Seismic Effect of Regular and Irregular RC Building with and Without Infill Frames using ETABS

Abstract

This work is on the seismic behaviour of regular and irregular RC buildings with and without infill frames. It's below stood that buildings that are regular in plan (regular building) perform far better than those which have irregularity in plan (irregular building) under seismic loading. Irregularities don't seem to be avoidable in construction of buildings. This method of analysis is projected in terms of equivalant statics, responce spectrum and pushover analysis consistant with IS 1893:2002(part 1) code. Results of those analyses are mentioned in terms of the bottom construction drift and storey stiffness. From these results it's finished that laterel displacement and construction drift are going to be a lot of in vacant frame compare with the infill frames, whereas the bottom shear are going to be less in normal frame compare with the infill frames. It is also observed that lateral displacement and story drifts are more in irreguler buildings than reguler buildings.
