Comparative Study on Irregular RCC Frame Structure in Two Different Zones
Abstract
Irregularities in a structure are observed as the most important types of failures during seismic activities. A seismic activity causes utmost damage to a structure and the individuals residing in it depending on the Richter scale magnitude. It is necessary to analyse such structures before it hits the dangerous event. In this present study, a G+16 story RCC framed irregular building with torsional irregularity is analysed using ETABS software. Torsional irregularity, in this study is found by calculating the ratio of the maximum story drift to the average story drift which is obtained from the story response plots. This study has carried out the comparison between linear static analysis and response spectrum analysis on a G+16 story RC framed structure with irregularities in seismic zone III and seismic zone IV. The main objective of this study is to study the behaviour of the structure by determining different parameters such as storey response plots i.e., story displacements, story drifts, story shears etc. The analysis is carried out in JB Institute of Engineering and Technology on ETABS software at CAD laboratory, Moinabad, Hyderabad.
