Abstract
In this study, we compare the engineering seismic design method considering the physical properties of piping materials and the specification-oriented design method according to the seismic design standards of fire fighting equipment. In the case of the seismic design method considering the physical properties of piping materials, the safety of the piping will be analyzed through the combined value of the torsional stress and the bending stress generated in the piping. However, in the case of the design-centered design method, instead of the safety of the piping material, it calculates the moving force of the pipe and interprets whether or not the shaking prevention strut can bear. Fire extinguishing equipment piping is possible through safety analysis of stress and displacement of piping material because piping safety can not be secured via unstable force generated in a certain section with one connected structure is there. Therefore, it is necessary to apply analytical method considering seismic performance of building structure and material properties of piping for seismic design of safe fire extinguishing system piping.
