Effect of chord length on CHS-RHS T-joints with slender sections

The chord length is an essential geometric property that must be defined in the analysis of isolated joints composed hollow steel sections, as well boundary conditions test. these parameters’ effect on behavior has been addressed by other studies, mostly with between circular sections compact or semi-compact cross-sections. Recent research about tubular cases slender where design containing still development. In this context, study aimed to evaluate T-joints section braces and rectangular chords through experimental tests a numerical considering application axial compression at braces. joint was examined load-strain load-deformation curves von Mises stress distribution, which allowed failure mode's determination resistance value. Chord face observed prototypes. It concluded minimum 0.6m would adequate value for properties used study, equivalent five times higher than width cross-section (5b0).
