ABSTRACT
Research activities aiming at understanding selected items of steel joints behavior in the persistent and accidental situation has been conducted at Rzeszow University of Technology. The following subjects were considered: the behavior of beam splices of beams in large size steel industrial structures and especially the assessment of safety to use the component method of EN 1993-1-8 to design such joints; the role of joints in assurance survival of steel-framed structures subjected to accidental loading, especially influence of joints geometrical and material properties on their behavior in column loss scenario; estimation of actual values of available rotation capacity of selected steel joints, to be used in robustness analysis of steel frames. An investigation was provided by experimental tests of bolted end-plate joints, advanced FEA with the use of validated models, and wide parametric studies. Results of the above-mentioned researches can find application in design practice.
