This project is about the performance of the torsionally balanced and torsionally unbalanced structure also called symmetrical and unsymmetrical structure. In this project, the effort is made to study the effect of eccentricity between the centre of mass (CM) and the centre of stiffness (CR) on the performance of the buildings. Three buildings of a storey (G+10) are used in this paper, likes Symmetrical, Unsymmetrical, and Unsymmetrical with cantilever section. The performance of a multi-storey framed building during study earthquake motions depends on the distribution of mass, stiffness, and strength in both the horizontal and vertical planes of the building. During earthquakes, there is strong earth-shaking, hence the earthquake-resistant design of structures is required. As now day’s unsymmetrical structures with cantilever sections are used to utilize the area and available space in a very efficient way. So, it is required to study the seismic behavior of unsymmetrical structures with cantilever sections. In such types of structures, the centre of mass of the buildings does not correspond with the centre of resistance. This leads to inordinate edge deformation and shear forces in the unsymmetrical structure compared to a symmetrical structure. Hence, by reducing the difference between the centre of mass and the centre of stiffness, torsion effects can be minimized. The Dynamic response of the building during times of seismic irregularities depends on the stiffness characteristics of the building. The objective study is the comparison of sections used in large-span unsymmetrical cantilever structures to minimize the effect of torsion. The study is primarily focused on the deflections of cantilevers of large spans under different loading conditions such as dead load, live load, and seismic load. The study also focuses on, to identify an appropriate technique suitable for the analysis of large span cantilevers within the unsymmetrical structure.
