                                                   ABSTRACT


                 This project is a key part of the Taipei City Western District Gateway Project,
                 which includes two theme high-rise buildings, C1 and D1 tower. The Airport MRT
                 A1 station (i.e. Taipei Main Station) extends from basement level B3 to level 2,
                 where it is fully operational, and the two towers will be constructed on A1 station.
                 The investor, "Taipei Twin Towers Ltd.", commissioned the international architect
                 SOM to propose a new architectural scheme that would reconfigure the building's
                 massing, appearance, and spatial design while integrating it with the existing
                 structure, which also leads to numerous structural design challenges.
                 To achieve the overall architectural design philosophy, the building massing and
                 appearance were reformed via the application of structural dynamics and
                 aerodynamics, within an increment of heights forC1 and D1 towers to 280 and 360
                 meters, respectively. Meanwhile, to enhance the stiffness and strength of the core,
                 the D1 tower utilized Composite Plate Shear Walls - Concrete Filled (C-PSW/CF)
                 instead of conventionally Special Concentrically Braced Frames (SCBF). This
                 innovative system is combined with outrigger trusses to rigidly connect the core
