Abstract

Abstract

In order to study the calculation method for the bearing capacity of wet joints of beam bridges equipped with circular steel bars, collected the test data and calculation methods were collected systematically, and it was found that:1) the existing calculation methods for the bearing capacity of joints were based on the bearing capacity of the specimen under tension, the main difference was the calculation of the tensile strength of the core concrete area and the control factors of the tensile strength of the specimen; 2) the theoretical values obtained by the plastic work model calculation method proposed by Joergensen was closer to the experimental values, and the data dispersion was small and more stable; 3) strut-and-tie model of HE Z-Q reflected the failure mode and stress mechanism of wet joints of circular steel bars better than other models. Since the current calculation method still had a certain error from the actual situation, it was recommended that the calculation method that was more suitable for the bearing capacity of the wet joints of beam equipped with circular steel bars should be derived from the failure mode and the stress mechanism in the future.
