［摘要］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。

Abstract:Through low cyclic loading tests of cast-in-place reinforced concrete frame joints and prefabricated frame joints with additional angle steel under different prestress, seismic performances of the beam-column joints were studied including failure process, hysteretic curve, and deformation properties and so on. Experimental results show that compared with cast-in-place reinforced concrete frame joints, prefabricated frame joints with additional angle steel has slighter damage, and there is a good energy dissipation capacity and small residual deformation, which is beneficial to seismic resistance.

Keywords:prefabricated frame structure； joint； angle steel； seismic performance
