Abstract

Steel fiber reinforced concrete (SFRC) (an impact resistant material) has a good energy dissipation capacity and ductility through the developing of impact toughness and tensile strength. Due to lack of adequate data over the dynamic performance of SFRC in previous studies, the design procedures and analyzing of SFRC are under investigation. The current study has focused on the empirical test and the finite element analysis (FE) of dynamic response for SFRC slabs and beams containing mixed aspect ratio of steel fibers (SFs) subjected to impact loading. Adding SFs increased the slab capacity and reduced the crack spacings.

冲击荷载作用下钢纤维混凝土构件混合纵横比的动态获得

摘要

钢纤维混凝土（SFRC）（一种抗冲击材料）通过提高冲击韧性和抗拉强度，具有良好的耗能能力和延展性。由于以往研究中缺乏足够的 SFRC 动态性能数据，目前正在研究 SFRC 的设计程序和分析。目前的研究主要集中在经验测试和有限元分析（FE）的动态响应包含钢纤维（SFs）的混合纵横比的SFRC板和梁在冲击载荷下。添加 SF 增加了板坯容量并减小了裂缝间距。
