Abstract :

This paper is the brief account of the research conducted in the recent past related to the different structural irregularities. The plan related and vertical irregularities have been covered. The norms described by the numerous structural codes viz. IS18932 have been highlighted in short. It has been seen that the code identifies the almost same limits for the Plan and vertical irregularities. The variety of structural modelling has been described briefly. On the basis of the review of the work related to plan irregularities it can be stated that multi-storeyed buildings are more safe as compared with single storeyed structures. The idea of balanced Centre strength (CV) and Centre Rigidity(CR) location can very well improve the seismic response of the structure. It is also seen that strength Vertical Irregularity has the utmost effect on the seismic behaviour and minimum effect due to mass irregularity. Dynamic Analysis is more effective accurate in studying the seismic behaviour due to different irregularities.
