Abstract

The principle objective of this paper is to study the structural behavior of High-Rise RC structure for different plan configurations, such as rectangular building along with Plus, C, L, and H-shape in accordance with the seismic provisions suggested in IS: 1893-2002 using ETABS. The analysis involves load calculation manually and analyzing the whole structure on the ETABS 9.7.1 version for dynamic analysis, i.e. Response Spectrum Analysis and 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. Analysis is carried out for seismic zone IV by taking medium soil condition. After the analysis, various responses like maximum storey displacement, maximum storey drift, storey shear, and maximum overturning moment are plotted so as to match the results of the linear and non-linear dynamic analysis.
