Abstract
The present analytical seismic research deals with the optimal alignment of steel bracing to the RC system by means of response spectrum analysis with unsymmetrical building plan of G+30 floors in zone 5 following IS 1893(part-1):2002 and IS 13920:1993. Various steel bracing systems such as X, Single Diagonal, Inverted V braces are available at different structural locations. Within the story, braces are connected and five different types are considered in more than one story. Compared to the bare frame, the tests were compared to five styles and the optimal bracing position. Compared to lateral displacement, story drift, story stiffness, base shear, story torsion, eccentricity, and time period, the structure's response. Earthquake Engineering's sector has been around for many years. Earthquake engineers made significant contributions to the seismic protection of the country's many major structures. Braced frames were an important and useful tool for strengthening structures against lateral loads in comparison to other structural systems, such as moment-resistant frames or shear walls. In seismic excitations, inclined elements react as web truss elements that would bear stresses of compression or tension. This axial reaction results in fewer moments and thus smaller sizes in beam and column parts compared to members in equivalent resistant frame moments. Two separate Unsymmetrical RCC framed buildings are therefore studied in this study, one braced and another un braced subjected to lateral loads. Seismic analysis is conducted using Etabs technology to test the building according to IS 1893:2002 for various load combinations. Based on floor displacements, storage drifts, base shear, axial force and bending moments, the comparison is made between the braced and un braced building. It has been observed that the braced building's seismic performance is improved compared to the unbraced building.

Keywords- Seismic analysis, Earthquake, Seismic research, unsymmetrical buildings, unsymmetrical frames, bracing systems.
