| | Summary: |
| | The reinforced concrete 30m long folded plate structure is designed on the
basis of internal forces calculated by finite strip method assuming a linear behavior of
the structure. The curve of fracture of characteristic cross-sections is shown on
diagrams of interaction, which are drawn for working diagrams of concrete and steel
according to Eurocode 2 and rheological-dynamical analogy. By successive increase of
load, using the harmonic coupled finite strip method, the load at which the fracture of
characteristic cross sections occurs is determined. Comparison of global safety factors
of characteristic cross-sections obtained by the linear and geometric nonlinear analysis
shows that, in most cases, the linear analysis gives results on the safe side compared to
the results of the analysis based on the assumption of geometric nonlinear structural
behavior. However, this conclusion can not be generalized because failure of some
cross-sections of such dimensioned structure, according to nonlinear analysis, occurs
under load that is only 30% higher than the service load. |
