Abstract: In the present study, the behavior of plan irregular (C, T, I shaped irregular building and regular building) tall building subjected to the seismic load alongwith the importance of infill wall is considered. The modeling and analysis of (G+14) storey structure for seismic zone (III), soil type (II) with importance factor (1) and M20 grade concrete are carried out, by equivalent static and response spectrum method, as per IS 1893-2016(Part-1), using E-tabs 2015 commercially available software.. The results obtained are discussed in terms of base shear, storey displacement and storey drift. Many critical observations are drawn from the analysis. From these critical observations, it is concluded that, in almost all shape of plan irregular tall buildings, storey displacement and storey drift are found to be more in bare frame when compared with infill frame, whereas the base shear will be less in bare frame compared with infill frame. However, the results obtained amongst the different shapes, indicates that C, I and regular shaped tall building are yielding lesser storey displacement and storey drift compared to T shaped building. Presence of infill walls will increase the stiffness of the frame.
