通过对现浇钢筋混凝土框架节点及不同预应力下附加角钢的预制装配框架节点进行低周反复荷载作用下的试验,研究梁柱节点的破坏过程、滞回曲线、变形性能等抗震性能。试验结果表明,相比现浇钢筋混凝土框架节点,附加角钢的预制装配框架节点破坏程度轻,且有很好的变形恢复能力,残余变形小,对抗震有利。 The seismic behavior of the beam-column joint under failure such as failure process, hysteresis curve and deformation performance was investigated by testing the prefabricated frame joints of cast-in-situ reinforced concrete frame and prefabricated prefabricated frames with different prestress under low cyclic load. The experimental results show that compared with the cast-in-site RC frame joints, the prefabricated assembly joints of the additional angle steel have less damage and good deformation recovery ability, and the residual deformation is small, which is beneficial to the earthquake resistance.
