Influence of Fiber Embedded Length on Properties of Single Fiber Pull-Out Test
The reinforcing and toughening effect of fiber reinforced concrete (FRC) are mainly under control of the interfacial bond strength in between of fiber and concrete, and the embedded length of fiber is one of the significant factors for interfacial bond strength. In this paper, pull-out numerical models based on single steel or polypropylene fiber have been studied with the fiber embedded length set as a variable and the influence of fiber embedded length on properties of single fiber pullout has, therefore, been analyzed. The results indicate that the longer the fiber embedded length, the larger the peak index and pull-out toughness of single fiber pull-out specimen could be reached, while the interfacial bond strength would decrease. The variation of fiber embedded length has only a little impact upon the damage process of pullout. Finally, the test results for specimen with the polypropylene fiber is more sensitive to the changes of embedded length compared those with steel fiber
