The primary structural system of Building A's superstructure consists of a core and a perimeter special moment-resisting frame (SMRF). On the northeast side of the building, there are inclined columns that slope inward between the third and fourth floors. Two of these columns stop at the second floor due to a conflict with the basement driveway. From the 5th to the 15th floors, viscoelastic dampers (VED) are installed, with six groups in the X-direction and four groups in the Y-direction, totaling 110 groups to reduce wind-induced acceleration. Additionally, from the 2nd to the 19th floors, long-span beams in the Y-direction are fitted with tuned mass dampers (TMD), with four groups per floor, making a total of 72 groups, to control floor vibrations.
The overall structure primarily consists of special moment-resisting frames (SMRF). The main X-axis frames are located at EY1 and EY3, while the main Y-axis frames are at EX3 and EX8. Intermediate floating columns are used to enhance frame stiffness. On the east side, the frame has inclined columns that slope inward between the third and fourth floors, while on the west side, the floor begins to recede to EX3 from the fifth floor onward. From the 5th to the 12th floors, six groups of viscoelastic dampers (VED) are installed in the Y-direction, totaling 48 groups, to reduce wind-induced acceleration. Additionally, long-span beams are fitted with tuned mass dampers (TMD) on each floor from the 2nd to the 17th floor, with two groups per floor, totaling 32 groups, to effectively control floor vibrations.

The previously mentioned tuned mass damper (TMD) was a vertical type designed to reduce floor vibrations, unlike the horizontal TMD, which enhances the overall structural stiffness and is effective in minimizing vibrations caused by wind loads.
