Council on Tall Buildings and Urban Habitat
 

Outrigger Design Working Group
 
Outrigger systems have been widely used in super tall buildings since the 1980’s, eclipsing the tubular frame systems previously favored.  However, the outrigger system is not listed as a seismic lateral load resisting system in any code, and design guidelines are not available.  As outrigger systems become more commonplace in tall building design, CTBUH recognized the need for general guidelines and thus formed the Outrigger Working Group.
