Abstract
Given the fact that FRP bolts for roadway support are often under a certain amount of eccentric load, we studied the problems of failure of FRP bolt-ends using mechanical analysis, numerical simulation and a laboratory experiment to reveal the FRP bolt-end failure mechanism. The results show that bolt-end stress increases rapidly, making the maximum stress under an eccentric load to be 5 to 7 times greater than that under a normal load, resulting first in the formation of some fractures at the bolt-end, which then spreads to the entire cross-section of the bolt.
