dc.description.abstractComparison of Effective width method and Reduced stress method is performed based on design procedures given in NS EN 1993-1-5The two methods lead to exactly equal critical buckling stress and strength for uniaxially loaded plates and no significant difference is observed between hand calculated results and results of the numerical analysis.Analysis of biaxially loaded plates showed that results of Reduced stress method and that of finite element analysis are very close for square plates, but not for rectangular plates. Reduced stress method gives 10 % - 20 % lower buckling stress and 6 % - 14 % lower strength values compared with results from finite element analysis.Hand calculations show that both methods lead to equal critical buckling stress for stiffened plates. But Reduced stress method gives a very conservative strength results. It was found to be about 10 % difference between the two methods when applied on relatively narrow and long stiffened plates. Strength results based on Effective width method for stiffened plates are generally lower than results of numerical analysis. The difference is especially very large for both short and wide plates, since effect of column-like buckling is taken into consideration. Hence the interpolation equation used in the design process is not good enough to capture the real behavior of such stiffened platesnb_NO
