Ultimate load-bearing capacity of the corrugated floor sheet in railroad vehicles

摘要

The calculation of the stability of an element such as corrugated floor sheet is very complex, and it is best to make an experimental testing. Because of the variety of geometric parameters appearing in the car structure, the reliability of the experimental results is based on a large number of samples. That is why experiments of this kind are generally rare, and they have not been performed in Yugoslavia. The standard material used for corrugated floor sheet (RSt37-2) was difficult to acquire, and it was necessary to replace it with some other material (RSt13). To accomplish this, an experiment was set up by which it was possible to establish the ultimate load capacity; that is, to verify the appropriateness of the substitution.
