Based on recent earthquakes in Taiwan, losses do not necessarily result from the damage of building structures but rather from non-structural components and systems. For instance, the leakage of the fire protection sprinkler systems in hospitals during small earthquakes can result in the shortage of medical functions and fire protection, and the malfunction and repairs of medical equipment. The breakage of sprinkler systems caused by strong earthquakes can even harm the safety of buildings. Taking a sample sprinkler piping system in a medium-scale hospital as an example, this research aims to verify seismic strengthening strategies based on NFPA 13 to improve the seismic performance of fire protection sprinkler systems in critical buildings. The design concepts, which include numerical analysis simulating the original piping, the design of input motion, and the test specimen, and a strengthening strategy established based on the consideration of improving the seismic performance in specific damage states, were introduced. Additionally, preliminary results of shaking table tests for four strengthening strategies are discussed to propose a more applicable seismic design guideline for sprinkler piping systems in Taiwan. |
