When rocks are deformed, enormous amount of energy is released, the resulting vibrations spread out in all directions. An earthquake is the passage of such vibrations resulting vibrations spread out in all directions. An earthquake is the passage of such vibrations. The seismic force canabe resolved into 3 perpendicularmdirections that is 2 in horizontalmdirections (x and y) and the remaining 1 in verticalmdirection (z) The main objectivesaof this work are to know the behaviouraof a multi-storey vertical irregular residential building under lateral loads. The project is carried out by FEM software E-Tabs. The building model used in this work has 15 stories each storey has a height of 3m. Five different models are used in 4 different zones and their effects are tabulated in Results.
