Earthquake Safety : The building employs an advanced structural engineering system which fortifies it against typhoon winds of up to 200 km/h (with the top swaying by a maximum of 75cm) and earthquakes of up to 7 on the Richter scale. The steel shafts have shear joints that act as shock absorbers to cushion the lateral forces imposed by winds and quakes, and the swimming pool on the 57th floor is said to act as a passive damper.

Special Design Features :Its postmodern form, whose complexity rises as it ascends, draws on traditional Chinese architecture such as the tiered pagoda, gently stepping back to create a rhythmic pattern as it rises. Like the Petronas Towers in Malaysia, the building's proportions revolve around the number 8, associated with prosperity in Chinese culture. The 88 floors (93 if the spire floors are counted) are divided into 16 segments, each of which is 1/8th shorter than the 16-story base. The tower is built around an octagon-shaped concrete shear wall core surrounded by 8 exterior composite supercolumns and 8 exterior steel columns. Three sets of 8 two-story high outrigger trusses connect the columns to the core at six of the floors to provide additional support. Observation Decks: The 88th floor houses the Skywalk, a 1,520mē indoor observation deck with a capacity of 1,000+ people
