摘要 针对混凝土强度对钢管混凝土受压短柱刚度的影响,进行了试验研究。结果表明,随着混凝土强度的增高,混凝土弹性模量的增大,构件的竖向和抗弯刚度均增大。混凝土强度对钢管混凝土受压短柱刚度的影响程度为:轴压构件>小偏压构件>大偏压构件。 The effect of concrete strength on the stiffness of concrete filled steel tube short columns under compression is studied by some experiments. The results show that with the increasing of strength and elastic modulus of concrete, vertical and flexural stiffness of the components are all increased. And the influence degree of concrete strength on the stiffness of concrete filled steel tube short columns under compression: axial compression member 〉small eccentric compression member〉large eccentric compression member.
