Outrigger Braced System Comparison with Various Lateral Load Resisting System in Multistorey Building

In this study, we look at three types of lateral load resisting systems: outrigger braced systems, diagrid systems, and shear wall systems. Outrigger bracing is a solution for controlling excessive drift and displacement in high-rise buildings. It is made up of outrigger bracings or outrigger trusses that connect the central core of the building to the peripheral columns, and the peripheral columns are connected to one another via belt trusses. For the 20 storey building heights, the conventional structural model with a reinforced concrete central core and models with outriggers at the top, top and 0.75H, top and 0.5H, and top where H is the total height of the building are modelled. Finding the perfect location for the outrigger system is the study's major goal. discover the most effective lateral load resisting system at the lowest cost. According to the findings of many evaluations, the top and middle heights of a high-rise building, where top displacement and drift are at their lowest, are the best places to install an outrigger bracing system. In comparison to traditional, diagrid, and shear wall constructions, outrigger structures are more rigid. The largest reduction in storey displacement, base shear, and minimal loads on slabs were demonstrated by the top and 0.5H type of outriggers.
