초록  In this study, the structural analysis of sway brace device for earthquake-proof which can fix a pipe installed in the building was carried out. The sway brace device was analyzed to evaluate not only the deformations of adaptor fitting, support brace member, structure attachment fitting and clamp sway brace fitting that compose it, but also the effective stress of adaptor fitting combined with support brace member by shear bolt. As a result of structural analysis, it can be seen that the deformation of support brace member influences most of the deformation of sway brace device and the design of adaptor fitting must be modified. Above all, it indicates that the sway brace device is suitable for Korea Fire Institute(KFI) approval standard since its total deformation is smaller than the maximum displacement proposed by KFI. The result of this study can be effectively used to investigate the effective stresses and deformations without the performance test of sway brace device according to its setting angle.
