In this study, 10 different types of walls were made by fiber reinforced self-compacting concrete. The concrete walls were reinforced with steel and nylon fibers. The results of rheological tests showed that the steel and nylon fibers have a negative effect on flowability of self-compacting concrete, which the negative effect of steel fibers was more significant in this regard. On the other hand, the results of mechanical tests indicated that the steel fibers have a slight effect on the compressive strength and considerable effect on tensile and flexural strength, whereas, nylon fibers have no significant effect in these cases. In this study, two methods, including uniform distribution and targeted distribution of fibers, were used to reinforce the concrete walls. In the uniform distribution method, all the used fibers were uniformly distributed in the wall, while in the targeted distribution method the used fibers were distributed in the wall, with a more volume of fibers in the surrounding layers and a fewer volume of fibers in the middle layer of the wall. The concrete walls were tested by bullet fire. The results of this test showed that steel fibers could significantly decrease the penetration depth of bullet in concrete walls, while nylon fibers had a much lower effect. By comparing the penetration depth of the bullet in the walls, it was observed that the targeted distribution of fibers was effective to decrease the penetration depth of the bullet.

在这项研究中，纤维增强自密实混凝土制成了10种不同类型的墙。混凝土墙用钢和尼龙纤维加固。流变试验的结果表明，钢纤维和尼龙纤维对自密实混凝土的流动性具有负面影响，在这方面，钢纤维的负面影响更为显着。另一方面，机械测试的结果表明，钢纤维对压缩强度的影响很小，而对拉伸和挠曲强度的影响却很大，而在这些情况下，尼龙纤维没有明显的影响。在这项研究中，使用了两种方法，包括纤维的均匀分布和目标分布，来加固混凝土墙。在均匀分配方法中，所有使用过的纤维均均匀地分布在壁中，而在目标分配方法中，使用过的纤维则分布在壁中，周围层中的纤维更多，而壁中层的纤维更少。混凝土墙通过子弹射击测试。该测试的结果表明，钢纤维可以显着降低子弹在混凝土墙中的穿透深度，而尼龙纤维的效果要低得多。通过比较子弹在壁中的穿透深度，可以观察到纤维的目标分布有效地减小了子弹的穿透深度。围层中的纤维量更多，而墙的中间层中的纤维量更少。混凝土墙通过子弹射击测试。该测试的结果表明，钢纤维可以显着降低子弹在混凝土墙中的穿透深度，而尼龙纤维的效果要低得多。通过比较子弹在壁中的穿透深度，可以观察到纤维的目标分布有效地减小了子弹的穿透深度。围层中的纤维量更多，而墙的中间层中的纤维量更少。混凝土墙通过子弹射击测试。该测试的结果表明，钢纤维可以显着降低子弹在混凝土墙中的穿透深度，而尼龙纤维的效果要低得多。通过比较子弹在壁中的穿透深度，可以观察到纤维的目标分布有效地减小了子弹的穿透深度。
