(Beijing Key Lab of Earthquake Engineering and Structural Retrofit, Beijing University of Technology, Beijing 100124, China)Abstract: Disasters aroused by several earthquakes show that in the reinforced concrete frame structure, most destruction occured in the core node area or in other parts of columns. However, there is no agreement on the seisnuc design requirements in the reinforced concrete code in different countries. Through investigations and node tests for damage of reinforced concrete beam-column joints, main factors affecting seisnuc performance of nodes core zone were summed up, the existing shear capacity of reinforced concrete frame of basic theory and the node deformation analysis were reviewed, the theory of reinforced concrete beam-column joints of the latest calculation was summarized, and the main problems in the current study and research were pointed out.
Keywords: reinforced concrete; beam-column joints; shear capacity; seismic performance
