Abstract:

Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber content was varied: 0%, 0.38%, 0.70% and 0.94% by volume. The contribution of the steel fibers to the damping ratio and maximum response depended on the frequency, fiber content and amount of major cracking. For beams with resonant frequencies less than 7.5 Hz., increased cracking and fiber content decreased the maximum response (18%-28% when compared to the beam without steel fibers).
