“…The building consists of two types of columns one circular and another rectangular of dimension 500mm and 400x700mm respectively. The slab is of 125mm.The type of steel we have used for bracing is ISMB 350, where details about the bracing is shown below [12].…”

While constructing a building the most important factor to be considered is its strength. Strength against different types of load that will be act on the structure after absolute construction. The most important type of load to be considered while construction is lateral load, cause not every structure can sustain lateral loads, especially high-rise structures build on earthquake prone areas. In order to resist lateral loads on such areas either the structure should have columns of higher section or we need to add shear wall or bracing to the structure. Bracing and shear wall provide lateral support to any structure. Bracing as well as shear wall takes the extra load of columns and beams during an earthquake which helps in load balancing. In this paper we have made a G+7 building and did earthquake analysis on STAAD.PRO software as per zone V. When earthquake load is applied to the structure without braces some of the columns an beams fail so in order to make the structure stable we applied braces (X and Diagonal) to the same structure and then compared the three models based on maximum storey displacement, maximum storey drift, bending moment, shear force and base shear.

Parking spaces, lobby areas, terrace gardens, and other amenities are highly sought-after in densely populated urban regions. Although floating columns can be useful and an achievable choice, it is important to research their structural performance and cost-effectiveness in the event of substantial ground motion imposed on by an earthquake. A building’s overall dimensions, geometry, and shape all impact how it acts and acts when subjected to seismic loads. For this reason, it is necessary to assess how well floating column buildings perform in seismically vulnerable places in comparison to conventional buildings. In this work, the performance of structures with floating columns for seismic loading is observed using dynamic analytic techniques in accordance with IS 1893 (2005). This study analyses both the floating columns and the conventional building without floating columns. When compared to a regular building, the research reveals that the floating column buildings exhibit a very quick increase in base shear and story displacement. The horizontal displacements experienced by floating column buildings are proportionally larger due to an increase in the fundamental time period. If the lateral displacement exceeds the codespecified maximum limit, damage to structural and non-structural parts may result. Because of the discontinuity in the load distribution path, seismic base shear and overturning moment are also increasing in the case of buildings with floating columns. Additionally, while asymmetrically introducing floating columns, torsional irregularity has been produced but the modal mass participation ratio has decreased. While it is true that the use of floating columns in high-rise structures allows for continuous open floor plans, they are also dangerous and susceptible in seismically active locations
