Abstract:

Experimental study of cylindrical samples under uniaxial cyclic compression was conducted to explore the effect of loading frequency and stress level on fatigue performance of ultra high toughness cementitious composite （UHTCC） under traffic loading. The results show that accumulation rate of stress-cycle curves could be disassembled into three stage with increase in number of cycles. Meanwhile， nonlinearity of strain increases gradually. The increase of loading frequency and stress level would reduce the fatigue life of specimens. The constitutive model for UHTCC was proposed based on the basis of uniaxial compression cyclic tests. Moreover， the stress path predicted by the model is in good agreement with the experimental results， which verifies the correctness and applicability of this model. Fatigue damage propagation is characterized by dissipated strain energy （DSE） based on energy-based mechanistic approach （EBM）. The initial damage （about 2%） is obtained and the development law of fatigue damage factor is revealed. Additionly， the fatigue cracking is fast at high stress ratio.

Key words: ultra high toughness cementitious composite, energy-based mechanistic approach, constitutive model, fatigue, dissipated strain energy
