ANALYSIS OF OPTIMUM POSITIONING WITH AND WITHOUT SHEAR WALL FOR A DIFFERENT ZONE BY USING E-TAB

High Rise RC Structure subjected to most dangerous earthquakes. It was found that main reason for failure of RC building is irregular distributions of mass, stiffness and strength or due to irregular geometrical configurations. In reality, many existing buildings contain irregularity due to functional and aesthetic requirements. However, past earthquake records show the poor seismic performance of these structure. This is due to ignorance of the irregularity aspect in formulating the seismic design methodologies by the seismic codes (IS 1893:2002, UBC 1997, NBCC 2005 etc.). The review of seismic design codes and reported research studies show that the irregularity has been quantified in terms of magnitude ignoring the effect of location of irregularity. The principle objective of this project is to study the structural behaviour of High-Rise RC Structure for different plan configuration such as rectangular building along with L- shape and C- shape in accordance with the seismic provisions suggested in IS: 1893-2002 using ETABS. The analysis involves load calculation manually and analysing the whole structure on the ETABS 9.7.1 version for dynamic analysis i.e. Response Spectrum Analysis & Time History Analysis confirming to Indian Standard Code of Practice. For time history analysis past earthquake ground motion record is taken to study response of all the structures. These analyses are carried out by considering different seismic zones (III, IV and V) and for each zone the behaviour is assessed by taking medium soil. Post analysis of the structure, different response like maximum storey displacement, maximum storey drift, storey shear and maximum overturning moment are plotted in order to compare the results of the linear and non-linear dynamic analysis.
