The behaviour of a building during an earthquake depends on several factors such as stiffness, adequate lateral
strength, ductility and configuration. The buildings with regular geometry and uniformly distributed mass and stiffness in plan
as well as in elevation suffer much less damage compared to irregular configurations. The aim of this study is to evaluate the
seismic behavior of RC building having different types of irregularities, mainly vertical geometric irregularity and stiffness
irregularity
