Generic Finite Element Model for Mechanically Consistent Scaling of Composite Beam-Column Joint with Welded Connection
A generic finite element model for composite beam-column joints with welded connections has been developed using current state-of-the-art local modeling. Using mechanically consistent scaling, it provides the constitutive relationship for a plane rectangular macro element with beam-type boundaries that can be used in high-accuracy frame analysis. Global geometric variables allow the generation of specific FE models for each instance of a joint. Using assumptions typical for most composite frames, the constitutive relationship of the macro element can be represented by bilinear laws for the macro bending and shear states which are then coupled by a two-surface law with yield and failure surfaces. This is demonstrated in an example.
