In the event of an earthquake, structures are shaken in various ways, resulting in side-sway between stories of a structure. When side-sway occurs in a building due to an earthquake, the facilities installed in the building are also affected. In particular, the facilities that connect a lower floor to a higher floor, such as riser pipes, are significantly affected by sidesway. In this study, a steel frame realizing the second floor of a structure was fabricated, and a riser pipe with pressure joints was installed in accordance with NFPA 13. Moreover, the seismic behavior of the riser pipe was analyzed by conducting cyclic loading tests on the maximum allowable amount of sidesway. Furthermore, the deformation angle, strain, and stress required to assess the seismic performance of the fittings and joints of the riser pipe in the event of a seismic load were also analyzed.
