From the last few decades, the use of concrete-filled steel tubular (CFST) columns has been very popular particularly in high rise buildings and high seismic zones. These columns have various advantages over normal conventional concrete columns. This paper focuses on the study of the performance of a multistory irregular building with CFST columns using ETABS software. In the present study, three buildings with plan dimensions 40x45m of G+12 stories, with earthquake zone-V and soil type medium were modelled with varying columns types. The design and analysis were carried out using equivalent static method and response spectrum method as per IS-1893 2016 on the ETABS software package. he total height of the building was taken as 42m with the height of each floor as 3.5m. The conclusion was made after studying parameters like Base Shear, Max. story displacement, Max. storey drift, Total Dead load of the structure, Max. time period, and Storey Shear. All the building models meet the allowable limit for safe design. It was concluded that the building with CFST columns has better resistance at high seismic zones and the cross-sectional dimensions required by building with CFST columns to pass the design check are lesser than the other types of columns.
