ABSTRACT This paper describes the principles multi‐level joints and element design in steel structures. The system response quantity and application features of Component Based Finite Element Method (CBFEM) for design of eccentric gusset plate connection of a truss steel member. Research oriented finite element model (ROFEM) is validated on experiments. The models are analysed by geometrically and materially non‐linear analysis with imperfections (GMNIA). The ROFEM is compared with simplified CBFEM model which includes only the joint. The proper behaviour of components, e.g. of bolts, anchor bolts, welds etc., is treated by introducing components representing its behaviour in term of initial stiffness, ultimate resistance and deformation capacity. To show this process a contribution is prepared, which summarises the history of achievements of FEA application in structural connections. Contribution shows the current trends in advanced modelling of connection components and differences of the research oriented and design oriented FEA models. Both have their roles in advanced analyses. On the eccentric gusset plate connection of diagonal steel member is shown the coming models with coupling of element and its joint design.
