Outrigger Design for High-Rise Buildings

The Council on Tall Buildings and Urban Habitat's Outrigger Working Group has addressed the pressing need for design guidelines for outrigger systems with this guide, now in its second edition, providing a comprehensive overview of the use of outriggers in skyscrapers. This guide offers detailed recommendations for analysis of outriggers within the lateral load resisting systems of tall buildings, for recognising and addressing effects on building behaviour and for practical design solutions. It also highlights concerns specific to the outrigger structural system, such as differential column shortening and construction sequence impacts.
