Abstract - RC Building In recent decades, the building industry has relied heavily on RC structures for the most practical content. Seismic design is primarily used to provide strength, stability, and adaptability. It is necessary to build a structure that can withstand seismic loads. The system's structural bracing component has a significant impact on how the structure behaves during earthquakes. Massive steel-framed buildings' bracing patterns can alter how the worldwide seismic activity behaves.
In this study, a G+11-story RC frame building with a varied bracing system arrangement is subjected to linear static analysis. The dimensions of the beam (450 x 600 mm), the columns (450 x 700 mm), the thickness of the slab (180 mm), the density of RCC (25 KN/m3), the density of the masonry (20 KN/m3), the thickness of the wall (230 mm), the height of the parapet wall (1 m), the height of each floor (3.2 m), the live load on a typical floor (4.0 KN/m2), and the live load seismic calculation (0.75) are some of the parameters used in this work. Bracings are compared using different section types, such as ISMB350 sections. Steel buildings are analysed using the Staad Pro software program, which compares several parameters.
The section's properties are employed in accordance with IS: 456:2007 and IS 800:2007, which analysed several bracing types, such as X, V, and without bracing, and compare the performance of each frame using the linear static method.
In this research, a G+11 with a square building plan measuring 20 m by 28 m, with 3.2 m for each level, is modelled. The structure is constructed using the linear static method in Staad Pro software, and an earthquake analysis of the structure is conducted in seismic zones III with medium soil conditions.
