NUMERICAL ANALYSIS OF SQUARE HOLLOW COLUMN-BEAM CONNECTIONS BY ABAQUS
Abstract
In recent years, steel or composite beam-column connections have drawn increasing praise due to the rapid development of assembled steel structures. However, limited researches have paid attention to the analytical behavior of square hollow column-beam joints. This work presents a numerical study on the static and cyclic behavior of the connections between a square hollow steel column and I-beam. Finite element analytical modeling of the joint was performed considering complex contact interactions and material models. Six different connections were evaluated by using ABAQUS. The modeling techniques used in this work, including the mesh and element types, the material properties, and the contact elements, were validated by comparing the numerical results of a through plate connection model with the experimental study results. Good agreement between the test and analytical results was observed in terms of the failure modes and the hysteretic behavior. Based on numerical results, the failure mode, moment-rotation curves for the SHS column to steel beam connections were discussed.
