Test-calculation comparison: CAMUS I model, Nice 0.71 g signal
Figures 7.20, 7.21 and 7.22 show the calculation-test comparison of the front
displacement for an earthquake level that caused important damage to each model.
In each case, the non-linear plastic model is capable of estimating the overall
behavior of the structure quite well. At the local level, the digital results highlight
operating modes similar to the experimental modes - there lies the interest in such
modeling (Figure 7.23).
In the case of the CAMUS I model, the behavior is clearly influenced by a strong
localization of the strains at the level of the bar stoppers on the second floor, and by
the appearance of inclined cracks due to the shear force. Such behavior is quite
