In this day and age of urbanization, there is a strong need for a large-scale high-rise apartment building in every city but high-rise construction systems are extremely difficult to construct in any seismic region due to the intense and disruptive nature of seismic forces. Seismic forces have the highest risk of causing the most harm to high-rise buildings. To meet this need, the Civil Engineering industry is constantly developing new groundbreaking techniques. To solve this problem RCC or steel bracings are provided in high-rise buildings which help to the low down the effect of seismic and wind forces. The main objective of this paper is to locate an effective position and pattern of the RCC X-bracing system in the L- shape multi-storey building which is subjected to seismic forces. According to a previous reference paper, X-bracing produces better results than other bracing systems. Analysis the seven types of frame models are taken – (1) Normal L-shape building without bracing, (2) Xbracing are provided at the face of L-shape building, (3) X-bracing are provided alternative pattern at the face of L-shape building from bottom to top floor, (4) X- bracing are provided zig-zag pattern at the face of L-shape building, (5) X-bracing are provided at the corner of L-shape building, (6) X-bracing are provided alternative pattern at the corner of L-shape building from bottom to the top floor, (7) X-bracing are provided zig-zag pattern at the corner of L-shape building. Developed and evaluated by response spectrum analysis method (Linear dynamic analysis) as per IS 1893-2000 using STAAD PRO V8i. In the present work G+12 storey, the L-shape frame structure is analyzed by using X-bracing. It is analyzed and the results of the Following Parameters are taken - (1) Peak storey shear, (2) Base shear, (3) Nodal displacement, (4) Maximum bending moment, (5) Total quantity of steel in the whole structure, (6) Total volume of concrete in the whole structure are evaluated and compared.
