Research on Fatigue Strain and Fatigue Modulus of Concrete

2017-6-14  Concrete fatigue strain and fatigue modulus evolution play a vital role in the evaluation of the material properties. In this paper, by analyzing the advantages and disadvantages of existing concrete strain analysis methods, the level-S nonlinear fatigue strain model was proposed. The parameters’ physical meaning, the ranges, and the impact on the shape of the curve were all discussed.

Deflection, strain, and load data were acquired for each slab test. The results of the FSS fatigue tests were plotted as the stress ratio (bending stress in the slab divided by the concrete modulus of rupture) versus the number of cycles to failure. FSS had a resistance to fatigue 30 percent higher than simply supported beams (SSB).
