Located in Seoul, Korea, the Lotte Super Tower is a unique form that transforms from a square, 70- meter square footprint to a 39-meter circle at 555 meters above ground. The shape of the building has been refined to reduce wind forces and accelerations. A dual system comprised of an exterior steel diagrid and an interior reinforced concrete core is utilized for lateral resistance to wind and seismic effects. Each of the components of the structural system have been optimized to provide material efficiency, and geometrically rationalized to increase constructability. When completed, the Lotte Super Tower will be the second tallest building in the world.
