| Abstract: | Based on the energy approach,this paper presents a numerical method to predict the critical moment of simply supported thin-walled beams containing web openings,subject to point loads at midspan.Used the universal FEM program ANSYS,a total of 30 I-section beams have been analyzed.The comparison between the results shows that this method is available. |
| Keywords: | Thin-walled beams containing openings Flexural-torsional buckling |
