DESIGN OF HSC COLUMNS WITH STEEL FIBERS

Prior research has shown that high strength concrete (HSC) columns are subject to early spalling of the concrete cover and that this spalling leads to lower strength. It has also been documented that HSC columns have poor ductility unless high quantities of tie reinforcement are used. This paper shows that the inclusion of steel fibers into the concrete mix significantly enhances the ductility of the section and lowers the demand for closely spaced ties. A design model for calculating the ductility of fiber reinforced HSC columns is provided.
