Multistory Building of Regular and Irregular Configuration Under Earthquake Conditions

The shape of a building plays a vital role in the behavior of the building in a lateral loading condition. As the building moves its center of gravity also moves depending upon the displacements. Irregular buildings may have its center of gravity away from its centroid which may have negative consequences in lateral loads. Thus the behaviour of a multi-story building of regular and irregular configuration under earth quake is complex and it varies of wind loads are assumed to act simultaneously with earth quake loads. In this paper a residential of G+13multi story building is studied for earth quake and wind load using ETABS. Assuming that material property is linear static and dynamic analysis are performed. These analysis are carried out by considering different seismic zones and for each zone the behavior is analysed. The seismic zones considered are taken from V. Different response like story drift, displacements base shear are plotted for different zones. Winds are assumed to be on medium scale. Cyclonic winds are not considered for this paper.
