Study of Irregular Shear Wall in Reinforced Concrete Structures - A Review

Urbanization has been lead to housing troubles. This has resulted in the rise of several Multi-storied and high rise buildings. Hence Structural Dynamics study has been steadily increasing over the years. The modern trend is towards tall and slender structures which have been designed as irregular due to innovative and architectural aspect. These buildings are affected by environmental factors like wind, earthquake and waterways. Millions of people world-wide annually die due to earthquakes which are responsible for billions of rupees of property damage. This has necessitated the study of Earthquake Engineering. However, study and research in the field of Irregular Buildings under seismic conditions is gaining momentum. The provision of shear wall in building has been found effective and economical. Shear walls are structural members used for providing strength of RCC (Reinforced Cement Concrete) structures against seismic load. Their very high in-plane stiffness and strength makes them ideally best for using in tall structure. They act as vertical cantilevers in the form of separate planer wall. In this paper, the behavior of the structures with and without shear wall has been studied having different types of vertical irregularities. This study concludes the research has been required to get economical & efficient lateral stiffness system for high seismic prone areas. Also for optimization & design of high rise building with different structural framing systems subjected to seismic loads and to improve the understanding of the seismic behavior of building structures with vertical irregularities.
