design • The design has 2 statergies 1.asymetrical form of tower. 2.it’s triangular profile and rounded corners. • The wind tunnel test is used to find the most beneficial scaling factor of about 55% and rotation at 120°, which is account for the 24% savings of the wind load working on the structure. • typhoon-force winds that are common to the region, the architects designed an asymmetric form with a tapered profile and rounded corners — a form that reduced wind loads by 24% and saved $58 million USD in materials.



Structural design The Shanghai Tower lateral system : “Core-Outriggers-Mega Frame” Inner Cylindrical Tower • Concrete Composite Core • Exterior Mega Frame • Outrigger Trusses : Super Columns and Double Belt Trusses



• The core acts in concert with an outrigger and super column system. There are four paired super columns -two at each end of each orthonormal axis.



Lateral force resisting system



• • •



Steel I-sections are embedded in concrete, that supports the outrigger trusses. The double belt truss supported through main 8 columns support the curtain walls. The main 8 columns reduces in size as the building grows in height, to complement the reducing volume of building.



Shanghai Tower piled raft: The tower has a 5-storey basement, and its foundation depth is 31.4 [m]. The thickness of the raft under the tower is 6 [m] and the area of the raft is 8945 [m2]. The raft of Shanghai tower is supported by 955 bored piles with a diameter 1.0 [m].
