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．
The full-scale test of two cruciform pierced dark bulge type concrete-filled steel tubular (CFST) column joints from the actual project was completed. Based on the analysis of the test results, the mechanical properties and failure modes of the concrete-filled steel tubular column joints were revealed. The load-carrying capacity of this type of column joint structure was examined. The analysis and evaluation of this column node scheme was performed. Design provides the basis.
