Review on Behaviour of Outrigger Structural System in High-Rise Building
Ajinkya Prashant Gadkari,  N. G. Gore
Tall building development has been rapidly increasing worldwide introducing new challenges. As the height of the building increases, the stiffness of the building reduces. The Outrigger and Belt trussed system is the one of the lateral load resisting systems that can provide significant drift control for tall buildings. Thus, to improve the performance of the building under seismic loading, this system can prove to be very effective.
The outrigger and belt truss system is commonly used as one of the structural system to effectively control the excessive drift due to lateral load, so that, during small or medium lateral load due to either wind or earthquake load, the risk of structural and non-structural damage can be minimized. For high-rise buildings, particularly in seismic active zone or wind load dominant, this system can be chosen as an appropriate structure.
The objective of this paper is to study, the performance of outrigger structural system in high-rise RC Building subjected to seismic load and Wind Load. Study of the literature is reviewed in this paper on various aspects of outrigger structural system as; Behaviour of outrigger structural system in High-Rise RC building, Behaviour of Outrigger structural system in High-Rise Steel and composite Building, Behaviour of outrigger structural system in vertically irregular structures and Effect of seismicity on irregular shaped structure.
Keywords- Outrigger, Belt Truss, Lateral load resisting structural system, Irregularity, Non Linear Dynamic Analysis.
