ABSTRACT
Ten-story buildings are taken into consideration in this study. In ETABS-2018, the building is modelled with a shear wall, but the analysis does not take this into account. Different loads, such as dead, live, and seismic loads in the X and Y directions, are taken into consideration for analytical purposes. As per NBC 105:2020, different combinations of loads are taken into consideration. An attempt is made in this thesis to comprehend the seismic performance of buildings with and without shear walls. This project's primary goal is to determine if a building with or without a shear wall will fare better during earthquakes. The current study examines RCC building models that have G+9 stories and either a shear wall or no shear wall taken into account for analysis. The dynamic approach in the ETABS programme is used to analyse the model. Various seismic parameter categories, including base shear, drift, displacements, story stiffness, torsion, and forces in beams and columns in each model. In the end, the seismic behaviour of the structures is compared in terms of time interval, member forces, base shear, storey shear, overturning moment, displacement, stiffness, and drifts. It is found that model 1 performs better than model 2. The research also indicated that buildings with vertical irregularities have more venerable outcomes.
