Abstract

An innovative generation of fabricated columns has recently been developed by the research team at Monash University; however the challenging topic of connections between these columns and beams has not been investigated to date. This paper reports the results of a numerical finite element study on a robust modular beam to fabricated columns connections. A detailed finite element model is developed under monotonic loading using ABAQUS in which contact elements, damage to elements, and non-linearity in both material and geometry are considered. The initial stiffness, moment capacity, and rotation capacity of the proposed connection are extracted from the moment-rotation curves and compared with those of conventional connections, including extended end-plate, flush end-plate, and reverse channel connections, which are widely used for I-beams to rectangular hollow-section columns connections. It is demonstrated that this innovative beam-to-fabricated column connection benefits from the superior material properties of the column and shows more ductility, stiffness, and moment capacity than conventional connections.
