本文阐述了该试验研究的结果,其目的在于了解用钢纤维增强的普通混凝土梁在纯弯曲时的变形性能。第一组梁是钢纤维分布在整个体积梁内,而第二组梁只在其受拉侧分布了一半高度的钢纤维,然后对这些梁的变形性能做了对比性研究,结果表明:一半高度的纤维含量虽然只是全高纤维含量的一半,但在提高梁的变形性能方面,却具有相同的效果。因此,通过这种钢纤维的分布方式,就能使价值昂贵的钢纤维得到经济的、有效的应用。
This article describes the results of this experimental study. Its purpose is to understand the deformation behavior of plain concrete beams reinforced with steel fibers in pure bending. The first group of beams is that the steel fibers are distributed in the entire volume beam, while the second group of beams only distributes half the height of the steel fibers on the tension side. Then a comparative study of the deformation properties of these beams is conducted. The results show that: Although the high fiber content is only half of the total high fiber content, it has the same effect in improving the deformation properties of the beam. Therefore, through the distribution of such steel fibers, valuable steel fibers can be economically and effectively applied.
