Abstract
AbstractIrregular systems make up a significant portion of urban infrastructure. As a result, irregular structures, especially those in seismic zones, become a matter of concern. Buildings with irregular shapes are more likely to be designed than buildings with regular shapes, as the architectural element of a building has become more important than the structural safety of the building in recent years. According to studies, irregularity plays a significant role in seismic behaviour, forcing a comprehensive investigation in structural design. The present research addresses the study and behaviour of structures with composite columns–concrete-filled steel tube columns (CFST) having irregularities in plan and elevation, subjected to ground motion. In this paper, a study on how composite column–concrete-filled steel column meets seismic demands in five irregular structures and its advantages over RCC has been carried out by pushover analysis in ETABS.KeywordsCFST columnsIrregular buildingsPushover analysisSeismic
