STRENGTH AND DUCTILITY OF FIBER-REINFORCED HIGH-STRENGTH CONCRETE COLUMNS

High-strength concrete has been used in many lower story columns of high-rise buildings, as well as low-rise and mid-rise buildings, bridges, and foundation piles. This study tested 21 high-strength, fiber-reinforced concrete columns consisting of nine 155-mm square columns and twelve 200-mm square columns. The concrete mix contained 2% (by weight) of end-hooked steel fibers and with concrete strengths ranging from 67 MPa to 88 MPa. The columns were tested in either concentric or eccentric compression with varying initial loading eccentricities. The study showed that the introduction of steel fibers into the mix design arrested the early spalling of the cover and increased the load capacity as well as the ductility of the columns over that of comparable nonfiber-reinforced specimens.
