| Summary: |
| Profiled sheets are widely used in modern steel structures, either as cladding
or as casing in composite structures. Their strength calculation is a complex task because
of their complicated cross-section shape. Manufacturer’s catalogues provide data about
their strength, often for continious surface load, but rarely for patch loads. In this
research, the Finite Element Method (FEM) analysis with geometrical and material
nonlinearity and contact analysis in the support zones was applied for the strength
calculation of one typical profiled steel sheet. The analysis encompassed several patch
load patterns. Results of the research showed that such elements can withstand relatively
high localized loads, and that ultimate load depends much on the patch load position in
transversal direction. |
