| Summary: |
| Two reinforced concrete folded plate structures of span length 20 and 30m
are designed according to internal forces calculated using linear finite strip method.
Diagrams of interaction with curves of fracture are drawn for selected characteristic
cross-sections, using working diagrams of concrete and reinforcement according to
Eurocode 2 and rheological-dynamical analogy. The ultimate load, at which the fracture
of characteristic cross-sections occurs, is determined by successive increase of load
through the geometric nonlinear analysis of structures using harmonic coupled finite
strip method. Comparing the safety factors calculated from the results of linear and
geometric nonlinear analysis, the conclusion about the rational method of analysis,
regarding to the length of structure, is made. |
