Design of hybrid beam-to-column joints between RHS tubular columns and I-section beams

This paper presents the proposal of a framework and operational proposal for the inclusion of hybrid joints between tubular columns and open section beams in EC3-1-8, providing a design specification for the most common types of joint typologies and allowing for the evaluation of their stiffness and resistance. The code conform specification further characterizes the equivalent cross-section component model for the tube zone that contributes to the joint behaviour, including the out-of-plane deformation of the column faces.
