通过5个钢筋混凝土柱试件,试验研究了钢筋混凝土柱在反复循环轴向荷载下的轴力—变形特性,基于试验结果建议了一个钢筋混凝土柱的轴向刚度滞变模型。
Through five reinforced concrete column specimens, the axial force-deformation characteristics of reinforced concrete columns under repeated cyclic axial loads were experimentally studied. Based on the experimental results, a model of axial stiffness for a reinforced concrete column was proposed.
