Steel tubular members are pivotal components in modern construction, offering a unique combination of strength, efficiency, and aesthetic appeal. Their inherent structural advantages, such as high stiffness-to-weight ratios and excellent resistance to torsional forces, have led to their widespread adoption across diverse engineering applications, from high-rise buildings and bridges to industrial structures and offshore platforms. The versatility of steel tubes, encompassing circular, square, and rectangular cross-sections, allows for tailored solutions to complex structural challenges. However, the performance of these members is intricately linked to several critical factors, including their seismic behavior, susceptibility to buckling, and durability under various environmental and loading conditions. Understanding these aspects is paramount for ensuring the safety, reliability, and longevity of steel structures. The seismic performance of steel tubular connections, specifically their ductility and energy dissipation capabilities, is a crucial area of investigation for designing resilient infrastructure in earthquake-prone regions. Geometric parameters and welding details significantly influence the overall structural integrity under cyclic loading, providing vital data for safer designs [1].
