Experimental Studies for Evaluating the Fire Endurance of High-Strength Concrete Columns

Experimental studies were carried out to determine the fire resistance performance of high-strength concrete columns. The results of fire endurance experiments on ten full-scale columns are described in this report. The test variables included concrete strength type of aggregate in concrete, silica fume, tie configuration and spacing, load intensity and eccentricity of loading. These studies were conducted as part of a collaborative research program, aimed at studying fire endurance of high-strength concrete columns.Des \ue9tudes exp\ue9rimentales ont \ue9t\ue9 r\ue9alis\ue9es dans le but de d\ue9terminer la performance en termes de r\ue9sistance au feu des colonnes en b\ue9ton \ue0 haute r\ue9sistance. Les r\ue9sultats des exp\ue9riences de tenue au feu men\ue9es sur dix (10) colonnes en grandeur r\ue9elle sont d\ue9crits dans ce rapport. Les variables des essais comprenaient la r\ue9sistance du b\ue9ton, le type de granulat contenu dans le b\ue9ton, les fum\ue9es de silice, la configuration et l'espacement des attaches, l'importance de la charge et l'excentricit\ue9 du chargement. Ces \ue9tudes ont \ue9t\ue9 men\ue9es dans le cadre d'un programme de recherche concert\ue9e portant sur la r\ue9sistance au feu des colonnes en b\ue9ton \ue0 haute r\ue9sistance.Peer reviewed: NoNRC publication: Ye
