Responding to an array of conditions in Shanghai, Gensler’s team proposed a building design that employs a curtain wall system designed as a symbiosis of two glazed walls—an exterior curtain wall (Curtain Wall A) and an interior curtain wall (Curtain Wall B)—with a tapering atrium in between. The main support for the exterior curtain wall is a horizontal ring beam consisting of a horizontal pipe 356 mm in diameter laterally supported, at 0 meters on-center in Zone 2 and 7 meters on-center in Zone 8, by a radial pipe strut support. This variation is a result of the geometry that included tapering and rotation of the tower.
