Sommario

Nel presente articolo si espone un possibile metodo per studiare la sicurezza di organismi strutturali esposti all'azione di più terremoti susseguenti.

Viene sottolineata l'opportunità di analizzare il comportamento della struttura sotto il terremoto decisivo, e si dimostra con un esempio la possibilità di calcolarne l'affidabilità mediante l'indagine del modo di collasso.

I risultati numerici mostrano che questo criterio fornisce, almeno nel semplice caso esaminato, conclusioni coerenti non la pratica tecnica, benché di solito le Norme antisismiche non tengano conto esplicitamente del fenomeno della accumulazione del danno.

Summary

This paper presents an approach to investigate seismic reliability of structures acted on by more earthquakes.

The opportunity to analyze the behaviour of structures under the decisive quake is stressed, and the possibility to derive safety statements by inspecting the way the structure collapses is proved with regard to a simple structural pattern.

Numerical results show that the criterion yields results quite consistent with usual practice, though, usually, cumulation of damage is not explicitly accounted for in aseismic standards.
