假设核心混凝土为刚性，矩形钢管混凝土柱的钢管板件在非加载边受到弹性约束而确定出钢管壁板的局部屈曲模型。为了推导出方钢管混凝土柱在轴压下钢管管壁的局部屈曲临界应力，我们采用了能量法。通过计算能够充分表明，核心混凝土能够有效的提高钢管管壁抵抗局部屈曲的能力。

If the core concrete is rigid, the local buckling model of steel plates is determined by the elastic constraints of steel plate of rectangular steel tubular concrete column in the non load side. In order to deduce the local buckling critical stress of steel pipe wall of square steel tube concrete column under axial pressure, we use the energy method. Through the calculation it fully shows that the core concrete can effectively improve the ability to resist the local buckling of the steel pipe wall.
