Mechanical behavior of steel fiber‐reinforced self‐compacting concrete corbels after exposure to elevated temperatures
The paper presents an experimental study to investigate the effect of steel fiber (SF) on the mechanical behavior of self‐compacting concrete corbels after exposure to elevated temperatures. This research examines the most relevant parameters that influence the behavior of reinforced concrete corbels (RC‐corbels). These parameters comprise of the grade of concrete (medium [C50] and high strength concrete [C80]), the shear span‐to‐depth ratio (0.6 and 0.8), and the reinforcement ratio (0.82 and 1.6%). RC‐corbels were prepared from self‐compacting concrete with a constant percentage of polypropylene fiber of 0.1% and three different SF volume fractions of 0, 0.5, and 1.0%. All RC‐corbels were tested before and after exposure to elevated temperatures (250, 500 and 750 °C). The results were presented in terms of load–deflection curves, crack patterns and failure modes. Results showed that the SFs have a positive effect on load‐carrying capacity and ductility of RC‐corbels both before and after exposure to elevated temperatures.
