Abstract: Based on an existing RC beam-column joint shear model, a new shear model for RC beam-column joint with high-strength stirrups was proposed, which considers the strut mechanism of concrete and shear mechanism of stirrups of RC beam-column joint. The calculated results indicate that the shear stress-strain curves calculated by the proposed model agrees well with the test curves. The average value of the ratios of calculated results and test results of the maximum shear stress is closed to 1, and the corresponding coefficient of variation is smaller. The beam-column joint shear model was applied in OpenSEES platform to analyze the mechanic behavior of RC joint with high-strength stirrups. The effect of concrete strength and axial compressive ratio on the performance of RC beam-column joint was discussed. The model is feasible for the mechanical analysis of RC beam-column joint with high-strength stirrups.
