SEISMIC BEHAVIOR OF HIGH RISE R C BUILDING IN DIFFERENT ZONES

When a structure is subjected to earthquake, it responds by vibrating. An earthquake force can be resolved into three mutually perpendicular directions-the two horizontal directions (x and y) and the vertical direction (z). This motion causes the structure to vibrate or shake in all three directions; the predominant direction of shaking is horizontal. It is very essential to consider the effects of lateral loads induced from wind and earthquakes in the analysis of RCC structures, especially for high-rise buildings. The present study is limited to RC multi-storied commercial building in different zones I, II, III & IV .The analysis is carried out the help of FEM software's ETABS. The building model in the study has 21 storeys with constant storey height of 3m. Four models are used to analyze with equal bay lengths and the number of Bays and the bay-width along two horizontal directions are kept constant in each model for conveni- ence. Different values of ZONE FACTOR are taken and their corresponding effects are interpreted in the results.
