Fire resistance tests of square hollow steel columns filled with reinforced concrete

The results of fire resistance tests conducted at the National Research Council of Canada, on three square bar-reinforced concrete filled steel columns, made by the Technical Research Centre of Finland are described. They were constructed with Finnish siliceous aggregate concrete. One of the columns was tested under a concentric load. The other two columns, which were similar, were tested under two different eccentric loads for the purpose of obtaining information on the influence of eccentric loads on the fire resistance of the columns.Sont d\ue9crits ici les r\ue9sultats d?essais de r\ue9sistance au feu r\ue9alis\ue9s au Conseil national de recherches du Canada sur trois (3) poteaux d?acier creux remplis de b\ue9ton arm\ue9, de section carr\ue9e. Ces poteaux ont \ue9t\ue9 fabriqu\ue9s par le Technical Research Centre of Finland, \ue0 partir de b\ue9ton contenant du granulat siliceux d?origine finlandaise. L?un de ces poteaux a \ue9t\ue9 test\ue9 sous charge concentrique. Les deux autres poteaux, qui \ue9taient semblables au premier, ont \ue9t\ue9 test\ue9s sous deux (2) charges excentriques diff\ue9rentes dans le but de g\ue9n\ue9rer des donn\ue9es sur l?incidence des charges excentriques sur la tenue au feu de ce type de poteau.Peer reviewed: NoNRC publication: Ye
