Abstract—Externally bonded Fiber Reinforced Polymer
(FRP) materials can be used to increase the shear strength of
reinforced concrete (RC) structural members. These composite materials are typically based on organic matrices, which are
used to impregnate the fibers and provide bond to the concrete surface. Existing analytical models were derived using experimental data from specimens strengthened with organic specimens. The aim of this study is to evaluate these models and verify if these models can be used also for specimens that
utilize inorganic matrices. The methodology used in this study
is based on a comparison of experimental values obtained from specimens strengthened with inorganic matrices to analytical values calculated using the aforementioned models. It is concluded, that most of the models for organic matrices can also be used for inorganic, but for a better correlation of
results some adjustments are necessary.
