It is a big challenge that the tall buildings must withstand the various forces acting from different directions and aspects such as seismic and wind forces while designing the tall structures it is mandatory to deeply understand the seismic and wind behaviour of multi-storeyed buildings. In this study we are concerned to determine and analyse the seismic and wind behaviour of high-rise buildings some of which were regular and other had irregularities in them in their plan and elevations. Three G+30 storied buildings were considered which were situated in seismic Zone-V and analysis were carried out using response spectrum method as per IS 1893- 2016 on ETABS software. Each building is subjected to wind load at different terrain categories to examine its effects at different slopes as per IS 875 Part 3 2015.Various parameters like Auto lateral load, maximum storey displacement, maximum storey drift, over-turning moment, storey shear and time period were considered in this study. It is concluded that vertical irregular building in terrain category-4 with ground slope less than 3 degree's provides greater resistance against both seismic and wind loading among all buildings.
