However, it is necessary to know what effect this replacement has on the development of concrete cracks, which is inevitable in CRCP. Concrete shrinkage and temperature variations are known to be the principal factors for early-age crack formation in CRCP. By employing an analytical model, this study presents the shrinkage and thermal stress distributions in concrete due to the restraint provided by GFRP rebars in comparison with that provided by steel rebars. It reveals the advantages of using GFRP rebars as reinforcement in CRCP in terms of internal tensile stress reduction in concrete. Numerical calculation of the concrete stress distribution in a GFRP reinforced CRCP section subjected to thermal change is also presented.
