ABSTRACT
This paper describes the behaviour and static strength of multiplanar connections between I-section beams and circular hollow section columns loaded with in-plane bending moments. Five different ratios between the bending moments on the in-plane and out-of-plane beams are investigated. A parameter investigation has been carried out which covers the most important geometrical parameters. Twentyfour multiplanar connections are analyzed using both geometrical and material non-linear finite element analyses. Analytical models are derived on the bases of the ring model approach. Based upon these models a parametric formula is created. The parameters in the formula are determined with regression analyses, using the finite element results. A reasonable agreement is found between the strength as predicted by the formula and the finite element results.
