Valutazione degli spettri di piano per la progettazione sismica di elementi non strutturali (2015)
Type of ContentJournal Article
The main results coming from a work presented at the Second International Workshop on Seismic Performance of Non-structural Elements (SPONSE) (Pavia, may 2015), focused on the prediction of acceleration demands on secondary structural and non-structural elements at different levels of a building, are summarized in this paper. The seismic input for non-structural or secondary elements at different floor levels of a building is evaluated, in the modern seismic codes, through simplified methods. Although the use of simple analyses should be advocated in these cases, damage to both secondary structural and non-structural elements in recent earthquakes have highlighted that the current methods may result in wrong estimations. For this reason, an improved design procedure for such elements is needed, in order to take a step towards the formation of accurate but simplified methods of predicting floor spectra. The results of non-linear time-history analyses of a series of multi-degree of freedom supporting structures indicate that the new methodology is valuable.
