<p align="justify">Viscoelastic coupling damper (VCD) has emerged as a new damping system and a promising technology to enhanced the wind and seismic performance of supertall buildings. In this study, the effectiveness of VCD enhancing the performance of supertall building is investigated for an 80-story building; 338,25meters tall with coupled shear wall, outrigger, and belt-truss as the lateral load resisting system. It would be disadvantageous, the link beam experience damage considering the height of the building. VCDs as lieu of conventional reinforced concrete link beam are expected to be able to solve those problems. Performance-based analysis will be conducted using non-linear pushover and time history analysis using seismic that represent Jakarta to identify the damaged of existing link beam. Then, VCDs will substitute the damage link beams. From the analysis, there are 2 damage link beams occurred. <br /> <br /> The structural performance level between the original one and the one with VCDs as the substitute of damage link beams are compared. The existence of VCDs installed result to force redistribution of the structural element. A number of elements accepts lower forces. On the other side, the number of the damage structures is increasing, most of them with a lower level of damage. The damaged coupling beams solved, but another coupling beam in the second-floor experience damage with a lower level of damage.<p align="justify"> <br />
