Component based finite element design of steel jointsThis paper describes the principles of multi-level finite element modelling for design of structural steel joints. The internal 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 is mesh sensitivity study. In component bases finite element design (CBFEB) are the steel plates considered by geometrically and materially non-linear analysis (GMNA). Its resistance in elastoplastic 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 term 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 connections. This paper shows differences of the research-oriented and design-oriented models and the currents trends in modelling of connection components. Both have their roles in advanced analyses. The validation and 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 to both axes. The summary shows the potential in design of elements including its connection.

The only way to prove correctness of simulated results by Finite Element Analyse (FEA) is through a methodical System response quantity process. Without this approval are the results of FEA meaningless and cannot be used in design process for making any decisions. The System response quantity consist of validation, which compares the numerical solution with the experimental data, of verification, which compares computational solutions with highly accurate analytical or numerical solution, and of benchmark cases, the examples for check of the software and its user on approved and simplified input and output. In the eighties FEA of structural connection was treated by some researchers as a non-scientific matter. Two decades later it was already a necessarily extension of experimental and analytical work. Today computational analysis, in particular computational mechanics and fluid dynamics, is commonly used as a catalyst of many research fields and an indispensable design tool. The recommendation for design by advanced modelling in structural steel is ready to be used in Chapter 5 and Annex C of EN 1993EN -1-5:2005. Development of modern general-purpose software and decreasing cost of computational resources facilitate this trend. The FEA of structural connection is the coming step in structural steel design. As the computational tools become more readily available and easier to use even by relatively inexperienced engineers the proper procedure should be employed when judging the results of computational analysis. This paper describes the System response quantity for Component Based Finite Element Model (CBFEM) which is a multilevel FEA method to analyse and design connections of steel structures, see [2]. The steel plates in connection are analysed in CBFEM procedure by FEA. The proper behaviour of components is treated by introducing a components representing well its behaviour in term of initial stiffness, ultimate resistance and deformation capacity, of bolts, welds etc. To help with this process is prepared a contribution, which summarises the history of achievements of FEA application in structural connections. Contribution shows the currents trends in advanced modelling of connection components and differences of the research oriented design oriented models. The particular attention is dedicated to design models of generally loaded endplates.

This paper describes the principles of multi-level Finite Element modeling 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 behavior of components, for example, of bolts, anchor bolts, welds etc., is treated by introducing nonlinear springs representing its behavior in terms of initial stiffness, ultimate resistance and deformation capacity. To show this process a contribution is prepared, which summarizes 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 modeling of connection components. Both have their roles in advanced analyses. The Validation and Verification are 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.
