Dynamic Analysis of High Rise Rc Structure Using Etabs For Different Plan Configurations

Abstract

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. The case study in this paper mainly emphasizes on Dynamic Analysis of High Rise RC building for different plan configurations like Rectangular-shape along with L- shape and C- shape. The analysis involves load calculation manually and analyzing the whole structure on the ETABS 9.7.1 version for dynamic analysis confirming to Indian Standard Code of Practice. These analyses are carried out by considering seismic zones IV and the behavior is assessed by taking medium soil. Post analysis of the structure, maximum story displacement, maximum story drift, story shear and maximum overturning moment are computed and then compared for all the analyzed cases.
