Název v původním jazyce

Lateral torsional buckling of Class 4 section uniform and tapered beams at elevated temperature

Popis výsledku v původním jazyce

An extensive numerical study of Class 4 section beams at elevated temperature is described in the paper. The study focuses on welded I-section beams of slender web and flange and covers beams of constant height as well as beams with significant taper ratio. For the model validation, three beam tests at elevated temperature were carried out and used for the model validation. The tests are also described briefly. The numerical parametric study extended the results significantly in terms of various temperatures, section slenderness for flange and webs considering also combination of more stocky flanges with a slender web, various beam slenderness and moment distribution along the beam. Based on the numerically calculated resistances, a simple design rule was developed for both constant and tapered members. The proposed model is believed to be predicting the beam capacity accurately with formulas simple enough to be used and accepted by structural engineers.
