摘要

本文研究了有纤维和无纤维混凝土梁的受力性能。在实验部分，共制作了16个不同截面尺寸的梁试件。12个试件用合成纤维增强，以提高混凝土的韧性、冲击强度和疲劳强度。样品的纤维质量比在0% ~ 0.20%之间。试样进行了四点弯曲试验，以获得最大载荷和位移值，直到达到破坏模式。随后，在Abacus有限元分析软件中对梁样进行建模。通过对试验值和数值值以及试件应力分布的比较，可以看出，在研究不同尺寸梁在四点弯曲中的行为时，数值分析是一种选择。

Experimental and numerical study of fiber reinforced concrete beams in four-point bending

In this study, the behavior of concrete beams with and without fiber was investigated. In the experimental part, a total of 16 beam specimens were manufactured having different section sizes. 12 specimens were reinforced with synthetic fibers, that provide toughness, impact, and fatigue strength to concrete. The fiber ratios of the samples varied between 0% and 0.20% by mass. The samples were subjected to a four-point bending test to obtain the maximum load and displacement values, until they reached the failure modes. Subsequently, the beam samples were modelled in the Abacus finite element analysis software. Due to the comparison of experimental and numerical values and stress distributions of the specimens, it is seen that numerical analysis could be an option when investigating the behavior of beams with different dimensions in four-point bending.
