Progressive collapse of the world trade center / K. A. Seffen in Journal of engineering mechanics, Vol. 134 N°2 (Fevrier 2008) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 134 N°2 (Fevrier 2008) . - pp.125–132. Titre : Progressive collapse of the world trade center : Simple analysis Type de document : texte imprimé Auteurs : K. A. Seffen, Auteur Année de publication : 2008 Article en page(s) : pp.125–132. Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Progressive  failure  Collapse  Residual  strength  Dynamic  analysis  Buildings  high-rise  New  York  New  York  City  Terrorism Résumé : The collapse behavior of the World Trade Center towers is considered formally as a propagating instability phenomenon. The application of associated concepts enables the residual capacities of both towers after the onset of collapse to be formally estimated. This information is combined into a simplified variable-mass collapse model of the overall dynamical behavior. The resulting, nonlinear governing equation of motion can be solved in closed form, to yield compact information about the overall collapse conditions.
