Abstract
<p>Vertically irregular buildings are frequently constructed all over the world for both functional and aesthetic reasons. However, post-earthquake fact-finding survey studies reported that buildings with vertical irregularities were extremely seismically vulnerable. As a result, it is critical to investigate the causes of their high seismic vulnerability in order to enhance their performance. The vertical irregularities in the buildings are caused by asymmetric distributions of mass, stiffness, and strength. These irregularities in the structures results in the floor rotations (torsional response) in addition to floor translations. In this study, the seismic behaviour of vertical irregular buildings located in different seismic zones of India are assessed. The vertical irregular building configurations such as step back, set back, step back-set back, and split foundation are considered in this study. The analysis is performed using finite element software. From the study, it is observed that the performance of vertically irregular building is different in different seismic zones.</p><p>Keywords: Include a list of not more than 10 keywords, for example: post-tensioning; anchors; slabs; walls; high-rise buildings.</p>
