Abstract
The synergy effects of reinforcing rebars and Hybrid Fiber Reinforced Cementitious Composites (HFRCC) were experimentally investigated on the mechanical behavior of structural elements and on the cracking distribution. Uniaxial tension tests with prism specimens were carried out in order to evaluate the influence by changing the fiber volume content and the rebar diameter. As the result, the optimum combination to maximize the synergy effect of the rebar and HFRCC was found. In comparison with the influence of the rebar diameter, it was confirmed that the fiber volume content more influences on the synergy effect than that of the rebar diameter.
