 note = {10th Conference "Shell Structures: Theory and Applications", October 16-18, 2013 in Gdansk, Poland., It is known that flange vertical buckling arises in a steel girder having very weak web plate, and it is generally believed that vertical buckling does not occur in a steel girder with “normal” section dimensions. However, in the author’s experimental test, unexpected vertical buckling was observed. In this paper, a series of numerical analysis is made on flange vertical buckling of hybrid steel girders, and the limit web width-thickness ratio and so on are studied. The results indicate that the web width-thickness ratio has small contribution to the vertical buckling behaviour., Article, Shell Structures: Theory and Application. 3:445-448 (2013)},
