摘　　要：通过16个型钢混凝土短柱试验,分析了型钢-混凝土的粘结机理,探讨了配箍率、混凝土强度、混凝土保护层厚度等因素对轴心受压短柱粘结性能和极限承载力的影响。通过编程建立有限元模型,可为型钢混凝土轴压柱极限承载力和粘结强度的计算提供参考。Based on the experimental results of 16 steel reinforced concrete（SRC） short-columns, bond behavior between shaped steel and concrete is analyzed. It is also explored that the effects of concrete strength, the thickness of concrete cover, and the ratio of lateral stirrup on the bond behavior and ultimate bearing capacity of the short column subjected axial loads. Finite element model is set-up to further study bond-slip behavior between shaped steel and concrete, which would be a reference to calculate bond strength and ultimate bearing capacity of SRC columns subjected axial loads.
