Fatigue Model of Composite Concrete Structure under Flexure

摘要：

　　Taking the CRTS II type slab ballastless track structure as the test prototype,the concrete-CA mortar composite model specimen (100)was built 100 mm3 400),based on fatigue tests under four-point bending loading conditions of composite model specimens and applied fatigue loads MTS universal servo hydraulic fatigue testing machines,Six static flexural tests also conducted to determine the static flexural strength of CCS prior to fatigue testing.Based on the experimental results,the fatigue expression of CCS specimens under flexural fatigue load is proposed.the evolution curves of damage variables and fatigue deformation are obtained.
