Irregular structures are a common phenomenon in modern day urbanization. Structures having significant physical discontinuities in vertical configuration or in their lateral force resisting systems are termed as vertically irregular structures. Irregularity is an inevitable occurrence in RCC frame structures now a days. The effect of this irregularity can be devastating. In this paper ABAQUS v.6.10 is used for finite element analysis through simulating stress analysis on irregular structure. The comparative finite element analysis between a regular and an irregular frame indicates that the maximum and minimum stresses varies significantly in particular nodes.
