The site for this project is rectangular, with a north-south length of approximately 95 meters and an east-west width of about 73 meters. There are two above grade building blocks. Block A is 19 levels above ground with a total height of 91.7 meters, block E is 17 levels above ground with a total height of 91.7 meters. There is a five levels basement with a total excavation depth of 20.05 meters.

Project Details
Location: Taipei, Taiwan Gross Building Area: 49,779 m^2 Scope of Service: Schematic design through construction administration Client: Jin Yu Tai Co., Ltd. Architect: CHL Architect & Associates (Taipei, Taiwan) Structural Engineer: King-Le Chang & Associates |
The primary structural system of block 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. In order to reduce wind-induced acceleration, viscoelastic dampers (VED) are installed, with six groups in the X-direction and four groups in the Y-direction, totaling 110 groups from the 5th to the 15th floors. Additionally, in order to control floor vibrations, 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, from the 2nd to the 19th floors.
The overall structure of block E 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. In order to reduce wind-induced acceleration, six groups of viscoelastic dampers (VED) are installed in the Y-direction, totaling 48 groups, from the 5th to the 12th floors. Additionally, in order to effectively control floor vibrations, long-span beams are fitted with tuned mass dampers (TMD) with two groups per floor, totaling 32 groups, from the 2nd to the 17th floor.
