The goal of this project is to use Response spectrum analysis to investigate how a twisted building responds to earthquake and wind loads. ETABS 2018 is used to carry out the analysis. In the study, a building model with G+25, G+30, and G+35 storeys and a constant storey height of 3.1m was used. For this study, analysis and design are done in accordance with Indian Standard Code. A tall building's stiffness can be viewed as an indirect indicator of how vulnerable it is to dynamic forces. This effect is influenced by the wind speed and the building's aerodynamic characteristics. As a building's height grows, the wind load value rises. High spatial stiffness raises the natural vibration frequency, which for low values might be hazardous for construction, while reducing the acceleration linked to a structure's horizontal displacements. At certain wind speeds, the structure can enter a resonance that results in severe stresses and vertical displacement. The aerodynamic twisted design has the benefit of disrupting the direction of the wind's impact around the building, which helps to significantly lessen wind excitation. While designing all the forces that induce on the building were considered and in Post analysis of the structure, maximum shear forces, bending moments, maximum storey displacement, behaviour of building to seismic force, storey stiffness, storey drift and other reactions are computed.
KEYWORDS
1) When the rotation of the structure is increases then the base shear is also increasing the total 3.1D structure base is higher than the remaining the structure. The base shear is 1% to 11% increases as compare to the other structure. 2) The maximum storey acceleration of the structure is 1.1D is increased by 14 %, 14.01%, 8%, and 16% as compared to the 2D, 2.1D, 3D and 3.1D when we decrease the twisted angle then the acceleration increases. 3) The Storey Stiffness 2.1D is increases by 6-7% around but 1.1D is decreasing by 66% around means when we increase the twist angle of floor then the Stiffness also increases. 4) The overturning moment effect of the all structure all near about the same the only 1-2% slightly increases 2.1D structure. Means no effect of floor rotation on the moment. It was increased when increases the storey height. 5) The maximum storey displacement of the structure 2.1D is increase 6% as compared to other type of structure all around displace nearly same means when we twisted the floor displacement is decreases. 6) When we increase the rotation of the floor then the modal time period also decreases 7) The maximum storey acceleration of the structure is 1.1D is increased by 2 %, 1.1%, 3%, and 1.8% as compared to the 2D, 2.1D, 3D and 3.1D when we decrease the twisted angle then the acceleration increases. 8) storey stiffness is for 1.1D Is increasing by 43 %, 31%, 33.1% and 26.4% as compare to the 2D, 2.1D, 3D and 3.1D model 9) The overturning moment is for 1.1D is increasing by 41 %, 33.4%, 31.1% and 24.4% as compare to the 2D, 2.1D, 3D and 3.1D model. 10) The maximum storey displacement of the structure 2.0D is increase 6% as compared to other type of structure but only 10% 1.1D type of structure. the displacement is varying for floor to floor. 11) When the rotation of the structure is increases then the base shear is also increasing the total 3.1D structure base is higher than the remaining the structure. The base shear is 4% to 12% increases as compare to the other structure. 12) When we increase the rotation of the floor then the modal time period also decreases
