Analysis of G+7 Multistoried Building for Various Locations of Shear Wall Considering the Effect of Torsion Using Response Spectrum Method

Dynamic Analysis of a 8-storey building is done in this research paper and for this a irregular building has been taken into consideration. The research paper also considers the effect of change in the position of shear wall in the building plan and its effect on the structure during the analysis. Overall 8 cases of the various positions of shear wall has been considered separately and the comparative results has been seen. The building which we have taken for analysis is of irregular shape resembling the letter “L” in plan and has a height of 28.8 m. The dimensions are 25m along x direction and 30m along z direction. STAAD Pro v8i has been used for the dynamic analysis of 8 storied building. The analysis has taken into consideration the effect of torsion also and have been analysed as per IS 1893(Part 1): 2002. The building structure is considered to be made of M-20 grade concrete and Fe-415 grade steel. The factors considered for comparison are Peak storey Shear along both directions, Peak storey Shear along both directions considering torsion, Average Displacement along both directions and Drift along both directions. The structure considered is in Zone III in medium soil.
