Component based finite element design of steel joints

Popis výsledku v původním jazyce

This paper describes the principles of multi-level Finite Element modelling for design of structural steel joints. The integral part of the design by Finite Elements is the Validation and Verification of the model and its results. For models by shell and solid elements it is mesh sensitivity study. In component bases finite element method (CBFEM), the steel plates are considered by materially nonlinear analysis (MNA). Their resistance in plastic stage is limited by strains. The behaviour of components, e.g. of bolts, anchor bolts, welds etc., is treated by introducing nonlinear springs representing its behaviour in terms of initial stiffness, ultimate resistance and deformation capacity. To show this process a contribution is prepared, which summarises the history of achievements of Finite Element Analyses (FEA) in structural steel joints. This paper shows differences between the research-oriented and design-oriented models and the current trends in modelling of connection components. Both have their roles in advanced analyses. The Validation & Verification is demonstrated on model of block shear during potential failure mode for gusset plate connection and for the base plates loaded by bending moments around both axes. The summary shows the potential in design of elements including their joints.
