Study of Concrete Imperfections in T Shaped Multi-cell Composite Column

Orthogonal composite column is a structural element that consists of two or more individual columns arranged in a perpendicular fashion. This composite column is created by connecting the individual columns with a steel or concrete beam at their intersection. They are often used in high-rise buildings where they provide increased structural stability and load-bearing capacity. This analytical study focuses on investigating the effect of two common types of concrete imperfections, namely Interfacial gap and Cap gap, on the strength of T shaped multi-cell composite column. For this study, the preparing and analysing models of T shaped column without concrete imperfections is to be done and compared with column with imperfections and to study their behaviour. This paper aims to determine the impact of the concrete imperfections on the strength and failure patterns of T shaped composite column using ANSYS software. The results of this study provide valuable insights into the behaviour of T shaped multi-cell composite column with different types of concrete imperfections. The findings can be used to improve the design and construction practices of these structures and enhance their structural integrity and safety.
