Distortional Lateral Buckling of Unstiffened Composite Bridge Girders
A finite element parametric study is reported of elastic distortional lateral buckling in laterally unstiffened fixed-ended composite girders with web depth/thickness ratios ranging from 39 to 100. The work is relevant to the design of highway viaducts with spans up to about 30m. It shows that there is much room for improvement in existing design methods, that further study is needed of the interaction between lateral buckling and inelastic local buckling, and that the latter is more likely to govern design.
