根据文献[1]给出的钢材和核心混凝土本构关系，应用简化数值积分方法对由方钢管和核心混凝土两种材料组成的方钢管混凝土偏心受压构件进行了轴向力─柱中截面中心挠度全过程分析，文中给出了算例并利用文献[2]的试验结果对文中的计算方法进行了验证。
According to the constitutive relationship between steel and core concrete given in [1], a simplified numerical integration method was applied to the axial force of the square steel-concrete eccentric compression member consisting of square steel pipe and core concrete. The whole process of deflection is analyzed. The examples are given in the paper and the calculation method in the paper is validated using the experimental results in [2].
