Reliability‑based analysis of the flexural strength of concrete beams reinforced with hybrid BFRP and steel rebars

Original language description

The durability of reinforced concrete structures has always been an important problem in civil engineering because steelnrebars rust easily. Therefore, fiber-reinforced polymer (FRP) rebars possessing good corrosion resistance, low weight, andneasy construction has become a substitute for reinforcement. However, since FRP rebar has a low elastic modulus and is anbrittle failure material, large deflections and cracks occur in the FRP concrete beam with no obvious warning before failure.nA hybrid reinforced concrete beam that combines the advantages of steel rebar and FRP rebar is a good structural form.nThe reliability of hybrid reinforced beams must be analyzed to ensure their safety. A flexural performance test of the hybridnbasalt FRP (BFRP)–steel-reinforced beam was performed, the failure mode was explored, and the numerical models werenestablished. The accuracy of the models was verified by comparing them with the test results. The numerical models werenused to establish a database (630 cases) that was combined with existing research results (33 cases), to obtain the statisticsnof the uncertainty of the prediction model. Reliability analysis of a large-scale design space was conducted to calibrate thenBFRP. Finally, the average deviation from the target reliability index suggested that the values of the partial coefficient ofnthe materials range from 1.2 to 1.4.
