Dynamic analysis of High rise steel structure with RC shear wall and outrigger
Publication Date : 15/11/2018
Tall building development has been rapidly increasing worldwide introducing new challenges. In tall structures high lateral forces develops due to wind load and earthquake load are crucial. Thus the effect of lateral loads need consideration for strength and stability of the structures. The Outrigger in structures provides lateral stiffness that provides significant drift control for tall buildings. The study includes Rigid Frame, Shear Wall/Central Core, WallFrame Interaction and Outrigger effect on tall structures. The objective of this study is to know the performance of outrigger structural system in high-rise building subjected to wind load and seismic load as per Indian standards. In this comparative study mainly the bare frame will be compared with Steel outrigger with core for the structural efficiency. In this comparative study, the static and dynamic behaviour of the composite structure for different models such as steel bare frame, steel frame with outrigger, steel frame with shear wall, steel frame with shear wall and outrigger, steel frame with shear wall openings, and Steel frame with shear wall openings and outrigger will be compared for the structural response of a 40 storey composite building frame situated in earthquake zone-II and zone-V using ETABS software.
