Abstract:
The primary focus of structural engineers is to determine how a structure will behave when exposed to horizontal forces. High-rise buildings must have sufficient stiffness to withstand the forces generated by wind and earthquakes. Shear walls, which are added to the interior of the proposed building, are used to counteract the horizontal stresses and lateral loads created by earthquakes as well as to give the structure more rigidity. This paper aims to study the usage of shear walls at different locations in a G+13 multi storied residential building and to study the nature of the structure exposed toearthquake by adopting Response Spectrum Analysis. The Multi storied building with G+13 is analyzed for story drift, base shear, base reaction, story shear, displacement and torsional irregularity. The analysis and modeling for the whole structure is done by using prominent FEM integrated software named ETABS 2016. In this thesis the dynamic analysis is carried out SD type stiff soil for different cases based on the location of shear wall (Case A: Building Without shear wall, Case B: Building with shear wall at two lower end, Case C: Building with shear wall at two upper end, Case D: Building with shear wall two end diagonally upper left and lower right, Case E: Building with shear wall two end diagonally upper right and lower left and Case F: Building with shear wall at four ends) and based on the zones of Bangladesh (Zone II, Zone III and Zone IV). It is concluded that the structure with shear walls Case F placed symmetrically will show better results in terms of all the seismic parameters when compared with other cases.
