The space requirement is the major problem which results into the congestion of structures and also they
are very unsafe whenever lateral forces i.e. earthquakes forces are experienced by the structures. Podium is the
structure which is used as a multi-usage platform for making the regular or irregular structures. Podium may consist
of commercial to certain height, residential and also for many other purposes. Hence in order to fulfil the space
requirement and also for the safety purpose the podium structure and its analysis is been made. In the present study the
dynamic analysis is been done. Also the dynamic analysis is been carried out by the response spectrum method. The
aim of present work is to study the performance of podium type building with different irregularities under dynamic
loading for different storey heights and to compare the results in terms of different parameters. For comparison 15, 20
and 25 storeys buildings having same podium size respectively are considered. For dynamic analysis of members IS:
1893-2002 design code is considered. For modelling and analysis of structural member in terms of time period, storey
displacement, storey drift, storey shear and torsion effect under dynamic loading. For the dynamic analysis ETAB V.16
software is used.
