| Abstrait: |
I-girders of steel concrete composite bridges should be verified against Lateral Torsional Buckling (LTB) under traffic loads next to the intermediate supports. This paper introduces to the different methods of Eurocode 3 part 2 (steel bridges) to verify LTB and applies them to an example of typical twin-girder bridge. It shows that Eurocode 3 is very severe in comparison to the previous European National Standards and in comparison to a second order linear elastic analysis. The main reason of this conservative aspect is the use of the European buckling curve d. |
