HIERARCHICAL VALIDATION OF FEM MODELS OF BOLTED JOINTS

The results of multistage hierarchical validation of the advanced FEM models
used to define rotation capacity of steel joints have been presented in the paper.
Validation process has been carried out for different models with various level
of complexity. Comparative analysis of the FEM models has been conducted
in relation to results of own laboratory tests. Developed methodology of formation
material characteristic was a base for further analysis of advanced models
of end plate beam-to- column connections of in the area of forecasting rotation
capacity of the joint and the whole M-Φ curve
