Behavior of Post-Installed Bonded Bars as Shear Reinforcement

“…The previously proposed simplified model can be used to analyse the behavior of post-installed unconfined bonded bars in shear strengthened RC members. This type of shear strengthening as well as cast-in-place stirrups were used in beams tested by Cusson 4 and Provencher 3 . These Additional information about the beams specimens can be found in Fig.…”

“…Based on the detailed numerical results, a simplified model is proposed to predict the behavior of post-installed epoxy-bonded bars. The predictions using the detailed numerical model and the simplified model are compared with the behavior of post-installed epoxy-bonded shear reinforcement as well as the behavior of cast-inplace stirrups observed from experiments [3][4][5] . Therefore, the proposed models can be used to predict shear carried by epoxy-bonded shear reinforcement in RC structures.…”

“…This technique involves choosing a bar size as well as the spacing along the span and transverse to the span. Experiments have demonstrated that the shear capacity can be greatly increased using this technique [3][4][5] . However, it is necessary to adjust the predictions using current shear design methods for members containing conventional shear reinforcement (stirrups installed before concrete casting) in order to predict the shear capacity of members with post-installed epoxy-bonded bars.…”

“…The behavior of post-installed, epoxy-bonded, shear reinforcing bars differs from the ideally anchored cast-in-place stirrups. Assuming that the epoxy-bonded bars are ideally anchored can result in an overestimation the shear capacity by about 30% [3][4][5] .…”
