Abstract

Reinforced cement concrete is a highly versatile and widely used construction material, essential for its ability to enhance tensile strength through the incorporation of twisted steel bars of varying diameters. Structural hollow steel sections, when filled with concrete, offer numerous advantages, such as increased load-carrying capacity and reduced sectional dimensions, leading to more slender and efficient members. These sections eliminate the need for formwork during casting and installation, reducing labor and cost as they do not require reinforcement fabrication. Additionally, while concrete is protected from fire hazards by being encased in steel, the steel itself is prone to corrosion; however, this can be mitigated with appropriate anti-rust or anti-corrosive coatings. Precast elements have become increasingly popular in modern construction, particularly in housing, and are valuable for repairs and retrofitting in cases of structural damage due to natural disasters or the need for rehabilitating old structures. This project focuses on confining concrete within hollow steel tubes, enhancing the elements' load-carrying capacity, flexural stiffness, and rigidity. These concrete-filled tubes are then evaluated against hollow tubes of the same dimensions, comparing their flexural and compressive strengths through finite element analysis and corresponding graphical representations.
