摘要
利用ANSYS有限元软件,研究了玄武岩纤维和聚丙烯纤维不同掺量对自密实混凝土梁在屈服状态下应力和跨中挠度的影响,并给出了相关回归方程,得到了最佳纤维组合掺量,为混杂纤维自密实混凝土梁抗弯性能的试验研究提供参考。
Using the ANSYS finite element analysis, the author researched the effects of the different dosage of basalt fiber and polypropylene fi-ber on the stress mid-span moment of the self-compacting concrete beam which was in the yield state in this experiment. The regression equation would be given in this paper and the best combination of fiber content, which can provide references for the relevant experimental study on flexur-al behavior of hybrid fiber reinforced self-compacting concrete beam.
