Abstract

In this paper, an AnSYS finite element simulation analysis was conducted to study the influences of different types of steel fibers on the ultra-high performance concrete beams in the initial cracking state and yield state of bending performance. The results indicate that the incorporation of steel fiber can improve the mid-span moment and stress in the initial crack state and yielded state and prevent the concrete from cracking, thereby improving the flexural behavior of the beam. The higher the tensile strength of the fiber, the more obvious the improvement effect is. In this paper, the end hook type fiber with the tensile strength of 1100MPa exhibits the best enhancement effect. The formula of ultimate flexural capacity for UHPC beam is deduced.
