Abstract Research purpose: It is for China to better apply the universal analysis model for resisting shear to reinforced concrete beam-column node lately published in "ACI Structural Journal" edited by American Concrete Association.
Research method: The check and modification are made to this universal analysis model for resisting shear through summing up the experimental test data of resisting shear of different kinds of beam-column nodes in China. The analysis is made of the influences on shear strength of node by the parameters of ratio of hoop, ratio of reinforcement and ratio of axial pressure.
Research result: The check result shows although the prediction result of this model basically conforms to the experimental data of beam-column in China, but some times the result of node shear strength estimated by this model is unfavourable for safety.
Research conclusion: On the basis of the check results of different kinds of beam-column node got by the research team in China, the improvement proposals are given for three factors of this model. The prediction result of modified model is close to the experimental result and is favourable for safety.
