In recent past years, serious damages and causalities due to these disastrous forces have been visualized and various lessons have been learned mainly by the designing and construction authorities. In the present study, the effect of vertical irregularity in a building is studied with the help of different analysis methods. Linear elastic analysis, nonlinear static pushover analysis, and linear dynamic response spectrum analysis are applied on structures with one or more vertical irregularity incorporated in it so as to study the individual as well as the combined effect of these irregularities. The incorporated irregularities are as per IS1893 Part-1:2002. The results obtained are discussed under the following headings such as displacement values, mode shapes, modal time period, modal mass participation factor, base shear performance point capacity of structure and hinge formation pattern are compared and studied for various irregularities in structure with and without infill walls. All comparisons are represented graphically and also in tabulated form in terms of percentage variation wherever required.Articlehttp://www.tjprc.org/publishpapers/2-11-1531890392-2.IJCSEIERDAUG20182.pdf
