In this study, the design procedure for steel frame with bucking restrained braces taking into account dynamic soil-structure interaction was proposed satisfying the given target displacement under design earthquake. The buckling restrained braces of the structure which was modeled as shear building model supported by swaying and rocking springs and dashpots corresponding to the ground system were designed using inverse stiffness method. It is expected that the present design method could be utilized in the preliminary design without ambiguous re-selection and irrational repetition procedure. To verify applicability of this design method 3, 5 and 10-story structures were applied with 2 ground conditions, 3 ratios of the second-branch stiffness to the initial stiffness and 5 given target displacements. For each cases, the results were compared with fixed-end model's results taking no account soil-structure interaction.
