D. Zhi, Auteur ; G. B. Nie, Auteur ; F. Fan, Auteur Année de publication : 2013 Article en page(s) : pp. 1505–1514 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Single-layer reticulated dome Earthquake Vulnerability Risk assessment Damage state Résumé : In order to provide a good understanding of the damage states of single-layer reticulated domes under earthquake loading, a number of increment dynamic analyses are carried out on domes with different spans, rise-span ratios, roof weights, and other parameters. A model is proposed for the quantitative evaluation of damage. The damage states for single-layer reticulated domes are defined based on their structural dynamic performance and corresponding damage factors. The vulnerability of single-layer reticulated domes is shown using fragility curves with different damage states. A model of probability distribution for seismic hazard, structural damage probability, and various losses, including direct and indirect economic loss and maimed and fatality loss, is discussed for assessing risk. The risk assessment of a single-layer reticulated dome is performed for different seismic intensities for its loss or fatality acceptability.
