Hybrid Fire Testing for Performance Evaluation of Structures in Fire - Part 2: Application

Abstract

A hybrid fire testing (HFT) approach was carried out by means of both computer simulation and experimentation using the National Research Council Canada?s (NRC) testing facilities in Ottawa. Fire structural performance of a 3D full-scale 6-storey building structure was tested for a fire compartment scenario in the main floor of the building. The column in the designated fire compartment was exposed to the fire in a column furnace and the rest of the building was simulated using a numerical modeling. The methodology of the HFT and its numerical verifications were developed and described in a previous report. This report includes application of the HFT and its displacement results for fire structural performance of the whole 6-storey building. It also includes results of a separate column tested in fire using the traditional fire resistance standard test method. The second column specimen was identical to that of the column tested using the HFT. A comparison is provided between the results of the standard test and the HFT.Une d\ue9marche d?essai de r\ue9sistance au feu hybride (ERFH) a \ue9t\ue9 r\ue9alis\ue9e, par simulation par ordinateur et parall\ue8lement par exp\ue9rimentation aux installations d?essai du Conseil national de recherches du Canada (CNRC), \ue0 Ottawa. La performance structurale au feu d?une structure de b\ue2timent de six (6) \ue9tages en vraie grandeur en 3 dimensions (3D) a \ue9t\ue9 mise \ue0 l?essai pour un sc\ue9nario d?incendie en compartiment \ue0 l?\ue9preuve du feu, au niveau principal du b\ue2timent. La colonne dans le compartiment \ue0 l?\ue9preuve du feu d\ue9sign\ue9 a \ue9t\ue9 expos\ue9e au feu dans un four \ue0 colonnes, et le reste du b\ue2timent a \ue9t\ue9 simul\ue9 par mod\ue9lisation num\ue9rique. La m\ue9thodologie de l?ERFH et ses v\ue9rifications num\ue9riques ont \ue9t\ue9 mises au point et d\ue9crites dans un rapport ant\ue9rieur. Ce rapport comprend l?application de l?ERFH et ses r\ue9sultats li\ue9s au d\ue9placement pour ce qui est de la performance structurale au feu du b\ue2timent en entier. Il comprend \ue9galement les r\ue9sultats d?un essai de tenue au feu men\ue9 sur une colonne s\ue9par\ue9e au moyen de la m\ue9thode d?essai de r\ue9sistance au feu traditionnelle standard. Le deuxi\ue8me sp\ue9cimen de colonne \ue9tait identique \ue0 celui de la colonne mise \ue0 l?essai selon l?ERFH. Enfin, on \ue9tablit une comparaison entre les r\ue9sultats de l?essai standard et ceux de l?ERFH.Peer reviewed: NoNRC publication: Ye
