In this study, the genetic algorithm-based optimal seismic retrofit method using buckling restrained braces (BRBs) for existing steel frames was presented to simultaneously minimize the two conflicting objective functions of initial retrofit cost and lifecycle cost. Method 1 provided the BRB placements and sizes and was applied to a nine-story steel frame; the effectiveness of the retrofit schemes obtained was then investigated. Although it is important to ensure the vertical continuity of BRBs for preventing soft and weak stories, little research has been reported on the optimal seismic retrofit method to suggest the installation placements and sizes of BRBs. Therefore, an additional optimal seismic retrofit method was proposed to enforce the vertical continuity of BRBs. The results indicated that the proposed methods were more effective than the conventional retrofit method, and in some retrofit schemes, the vertical continuity condition incorporated into Method 2 presented greater initial retrofit costs than those of Method 1 to yield similar lifecycle costs.
