Analysis of Hollow Section “Y” Connections with the Application of Non-Linear Material Modeling

The use of welded structural hollow sections in civil engineering is relatively new. Design connections steel structures with requires a more specified approach, compared to traditional achieved gusset plates. Stress and local deformations at the connection area are non-linear very complex. This paper presents application numerical analysis for determination ultimate bearing capacity “Y” connections. In analysis, material model was applied. order validate applied method modelling, comparative analytically numerically determined experimentally obtained results has been conducted.
