摘　　要：通过分析国内外对方钢管混凝土柱力学性能的研究,总结了不同约束方式的方钢管混凝土柱的轴压性能、压弯性能、抗震性能、局部屈曲和轴向承载力计算公式。结果表明:各种不同的加劲约束措施能提升钢管对混凝土的约束作用,改善了柱的延性与抗震性能。计算方钢管混凝土柱的轴向承载力时,应考虑约束措施对核心混凝土的影响,以提高计算精度。最后对不同约束方式的方钢管混凝土柱的研究进行了总结与展望。By analyzing the mechanical properties of concrete-filled steel tubular columns at home and abroad,the calculation formulas of axial compression properties,flexural properties,seismic properties,local buckling and axial bearing capacity of concrete-filled steel tubular square columns with different constraints are summarized.The results show that various stiffening restraint measures can enhance the restraint effect of steel pipe on concrete,and improve the ductility and seismic performance of columns.When calculating the axial bearing capacity of concrete-filled square steel tube column,the influence of restraint measures on the core concrete should be considered to improve the calculation accuracy.Finally,the research on concrete-filled square steel tube columns with different constraints is prospected and summarized.
