Polygonal hollow section tubes such as dodecagonal, oval, square, and hexagonal tubes offer a number of advantages over conventional circular and rectangular tubes. They can be used for a variety of engineering and architectural applications due to its distinctive geometry, which offers various structural qualities and aesthetic appeal. Hollow sectional tubes are widely employed in a wide range of structural applications due to their high strength-to-weight ratio and structural efficiency. This study investigates the strengthening of hollow sectional tubes under tensile loading that are square, dodecagonal (twelve-sided), oval, and hexagonal (six-sided) using finite element analysis (FEA). The purpose of the study is to determine how strengthening methods impact the plastic deformation and failure processes of these tubes. Applying a load that exceeds the elastic limit of the tube wall causes plastic deformation, which permanently alters the material. Analytical analysis was done on the failure processes, load-displacement curves, and load-carrying capacities of hollow section tubes under strengthening strategy. In addition, it studies the behaviour and performance of hexagonal, oval, dodecagonal, and square-shaped hollow sectional tubes with ring and vertical stiffeners. By changing the depth of the stiffener, for instance, the effectiveness of these tubes was investigated in more detail. In order to create and improve hollow sectional tubes for a varietyof structural purposes, the study's findings provide significant new knowledge that will lead to safer and more efficient building techniques.
