Pilot Numerical Analysis of Resistance of Steel Beams under Combined Shear and Patch Loading

Popis výsledku v původním jazyce

The last decade revealed a growing interest in the use of computer models for the analysis of structural resistance. While some studies showed a good correspondence between experiments and FE models, missing widely accepted principles for creating FE models presents an obstacle for their practical applications. As a consequence, it is of interest to analyze the behaviour of steel beams based on computer modelling and compare the results with experiments. The application of FE models involves three basic steps: (i) development and unification of principles and parameters for FE models – the main focus of this study; (ii) evaluation of the accuracy of results based on comparison with experimental data – discussed briefly; (iii) determination of reliability parameters such as partial and sensitivity factors. The article presents an overview of the principles and main parameters for constructing FE models such as FE mesh size or material model, as well as analysis of their influence on resistance estimates, based on which recommendations for setting and parameter values of FE models for thin-web steel structures are provided.
