圆中空夹层钢管自密实混凝土抗弯承载力试验研究

PURE BENDING OF SELF-COMPACTING CONCRETE-FILLED DOUBLE SKIN STEEL TUBES

  • 摘要: 该文对5个空心率变化范围为0.00~1.00的圆中空夹层钢管自密实混凝土纯弯构件进行试验研究,分析其抗弯承载力与空心率之间的关系,试验表明:这种结构形式具有较好的变形能力和后期抗弯承载力;在空心率为0.71时,抗弯承载力较高;在试验过程中,构件的截面中和轴向受压区移动。

     

    Abstract: Pure bending tests were carried out on self-compacting concrete-filled double skin steel tubes with five different hollowness ratios (0.00~1.00) to study the relationship between pure bending and the hollowness ratio, The test results showed that this kind of structure has good deformation resistance and late-stage bending bearing capacity. Also, at a hollowness ratio of 0.71, the flexural bearing capacity is high, and in the course of the experiment, both the compression zone and the section center experienced movement.
