Abstract
This paper described the time-dependent failure characteristics due to creep and fatigue of FRP rods with glass and aramid fibers and proposed an estimating method. At first, the results of creep and fatigue test of fibers themselves confirmed that the characteristics were strongly affected by the level of creep and fatigue and could be analyzed by the theory of failure probability by Weibull. Moreover, the simulation model on the destruction of FRP rods was constructed considering the time-dependent characteristics of fibers themselves and matrix resin. The simulative and experimental results provided the good agreement between them. Consequently, the simulation model developed here made it possible to evaluate the time-dependent failure characteristics of FRP rods.
