  • Abstract:
  • High-rise buildings provide distinct challenges in terms of their construction and design. Managing lateral loads, especially lateral displacement, constitutes a considerable challenge in the design of high-rise buildings. Over the past century, researchers have devised numerous structural methods to control the sideways movement of a building. The outrigger structural system is a choice that involves placing deep beams, commonly referred to as outrigger beams, at various intervals across the building's height. These beams have a depth that matches the height of each level. The core, often positioned in the middle, securely bonds to the beams. Outrigger beams and a firmly attached core reinforce the structure's structural integrity. Belt trusses connect the entire perimeter of the system at the outrigger installation levels, increasing rigidity and creating a unified structure. Outrigger beams and a firmly attached core reinforce the structure's structural integrity. Without the need to expand any component, the structure reduces its lateral swings. Selecting the appropriate placement for these outrigger beams is of utmost importance for structural engineers. The number and placement of outriggers determine the outrigger structural system's overall effectiveness. Researchers have conducted several previous studies to determine the optimal location of outriggers on a steel building structure. However, we found no information about the construction of reinforced concrete outrigger systems in India. Additionally, we found no substantial literature demonstrating the effective use of this method in modern high-rise buildings, where increasing floor space exploitation is of the highest priority. This study examines the structural analysis of a reinforced concrete structure in Mumbai, India. The analysis entails introducing outriggers with a belt truss, but only at refuge levels. This design guarantees unrestricted human movement during a fire escape, making the analysis practical. Two models have been examined, one employing a traditional modelling system without outriggers and the other incorporating outriggers and a belt truss around each refuge floor. We conducted gravity, seismic, and wind analysis using the esse
