Abstract
In order to minimize the loss of life and property in an earthquake, the beam-column joints of buildings need to have good seismic performance. This paper briefly introduced concrete beam-column joints and used a steel skeleton to strengthen the seismic performance of concrete beam-column joints. The concrete beam-column and reinforced concrete beam-column joints were prepared for experimental analysis. The skeleton curve and energy dissipation capacity of the joints were tested using quasi-static loading experiments. The relative displacement of the column at different heights in the beam-column joints was tested under an eight-degree earthquake simulated by a vibration table. The results showed that the reinforced concrete beam-column joint had higher peak loads and ultimate displacements when the quasi-static loading displacement exceeded the yield displacement; the reinforced concrete beam-column joint had stronger energy dissipation capacity in the face of cyclic loads; the reinforced concrete beam-column joint had smaller relative column displacements in the face of an eight-degree earthquake.
