5. Data processing. Results

The results obtained during the bridge test were interpreted and compared with the model
calculation values according to the methodology described by the standards.
The report between the ratio of the measured elastic deformation (f el ) and the calculated
ones (f teor ) (“Fig. 25”) were corresponding to the criterion of similitude, the maximum values Ef f
stat in the middle of the span, the design characteristic loads being compared to the testing loads.
