摘要：
The fatigue strength of concrete under cyclic loads of vehicles is an important problem in calculation and design of bridge engineering. Based on this viewpoint, the fatigue tests of plain concrete under constant-amplitude and stepping-amplitude cyclic loads were conducted. The damage mechanism of plain concrete specimens under high-frequency fatigue loads was analyzed and the nonlinear accumulative fatigue damage formula was proposed. The fatigue equation P-S-N considering the failure probability p' was given. The above-mentioned research results made a good preparation for further study on high-frequency fatigue tests of concrete cylinders reinforced with carbon fibers.
