What is it about?

The numerical analyses in this paper quantify the relation of out-of-flatness magnitude, web and bottom flange slenderness, and yielding stress on first yield flexural moment on steel highway girders.

Why is it important?

It can show how much out-of-flatness in particular effects the first yield flexural moment. These data can be used to derive out-of-flatness limits and criteria.


This is a practical research that models actual steel highway girders having out-of-flatness compatible with first buckling mode shape. Real bridges were modeled in this research.
