Preliminary analysis on lateral-torsional buckling of stainless steel beams with slender cross sections

Popis výsledku v původním jazyce

Design of stainless steel members has been established mainly for hollow sections (CHS, SHS/RHS) as these are the typical stainless steel profiles. However, open sections are also being used in structures and the design rules for both local buckling of very slender sections as well as lateral torsional buckling curves are based on very limited experimental and numerical research. As far as the authors are aware, for the moment, experimental research is lacking for open sections subjected to local buckling and lateral-torsional buckling. Therefore, at the Czech Technical University in Prague, six stainless steel welded I sections were prepared for tests being used for a model validation. The tests use two stainless steel materials (austenitic and ferritic steel), one section slenderness (Class 4 web and flanges) and three beam slendernesses. The paper shows the details of the prepared tests. Besides a FE model in Abaqus software was prepared to design the tests, it was also used for a simple preliminary study showing the difference in behaviour of stainless steel beams subjected to global buckling.
