An experimental study on hybrid fiber reinforced concrete beams subjected to torsion

Experimental investigations were carried out to study the mechanical performance and torsional behaviour of hybrid fiber reinforced concrete beams. Steel fibers and Glass fibers were used with varying fiber content such as 0% 0.5% 1.0% and 1.5% by volume of concrete to cast the specimens for this study. The experimental study results confirmed that the mechanical performance of the concrete was remarkably improved with the addition of hybrid fibers upto 1% by volume of concrete. The torsional strength in the cracking state and post cracking state was improved in hybrid fiber reinforced concrete and this depends on the volume of fiber content in concrete.

Automated summary

Experimental investigations showed that mechanical performance of concrete was significantly improved with the addition of hybrid fibers up to 1% by volume of concrete. Torsional strength in both cracking and post-cracking states was enhanced in hybrid fiber reinforced concrete, depending on the volume of fiber content in concrete. This study suggests the potential advantages of hybrid fiber reinforced concrete in structural applications, effectively improving the performance of concrete.
