Abstract: Buried FRPM pipe culvert is a new kind of highway culvert type. Stress simulation of pipe culvert was carried out with indoor fatigue test, test results show that the strength and stiffness of FRPM pipe culvert was not significantly reduced under 2.5 million times of fatigue load, and layered peeling and brittle fracture phenomena do not appear, which could completely meet the requirement of the highway culvert application. This paper puts forward the fatigue residual stiffness in according with the highway standard, and the prediction formula of fatigue life calculation value is good agreement with the test results. This work provides reliable basis of the analysis for FRPM pipe in highway culvert of durability design.
