This paper presents design recommendations for optimal seismic response control of damped braced tube system with focus on cost performance of introducing energy-dissipation devices. According to the results, 1) braced tube structure should be designed so that coupled-shear-wall-like vibration modes are predominant to obtain highly damping ratio and better cost performance of dampers, 2) oil damper should be introduced to obtain highly damping ratio, 3) BRB has good cost performance about seismic response reduction and can be used to reduce damper costs.
