dc.description.abstractThe concept of using a combination of suitable randomly distributed discrete fibers with nominal amount of lateral steel has been discussed in the literature to ease the requirement of high amount of confinement in the plastic hinge regions of high strength concrete (HSC) columns. However, the effect of high temperatures such as during fire, on the effectiveness of confinement, remains to be investigated. The objective of this study is to gain the knowledge of the strength and deformability of confined fiber reinforced high strength concrete after exposure to a thermal cycle at high temperature. Twenty one unconfined and sixty three confined cylindrical specimens of 150 mm in diameter and 450 mm in height and reinforced with 6 bars of 8mm Φ as longitudinal reinforcement and 6mm Φ hoops equally distributed along the height, were casted under this program. After exposing to the desired elevated temperatures ranging from room temperature to 800° C, the concrete specimens were allowed to cool down naturally in the furnace before testing them under axial compression the next day. The variables considered in this experimental study included different exposure temperatures, equally spaced lateral hoops and addition of steel and polypropylene fibers. The effects of temperature on confined fiber reinforced high strength concrete were studied and quantified with respect to strength and ductility gains. The test results show that the confined concrete performed better as compared to unconfined concrete both at room temperature as well as at elevated temperatures. Further, the residual strength and strain capacities of fiber concrete were better than the comparable non-fiber concrete.-
