Fire Resistance of Reinforced Concrete Columns: Experimental Studies

The results of fire tests on seven columns, constructed at the Tianjin Fire Research Institute and tested at the National Fire Laboratory of the Institute for Research in Construction, National Research Council of Canada are described. The tests were carried out mainly for the purpose of providing data for the verification of methods for the calculation of the fire resistance of reinforced concrete columns, made with materials commonly used in China. The columns were made with siliceous and carbonate aggregates. The study variables included column length, dimensions of cross sections and load eccentricity.Les r\ue9sultats d?essais de r\ue9action au feu men\ue9s, au Laboratoire national de l?incendie de l?Institut de recherche en construction du CNRC, sur sept (7) poteaux fabriqu\ue9s au Tianjin Fire Research Institute sont d\ue9crits dans ces pages. Essentiellement, ces essais ont \ue9t\ue9 r\ue9alis\ue9s dans le but de g\ue9n\ue9rer des donn\ue9es aux fins de la v\ue9rification de m\ue9thodes pour le calcul de la r\ue9sistance au feu de poteaux en b\ue9ton arm\ue9 ou renforc\ue9 fabriqu\ue9s avec des mat\ue9riaux couramment utilis\ue9s en Chine, soit des granulats siliceux et carbonat\ue9s. Les variables \ue0 l?\ue9tude comprenaient la longueur des poteaux, les dimensions de leurs coupes ainsi que l?excentricit\ue9 des charges.Peer reviewed: NoNRC publication: Ye
