Prediction of Sheeting Failure by the Theory of Fictitious Elastic Strain at Failure

Popis výsledku v původním jazyce

First-generation sheeting may fail if loaded by combined bending moment and concentrated load. Due to the concentrated load the imperfection of the plate can increase rapidly, this imperfection can be predicted by an existing method. In this paper the post-buckling strength of uniformly loaded square simply supported thin plates with sinusoidal shaped initial imperfections and longitudinal edges free to wave in plane is discussed. To predict the elastic post-buckling behaviour of plates a large-deflection solution is proposed. Determining the post-buckling strength as the elastic load corresponding to first membrane yield gives very conservative results for some plates. More accurate strength prediction is obtained by using empirical expressions for afictitious elastic strain at failure. The new prediction method is compared with Eurocode3 and Marguerre?s solution on experimentally tested sheetings.
