Study On Fatigue Of Layer Steel Fiber Reinforced Concrete

The Wuhan University of technology and Dongzhou SFRC Inc bring forward LSFRC pavement together. LSFRC pavement is a type of new composite pavement by putting certain quantity of steel fiber in the bottom and top of the pavement. The production has been declared to "Specification of fiber concrete structure" and confirmed to be subjoined in fiber steel reinforced concrete and airdrome path of chapter eitht in the specification.The research of fatigue on LSFRC is subsequence of the research above. By fatigue test of 70 beams measured 150x150x550, this paper study fatigue of SFRC. Firstly, this paper get fatigue life and fatigue strain of the beams by test, validate the better fatigue value of SFRC by the contrasting test of plain concrete beams. By probability analysis, this paper find normal school and Weibull are both can be used to simulate the fatigue life of SFRC, but Weibull if better. Then this paper define damnification of SFRC, and study the order of SFRC' s damnification by analyzing the data of the fatigue test. At last, this paper desigh a section pavement of SFRC and bring forward a way to construct SFRC pavement.
