DESIGN OF UNIFORMLY COMPRESSED STIFFENED PLATES A review of Eurocode 3-1-5

摘要

The design of longitudinally stiffened plates is on the agenda in connection with the conversion of Eurocode 3 to EN. There are several open questions of which the effective area of a longitudinally stiffened plate under uniform compression is studied in this paper. The method is performing a parametric FE study in order to overcome the lack of systematic experimental data. A calibration of the FE model against experimental date is done to check its predicting power. The result is that the model is correct within 10% and the parametric study shows an unexpected variation of the resistance with the length of the plate.
