Sometimes "faced" (meaning to have a paper covering on one side) or "unfaced" (without paper). Outriggers provide increased stiffness and so can reduce building drift (the sway experienced at the top of very tall buildings), thereby reducing the building accelerations during strong winds which might otherwise cause discomfort to occupants. Outrigger beams which are not stabilized by bolts or other direct connections to the floor or roof deck shall be secured by tiebacks. The same principle has been used since the 1950s in construction to provide lateral stability to tall, narrow buildings. The outrigger and belt truss system is one of the lateral loads resisting system in which the external columns are tied to the central core wall with very stiff outriggers and belt truss at one or more levels.

Dynamic architectural approach sets out to restore and improve the environment. NB Outriggers may also be used to stabilise construction plant, such as mobile cranes, which might otherwise overturn. The belt truss tied the peripheral column of building while the outriggers engage them with main or central shear wall. outrigger - a stabilizer for a canoe; spars attach to a shaped log or float parallel to the hull If you continue to use this website without disabling cookies, we will assume you are happy to receive them.

They can be tied to the core and combined with exterior columns, or may be connected to a super- or mega-column. The structural efficacy of outriggers will depend on their distribution through the building’s height, the number of outrigger levels, their configuration on plan, the depth of the outrigger truss or wall, the materials used and other considerations.
