摘　　要：通过3个钢筋混凝土梁柱节点核心区在低周往复荷载下的试验,得到3个节点在梁柱核心区加钢丝网片和未加钢丝网片时抗震性能差异。在梁柱核心形态,通过分析3个试件的最终破坏形态及裂缝的样式和它相应的荷载-位移滞回曲线。结果表明:在梁区域加钢丝网片,试块的极限荷载有所提高,荷载-位移滞回曲线相对饱满,抗震性能得到了加强,所得结论可为实际工程中相应的抗震设计提供参考。Through the test of the core area of three reinforced concrete beam-column joints under low-cycle reciprocating load,the seismic performance difference between the three nodes in the core area of the beam and column and the steel wire mesh is obtained.In the core shape of the beam and column,by analyzing the final failure mode of the three specimens and the pattern of the crack and its corresponding load-displacement hysteresis curve.The results show that the steel bar is added to the beam region,the ultimate load of the test block is improved,the load-displacement hysteresis curve is relatively full,and the seismic performance is strengthened.The conclusions can provide reference for the corresponding seismic design in practical engineering.
