A Review Paper on Seismic Pareformance of High-Rise Building using Bracing, Diagrid and Outrigger System

Abstract

As the population of world is increasing day by day the need for high-rise building grows equally to it, but as the height of buildings increases the challenge to tackle lateral load in building will difficult and challengeable for engineers and designers. To stabilize the building against lateral load there are number of structural system to resist lateral in building without any addition to building's overall plan area or tonnage of the building. One of the most commonly used structural system that is used for stabilization of high-rise building against lateral load is bracing system, it can be used in both condition of the building it can be used as retrofitting or as system in design of the building. It transfer lateral load by means of tension and compression action. Another system that is a new concept that changes vertical columns orientation to diagonal that changes all types of load to axial load to transfer them safely to the foundation. One of the structural systems that can be used as lateral load resisting system that adds to the buildings lateral stiffness and strength is outrigger system that is very effective system in case of resisting lateral load. In current paper the above three mentioned system will be reviewed. Keywords-Lateral load resisting system, high-rise building, outrigger system, bracing system, diagrid system
