Comparative Study on the Seismic Analysis and Wind Analysis of Multistorey Building with Shear Wall and Diagrid

The present study investigates the behaviour of G+50 storey octagonal shaped building provided with shear wall at different locations and diagrid, by inter-combining all these parameters of shear wall and diagrid; total six model of G+50 storey building are prepared. The seismic and wind analysis of G+50 storey building is carried out by using structural analysis and design computer program STAAD Pro. The dynamic analysis (Response Spectrum Method) of G+50 storey octagonal shaped building with shear wall at a different locations and diagrid is carried out by using structural analysis and design computer program STAAD Pro. All the models are developed for seismic zone III as per IS 1893: 2002 (part I) and for wind analysis zone II is considered i.e. Aurangabad city having a basic wind speed of 39 m/s as per IS 875: 1987 (part-III). All the models are analyzed by considering seismic forces and wind forces. The main aim of this research work is to find out the suitable location of the shear wall and the model under seismic forces and wind forces which give optimum results. The behaviour of each model with respect to others is checked for Base Shear (VB), Axial Force (FX), Twisting Moment (MX), Bending Moment (My), Bending Moment (MZ), and Lateral Displacement (δ) at each and every storey are carried out for seismic forces and wind forces separately. Finally, the behaviour of each model with respect to others for seismic force and wind force is described with the help of graph.
