Mechanically Consistent Scaling of Composite Beam-Column Joints
Today, mature beam-column joints exist for steel-concrete composite structures and their structural behaviour has been studied in many tests. Finite Elements can be used to study such regions in detail but are impractical for the analysis of a complete frame. This paper presents a scaling method that allows for the transfer of local behaviour to a higher scale analysis and back using orthogonal boundary states of a macro region as input to an FE model. To exemplify this scaling process, a sophisticated local FE model for a composite beam-column joint with welded connections is used to derive the macro constitutive law of a plane rectangular macro element, which is then applied in the analysis of a 2-storey 2-bay frame under horizontal loading. The extension to cyclic loading is discussed and so are the implications for practical frame analysis in the future.
