Irregularities are not avoidable in construction of buildings. However, the behavior of structures with these irregularities during earthquake needs to be studied. Present study represents the behavior of regular and irregular building. In this present study five storey building is considered having 5 bays in both direction with 4meter bay span. The building is modelled in ETABS-2013. In this paper two types of irregularities are considered like re-entrant corner and diaphragm discontinuity. Here four models of diaphragm discontinuity and four models of re-entrant corner are prepared. Four models of diaphragm discontinuity are denoted as D1, D2, D3 and D4, similarly for models of re-entrant corner are denoted as R1, R2, R3 and R4. For analysis purpose various loads are considered like dead load, live load and earthquake load in X and Y-direction. Various loads combinations are considered according to IS-1893:2002. The various parameter like storey drift, storey displacement, torsional displacement and height to weight ratio are considered for comparison. It is observed that storey drift and storey displacement for D1 model as compared to other model in Y-direction is greater than the X-direction. Value of torsional displacement is only existing for model R1 and R4. Torsional displacement is zero for remaining model other than R1 and R4 due to symmetry structure. It is also observed that value of displacement and drift is also depend on the height to weight ratio. Further it is observed that value of displacement and drift decrease as the height to weight ratio increases.

Re-entrant corner, Diaphragm discontinuity, Storey drift and displacement, Torsional displacement.
