Abstract :

Earthquake is a major concern in high seismic areas. Reinforced concrete multi storey buildings are subjected to most dangerous earthquakes. It was found that main reason for failure of RC building is, irregularity in its plan dimension and its lateral force resisting system. The structure which lies in seismic zones is to be specially designed. In this paper an analytical study is made to find response of different regular and irregular structures located in severe zone. Analysis has been made by taking 10 storey building by static and dynamic methods using ETABS. The factors which influence the earthquake resistance in a structure is shear wall, strong column, base isolation and use of dampers. The effects of torsion on buildings are investigated for both symmetric and asymmetric building. Study also shows that there is increase in shear, in columns and the columns at outer frame need some special attention for both the structure, especially for asymmetric building .The results showed that it was important to select a suitable criteria for asymmetric building rather than symmetric building and displacement was also found to be more for asymmetric type of building
