The comparative Descriptive Research and Analysis of RCC Twisted and Traditional Buildings Using ETABS Software for Indian and American Codes

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 3.5m 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.
