INTIGRATION OF EXOSKELETON STRUCTURE IN MID-RISE STRUCTURE

Abstract

Stiffness and Drift is a primary concern of a structural designer in the design and maintenance of structures, as reduction in stiffness and increment of drift can lead to the failure of whole structure which cause economic and safety consequences. This study investigates the stability of a already existing structure using ETABS, widely used for analysis structures under different loading condition. The research focuses on comparative study of mid-rise structure with exoskeletal under the lateral loading. Obtained analysis disclosed that retrofitting with the exoskeletal system enhanced the structure lateral displacement, drift and stiffness under seismic and wind loading. The study foregrounds the role of exoskeletal in enhancing the overall stability and performance of mid-rise structures under lateral loading conditions, providing valuable cognizance. Analysis under seismic and wind loads stipulate that the maximum lateral displacement for a structure without exoskeletal is higher in comparison to structure without exoskeletal, demonstrating the reduction in lateral displacement with exoskeletal. The study seeks to identify that depletion in lateral displacement for structures with different orientation of bracing in steel exoskeletal, flawless orientation of bracing in steel exoskeletal showing the maximum reduction in lateral displacement under lateral loading conditions. The study highlights the effectiveness of Exoskeletal as a retrofitting technique. They serve as a fixed supporting system for the structure and increase the overall stiffness and reduce the displacement studied under response spectrum analysis.
