Recently, the incidence and magnitude of earthquakes have been continuously increasing. NFPA 13 requires that hydroponics fire extinguishing system pipelines apply seismic isolation. Stainless steel joints have been newly developed to replace these seismic isolation joints. Therefore, in this study, a nonlinear finite element model of a pipeline with Stainless Power Joint was developed based on experimental data, and finite element analysis was performed by applying hydrostatic pressure and cyclic loading.
