, and so of the equipment in them. But due to the scarce research on the fire suppression system, there is a lack of standards in Taiwan. This thesis performed a basic study of the fire suppression system, and provided conclusions to relevant institutions.
To unearth the earthquake failure patterns of fire suppression system and to find a suitable method to improve its earthquake performance, this thesis investigated the earthquakes damage reports inside and outside Taiwan at first. A damage site survey of a parking building in Puli was performed. This building was completed but not operating yet before 921 earthquake. The damage situation of its fire system brings much valuable information. The analysis of reconnaissance reports of several earthquakes in the USA and Japan was performed next. These studies show that suspension systems are the main weak point of the whole fire system. That is, the function of the whole fire system could be improved effectively by reducing the relative movement of the suspension system alone.
This thesis studies the relative standards in the USA and Japan. The standard in the USA is NFPA 13 which is formulated by NFPA, and the standard in Japan is HASS. This thesis uses NFPA 13 primarily to design a method improving the earthquake performance of the fire system. NFPA 13 requires installing appropriate elements to reduce the relative movement of the suspension pipes.
In order to prove the NFPA 13 is good, this thesis performed a shaking table test which was designed according to Puli parking building’s fire system. The result of this test indicates that NFPA 13 method could reduce the relative displacement to a fifth to tenth. Finally, this thesis utilizes SAP 2000 to analyze the
earthquake performance of the fire suspension system.
