Analysis and Design of Twisted Skyscraper Building Using ETABS
Javed Shaikh,  Arbaz Shaikh,  Gaus Patel,  Shazeb Sayed,  Rafiq Tinwala
The objectives of this paper is to study the behavior of a Twisted Skyscraper Building subjected to earth quake load and wind load by adopting Response spectrum analysis .The analysis is carried out with the help of FEM software’s ETABS 2018. The building model in the study has G+50 (52) storeys with constant storey height of 3.5m.According to the Indian Standard Code Analysis and Design are carried out for this study. The stiffness of the bearing structure is a superior criterion in the shaping of such buildings and its value lies in the size of permissible vertical deflection. Limitation of the vertical deflection of a high-rise building is not only aimed at preventing and minimizing the adverse P-delta effects on the structure of the building. The stiffness of a tall building can also be considered as an indirect indicator of its susceptibility to dynamic influences. This impact depends on the strength of the wind and on the aerodynamic properties of the building. The value of the wind load increases with the height of the building. High spatial rigidity reduces the amount of acceleration associated with the horizontal displacements of a structure and also increases the natural vibration frequency, which for low values can be dangerous for construction. The structure can fall into resonance at critical wind speeds, which generates both high stresses and vertical deflection. The aerodynamic twisted shape has the advantage of disturbing the form of the impact of wind around the building to effectively reduce wind excitation
