采用有限元软件ANSYS对隔板贯通式圆钢管混凝土柱-翼缘削弱钢梁连接节点的参数进行分析.在参照SAC推荐标准的基础上,验证隔板贯通式节点狗骨处参数的取值范围,并细化.结果表明:狗骨处的三个参数——削弱深度c、削弱端至焊缝的距离a和削弱长度b对节点的极限承载力的影响依次降低.当a=(0.5～0.65)b∫;b=(0.65～0.85)db;c=(0.20～0.25)b∫时,该节点的性能最优.%This paper focuses on the parameters analysis of concrete filled steel tube (CFST) column to RBS beam connections with crossing diaphragm using finite element analysis software of ANSYS. Base on SAC Recommendation, the reasonable value range of the design parameters in RBS were verified and clarified. It found that the ultimate bearing capacity of diaphragm - through style beam - column joint drop successively from c (the depth of the cut) , a{ the distance from the fringe of diaphragm to the start of the cut) to 6( the length of the cut). In addition, the mechanical properties of joint is excellent when a =0. 5 -0. 65bj;b =0. 65 -0. 85d,50=0.20-0.25bf.
