49. Un’analisi di sensibilità
DATI IN INGRESSO:
• Localizzazione dei 130 punti in cui
valutare il collasso.
• Momenti flettenti MGX, MGY e
torcenti MGXY indotti dai carichi
statici.

51. Sistema di monitoraggio
NOTE
Da gennaio 2004 sono monitorate le pressioni, le accelerazioni, la velocità del vento, gli sforzi nei cavi, etc. in diversi punti significativi
della copertura. Saranno condotte a breve prove per la caratterizzazione dello smorzamento.

52. Un sistema dissipativo aggiunto
NOTE
Parte reale e parte immaginaria dell’autovettore del 1° modo complesso, ricostruita per combinazione dei modi reali non smorzati
considerati.
f1=0,28 Hz - ξ1=3,7%.

53. Un sistema dissipativo aggiunto
NOTE
L’efficienza del sistema dissipativo è stata testata anche sotto l’azione del vento (pressione RWDI dir. 270°). Si dimezza la risposta strutturale
rispetto al caso ξintinseco=1% e comunque rende accettabili le vibrazioni anche per ξintinseco<1%.
