Structural type: Tube in tube tower steel structure Vertical subsystem: Outside framed tube + inside core tube Horizontal subsystem: Beam + floor subsystem
Vertical subsystem: Outside framed tube is formed by four facades. Each facade: 56 box-sectional column spaced with 1.02m center and connected by deep spandrel beams to form a rigid moment-resisting system. Each column is 450mm x 450mm steel box section
