Rapid urban population growth in emerging nations like India has compelled a revaluation of the significance of tall structures with varying dimensions and shapes, resulting in varying building aspect ratios. It has been established that a building's aspect ratio influences how an earthquake and wind act on it. There are various kinds of aspect ratios, primarily based on the building's height and geometry. The effectiveness of a structure in withstanding lateral loadings is influenced by the vertical aspect ratio, also known as the Slenderness ratio (H/B), and the horizontal aspect ratio, also known as the Plan aspect ratio (Lmax/Lmin). The building core size and the building slenderness ratio are the main factors that influence an efficient structural design. The design of mid-rise and low rise buildings differs from that of high-rise structures. Bureau of Indian standards has come up with special code IS:16700 which gives provisions for designs of tall buildings. The present study uses ETABS software to examine the seismic and wind load performance of a G+25 Storey RC Building with a plan aspect ratio of 1:2.6. The orientation of the building is changed at different angles with respect to the global X-axis and global Y-axis while keeping the wind direction constant in the software. Seismic parameters such as storey displacement, storey drift, time period and mass participation are obtained using Response Spectrum Analysis for seismic zone IV considering IS 1893–Part 1 (2016) codal provisions. Lateral displacement due to wind load is also determined as per IS 875–Part 3 (2015) codal provisions considering a basic wind speed of 47 m/s.
