Effective Location of Different Outrigger System in Seismic Respond RCC High Rising Building Using ETABS

Abstract: The rapidly growing number of high-rise structures around the world poses new obstacles, and lateral stiffness becomes one of the most critical issues as building height rises. The lateral stiffness and resistance capacity of high-rise buildings have a significant impact on structural efficiency, and structural engineers have introduced numerous capable constructions. The outrigger system is one of the most frequent and effective lateral loads resisting structural systems for improving structural stiffness and stabilizing the structure. The core shear wall provides structural strength in the main structural system, while the outrigger like X bracing adds lateral stiffness. In this study building with the outrigger and shear wall system has been analysed by Response Spectrum Analysis, The concept of illumination of outrigger structural systems is evaluated by comparing multiple X braced outrigger system and shear wall system models types utilizing a 25-story reinforced concrete building using ETABS software under seismic load to better understand the performance and load transferring mechanism of outrigger system.
