What is Outrigger?
Outriggers are inflexible horizontal systems constructed to enhance building overturning rigidity and strength by way of connecting the building core or spine to distant columns.
Benefits of Outrigger system
In a building with a central core braced frame or shear walls, an outrigger system engages perimeter columns to eﬃciently reduce building deformations from overturning moments and the resulting lateral displacements at upper ﬂoors. A tall constructing structure which includes an outrigger system can revel in a reduction in center overturning moment as much as 40% as compared to a loose cantilever, in addition to a signiﬁcant reduction in flow depending at the relative rigidities of the core and the outrigger system. The system works by way of applying forces at the center that in part counteract rotations from overturning.
For structures with belt trusses that interact all perimeter columns, columns already sized for gravity load may be capable of resisting outrigger forces with minimum adjustments in size or make stronger, as diﬀerent load factors apply to layout combos with and without lateral loads. Within the event that extra ordinary ﬂexural stiﬀness is required, the greater lever arm at outrigger columns makes extra material extra eﬀective than within the center. Outriggers may also permit optimization of the overall building machine using strategies such as unit load technique to identify the great places for additional material
A separate but related benefit is force reduction at center foundations. Outrigger structures assist to eﬀectively distribute overturning loads on foundations. Even wherein a basis mat is prolonged over the whole tower footprint, a center most effective lateral device applying huge local forces from overturning can generate such large mat shear and ﬂexural needs, in addition to net anxiety in piles or lack of bearing, that the layout becomes uneconomical or impractical. decreasing core overturning and concerning perimeter column axial.
