钢骨-钢管混凝土轴压短柱承载力研究

STUDY ON LOAD-CARRYING CAPACITY OF STEEL-CONCRETE-FILLED STEEL TUBE COLUMN

把钢骨-钢管混凝土组合柱视为一个新型组合材料的统一体,结合试验成果,分析轴压短柱承载力的影响因素,提出影响组合柱承载力和延性的因素,即约束指标,提出钢骨-钢管混凝土轴压短柱的承载力公式。

The steel tubular columns filled with steelreinforced highstrength concrete can be regarded as the unified material Experiments of the short composite column under axial compression are carried out to investigate the mechanical properties of working feature,loadcarrying capacity and ductility etc,and the effects of main factors on these properties are discussedFormulas with restriction index used for predicting the ultimate bearing capacity of the short composite column,are proposed
