| 摘 要： | 根据普通混凝土的有限元分析理论,建立了混凝土梁的有限元分析模型,根据计算结果,提出了钢纤维均匀分布、按应力状态分布和梯度分布等三种钢纤维分布形式,并探讨了各种形式对混凝土梁平截面假定和抗弯强度的改善效果.结果表明,采用钢纤维梯度分布形式的增强增韧效果更为显著. |

| Abstract: | On the ground of the finite element theory of normal concrete, the finite elemental model was established. Based on the calculated results, the three distribution method of steel fiber such as uniformly, by stress distribution and gradient distribution were put forward. The improvements on plane assumption and flexural strength concrete beams was discussed. The results indicated that the reinforcing effect of gradient distribution on strength and ductility were more efficient than that of other distribution. |
| Keywords: | fiber gradient distribution finite element |
