Abstract

Concrete Filled Tube (CFT) steel columns have become increasingly popular in recent years due to their many advantages in industrial and high-rise buildings, bridges, piers and piles. These columns often run in circular shapes. The main reason for this is that circular sections create more confinement than other sections in core concrete. This caused the circular sections to be used more frequently in the CFT columns than other sections. But sometimes it will be impossible to use circular sections and will have to use special forms, such as square and mesial sections, and L and T-shaped sections in some parts of the building. Due to the importance of this issue in this paper, we tried to introduce and investigate the mechanical behavior of CFT columns with T-shaped geometrical cross section and to investigate the parametric effect of steel wall thickness, and concrete compressive stress, on the mechanical capacity and behavior of these columns. Finally, after conducting the research, it was found that in CFT columns with T-geometrical cross section, between the effect of steel wall thickness and the type of concrete, the steel wall thickness parameter is the most influential parameter on the bearing capacity of the CFT columns, and also between the steel wall thickness parameter and the cross section height, Influence of elevation changes on ductility, hardness, and bearing capacity of the cross section It is greater than the thickness of the steel wall.
