| 摘 要： | 通过6个钢筋混凝土框架异型中节点试件在低周反复荷载作用下的试验,分析节点核心区尺寸、轴压比等因素对异型节点抗震性能的影响。研究表明:上柱截面发生变化对异型节点抗震性能的影响不明显,当其变化量小于1/6柱高时,即Δhchbl/2时,建议按中间层边节点考虑。此外,轴压比增大对异型节点通裂阶段后组合体试件的抗震性能产生不利影响,对该类节点进行抗震设计时,建议轴压比应小于0.3。

| Abstract: | Six specimens of abnormal interior joints were tested under reversed cyclic loading.Experimental studies were carried out to investigate the effect of joint core dimensions and axial compression ratio on seismic behaviour of abnormal joints.Test results indicated that column section abrupt had little effect on seismic behavior of the specimen.When the reduced height of column section was less than 1/6 column section height,that is Δh_c
