Flexural Fatigue Behavior of Layered Hybrid Fiber Reinforced Concrete

摘要

In order to obtain the fatigue life of layered hybrid fiber reinforced concrete(LHFRC) at different stress levels,flexural fatigue tests were carried out on specimens.The relation between fatigue lives and stress levels was simulated using the two-parameter Weibull distribution.Furthermore,both single- logarithmic and double-logarithmic regressive equations of various reliabilities were derived.It is evident that LHFRC gets the advantage of longer fatigue life over common concrete.
