Abstract

This study aims to propose a theoretical calculation formula to predict crack width of reinforced concrete members both for steel and FRP reinforcement. The proposed formula is led by solving the force equilibrium and compatibility conditions in the bond problem under the assumption of bond constitutive law (bond stress - slip relationship). A pullout bond test is conducted for the specimens with one reinforcing bar arranged in the simple concrete block. The bond stress - slip relationship of test result is used to confirm the adaptability of the proposed formula by predicting crack width of the specimen for a tensile bond test, which is also conducted in this study. The strain - crack width curve predicted by the proposed formula shows a good adaptability with the experimental result.
