Behavior of High-Performance Steel as Shear Reinforcement for Concrete Beams

摘要

In the introduction, the authors correctly point out that using high-performance steel in comparison with conventional steel could potentially relieve congestion in future structures. Nevertheless, it is odd that, for the nine reinforced beams, the same cross-sectional areas for longitudinal and shear reinforcement were applied without depending on the strength of the steel. This means that even the flexural beams' test results cannot be accurately compared to each other, as the tensile forces and the concrete compression zones are completely different. Choosing the same cross-sectional area for the longitudinal MMFX bars, the authors want to keep the effect of dowel action constant.
