The solutions are shown in graphs which may be used as design charts. From these graphs it can be seen that the optimal position of the stiffener is about 1/5 or 1/6 of the span for one or two stiffeners. The maximum obtainable increase of the buckling load depends of the proportion of the warping resistance to the torsional resistance. stiffener pair was inserted, and also when two stiffener pairs, spaced at 50 mm, were installed, shear buckling, Fig. 7, occurred, Figures 17 and Fig Initial buckling without interior stiffeners Fig Initial buckling with one interior stiffener ea.s. of the webFile Size: KB.

Buckling analysis of plates with stiffeners is a unique task for engineers. For this, EN ‑1‑5 provides three calculation methods: Effective Cross-Section Method, [1], Chapter 4‑7. Firstly the cross-section is categorized by means of table within the Eurocode. From the table buckling curve is found and then from the above table (Table within the code) imperfection factor $\alpha$ is taken to evaluate $(\ref{eq:buck_fi})$, $(\ref{eq:buck_chi})$.
