Abstract

The effects of vertical irregularities on the response of a structure cannot be underestimated. The presence of vertical irregularities will change the overall response of a structure. In this study effects of different types of vertical irregularities on seismic response and seismic vulnerability of a structure have been analyzed. A six-story reinforced cement concrete building is used as a benchmark building and 28 new models are made by incorporating vertical irregularities in the benchmark model for analysis. The response of all the models is analyzed by using the pushover analysis. SPO2FRAG software is used for the assessment of the seismic vulnerability of models. From the analysis results, it is observed the change in stiffness, mass and position of irregularities in a structure will have a significant effect on the overall response of a structure. The results of the study are presented in terms of story displacements, inter story-drift ratios, capacity curves and median capacity plots.
