Shanghai Tower - Design and Construction Challenges of the Tallest Building in China (2,074 ft.) [N62]

This presentation discusses the structural system, analysis and design challenges of the 126-story, 632-meter (2,074 ft) tall Shanghai Tower, one of the tallest buildings in the world. For economy, this tower uses a unique ""Core-Outrigger-Mega Frame"" lateral system. Steel and reinforced concrete (SRC) super columns and box steel belt trusses at mechanical equipment levels form a perimeter Mega Frame to provide additional stiffness and strength to the whole lateral system. The twisting exterior facade is created by an innovative double-skin architectural design. The outer skin is supported on a unique structural system resembling a bicycle wheel in plan. Performance Based Design studies were performed to verify tower performance under different seismic conditions.
