摘　　要：完成了取自实际工程的两个十字形穿心暗牛腿式钢管混凝土柱节点的足尺试验． 基于对试验结果的分析， 揭示了钢管混凝土柱节点的受力性能和破坏形态， 检验了这种柱节点构造型式的承载能力， 并对这种柱节点方案作了分析和评价， 为柱节点的设计提供了依据．In this paper, a series of tests with dimension ratio 1∶1 on two specimens of concrete filled steel tubular(CFST) column joints which have steel brackets through tubular core, have been carried out. Based on the analysis of test results, the load transfer mechanism and failure model of CFST column joints are presented. The loading capacity of these joints is verified. Some analysis and evaluation about the formation of CFST column joints are given, and advice on the design is also offered.
