India. ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract – In this research work time history analysis is carried out for G+23 RC building of square shape 52mX52m (plan configuration) frame structure without and with different steel bracing system viz. X, V, inverted V, Eccen Forward, Eccen Back. The member property of beams 300mm X 400mm and columns 300mm X 500mm and ISLB250 sections are used to compare for same patterns of beam, column and bracings. We provide different seismic and other parameters like Seismic Zone- III, Soil Site factor 2 for Medium Soil, Damping = 5% (as per table-3 clause 6.4.2), Zone factor for zone III, Z=0.16), Importance Factor I=1.5 (Important structure as per Table-6), Response Reduction Factor R=5 for Special steel moment resisting frame Table-7), Sa/g= Average acceleration coefficient (depend on Natural fundamental period)Grade of concrete is considered M25, Grade of Rebar is considered Fe-415, Grade of Steel –Fe-345,Dead Load for Wall 12.88 KN/m, Dead Load for Slab 3 KN/m2. . The property of the section is used as IS 456:2016 and per IS 800:2007 by using Etab Software and analyzed as per 1893-2016 by Response Spectrum Method. The comparative analysis is done in the term of storey displacement.

INTRODUCTION The concrete structure with Steel braced frame is one amongst the structural system comfortable repel the earthquake masses within the multistorey buildings, several existing bolstered cement concrete buildings must be retrofitting to beat deficiencies to resist seismal masses. the employment of steel bracing systems for strengthening or retrofitting seismically light concrete frames could be a viable answer for enhancing tremor confrontation. The primary purpose of every kind of structural systems employed in the building form of structures is to transfer gravity masses effectively. the foremost common masses ensuing from the result of gravity ar loading, load and snow load. Besides these vertical masses, buildings also are subjected to lateral masses caused by wind, blasting or earthquake. Lateral masses will develop high stresses, turn out sway movement or cause vibration. Therefore, it's important for the structure to own ample strength against vertical masses along with adequate stiffness to resist lateral forces. Strengthening of structures proves to be a more robust choice business to the economic issues and immediate shelter issues instead of replacement of buildings. Hence, we all know this retrofitting and while not retrofitting structure within which economical as compared to every different structure. Therefore, seismal retrofitting or strengthening of building structures is one amongst the foremost vital aspects for mitigating seismal hazards particularly in earthquake prone areas. 1.1 BUILDING CONFIGURATIONS Fig.1a: Building Plan Fig.1b: Elevation without Bracing
