ABSTRACT

The behavior of laterally confined concrete prisms with steel fibers has been experimentally investigated. Prisms were loaded monotonically in the main (axial) direction until failure. Lateral confinement was provided by steel stirrups. One fiber volume and aspect ratio of 1% and 75, respectively, have been used. The main variable considered in this study was the method of curing. Identical specimens were cured either in water or under atmospheric conditions or in the environmental room under constant temperature of 60 °C. In addition, two stirrup diameters and two spacings were also used. Results were discussed regarding general behavior, strength, ductility and energy absorption and dissipation capacity. A noticeable enhancement in both strength and ductility was observed with some of the test specimens, while others showed much lower values, depending on the test variable used.
