Comparative Analysis for the Seismic Response of an Irregular Building With Floating Column and an Irregular Building Without Floating Column

The study is done to check the earthquake resistance of an irregular building with floating in comparison to an irregular building without floating and also the behavior of the two buildings during earthquake excitations and how safe they are in earthquake-prone areas. Analysis on these building models where carried out using the non-linear push over method of analysis to study the story responses of the building under earthquake excitations. A modal analysis was also carried out to check the period of vibrations for each building type. The analysis was carried with the extended three-dimensional analysis of building systems (ETABs) software. The results plotted are the story responses obtained after analysis, that is, the story drift, story displacement, story shears, overturning moments and story stiffness. The story drift and story displacements obtained show a higher drift and displacement in the building with floating column than the building without floating column. The periods of vibration for the two building models remained the same indicating that the presence or absence of a floating column does not affect the period of vibrations.
