Abstract

In this paper, the effect of using Strain-Hardening Cementitious Composites (SHCC) to improve the shear behavior of reinforced concrete (RC) beams with web openings was experimentally investigated. A four-point bending test was performed on seven specimens. One of them, control beam BC , had no web opening, but the other six specimens were tested with web opening . The studied parameters were the effect of employing either plain or reinforced prefabricated SHCC and the influence of prefabricated SHCC configurations around web openings. On the basis of cracking patterns, load-deflection behavior, ductility, and initial stiffness, the shear behavior was evaluated. According to experimental findings, the presence of a web circular opening in the shear zone decreased the shear strength by about 46%. Nevertheless, the use of prefabricated SHCC shapes enhanced the shear strength of the tested specimens by up to 60% relative to the control specimen (BC-C). As soon as reinforcements were added to prefabricated SHCC, it was abundantly clear that the ultimate load and cracking behavior of RC beams with openings had improved.
