Abstract:

The LG Kangnam Building in Seoul, Korea, is a multi-use, 140,000 sq m project, consisting of a 40 story, 183 m tall office tower, an adjacent 9-story acoustically base-isolated performing arts facility; and six subgrade levels of commercial and parking space. The asymmetrical shape and massing of the tower reflects the daylight envelope of the site, which controlled the height of the tower and the core offset from the geometric center. Nine m exterior column spacing led to the creation of a multi-story structural steel exterior braced system to control the building's response to lateral forces. The arts center is designed to minimize airborne and groundborne noise. There are two wall envelopes separated by a minimum of 200 mm of air space. Groundborne noise from nearby subways is controlled by vertical and horizontal acoustical joints at the structural interface with that of the adjacent office tower.
